This study was performed to examine the distribution of mean body surface temperature in 11 clinically healthy dogs. In stable state, ventral and dorsal part of each individual is scanned by digital infrared thermography. The body surface temperature of dorsocranial(DCr), dorsocaudal(DCd), ventrocranial(VCr) and ventrocaudal(VCd) regions were measured by Region Of Interersts(ROI). The mean body surface temperatures of adult dogs were higher than those of puppies in each regions. In addition mean body surface temperature of the ventral region was higher than that of dorsal region.

Acartia bifilosa has been classified as Rostratae group of Acartia by the characteristic of having the rostral filament. However, we have found that A. bifilosa does not have any rostrum. Therefore, A. bifilosa should be classified as Arostratae group. For the first time, we have observed that this species has only one genital pore in the genital segment. Two spermathecal canals are looped in lateral view as well as ventral view. We have also observed two thin, very short filaments and minute apertures on the anterio-ventral part of the top of the head. The function of the filaments need to be investigated.

A new halacarid species, Agaue laeviunguis n. sp. from Youngil Bay, Pohang City, South Korea is described. In sharing the character combination of three dorsal setae on PE, lacking dorsal seta anterior to insertion of leg IV, three ventral setae on PE, female PGS adjacent to GF, telofemora devoid of fovea, well developed smooth cerotegumental lamella on all telofemora, presence of accessory process on all lateral claws, long gnathosoma, and a smooth seta on P2 in both sexes, this species resembles A. subglabra Bartsch from Australia. The species, however, is clearly distinguished from A. subglabra by its larger body, claws of tarsi II-IV without ventral pecten, and much more PGS in female. Description of proto- and deutonymphs are also provided.

Putative gamma aminobu%sic acid (GABA)-ersic elements in the basilar pontine nuclei were examined in the dos using an antiserum against GABA-glutaraldehvde-protein conjusBtes and the peroxidase-antiperoxidase method. GABA-immunoreactive neuronal somata in the basilar Pons exhibited various morphology with the majority being spindle-shaped or multipolar, while some were spheroidal. The size of GABA-orgic neuronal somata was relatively small (approximately $10-20\mum)$ in diameter. GABA-immunoreactive neurons were scattered throughout the pontine nuclei, but the midline region of the medial nucleus at the rostral pons, the lateral nucleus at mid-pontine levels, and the ventral nucleus at the caudal pons exhibited a relatively greater concentration of cell bodies. A sparse number of GABA-ergic neurons were observed within the cerebral peduncle and along the ventral borders of the basilar pons adjacent to the middle cerebellar peduncle at the rostrocaudal levels of the pontine nuclei. These obsenrations provide anatomic evidence of how this inhibitory neural element performs its function in the cortico-prontocerbellar circuitry.

A new haplosplanchnid cercaria, Cercaria kuwaitae VI sp. n., was found in the prosobranch snail Cerithidea cincingulata in the Kuwait Bay Details are presented on the morphology and behavior of the cercaria and the encystment process. The new cercaria is a biocellate, distome, with a prominent single sac-like intestinal cecum extending well posterior to the ventral sucker and develops in simple sporocysts. It differs from known haplosplanchnid cercariae in the absence of finger-like processes on the tail, and the presence of V-shaped excretory vesicle extending beyond ventral sucker and the presence of cervical glands. The surface topography of the cercaria and its sporocyst is examined by scanning electron microscopy. This is the first haplosplanchnid cercaria to be described from a Cerithidea species.

A new marine halacarid species of the genus Agauopsis Viets, 1927 (Acari: Halacaridae) is recorded from Jeju Island, Korea. Agauopsis tetrasetosa n. sp. belongs to the microrhyncha group in sharing one ventral and three ventromedial spines on tibia of leg I, of which two ventromedial ones are adjacent to each other, with its 20 congeneric members. Agauopsis tetrasetosa n. sp. is most similar to A. miliaris Bartsch, 2005 and A. similis Bartsch, 1979 in sharing the similar chaetotaxy of legs I-IV, positions of the second and fourth dorsal setae, and non 'H'- or 'M'-shaped costae on anterior dorsal plate. However, the new species is distinguished from them by four pairs of perigenital setae in female, the relatively anterior location of gland pores on posterior dorsal plate, and three ventral spines on the tibia of leg II. We describe the new species herein, with detailed illustrations under a differential interference contrast microscope. We also make some brief comments on the affinities between the congeneric species of the microrhyncha group and the new species, based on a tabular key to species of the group.

Three oxytrichid ciliates, Oxytricha lithofera Foissner, 2016, Pleurotricha curdsi (Shi et al., 2002) Gupta et al., 2003 and Sterkiella tetracirrata Kumar et al., 2015, were isolated from soils and confirmed as new to South Korea. Oxytricha lithofera was identified based on lithosomes, cortical granules, 21-33 adoral zone membranelles, one left (14-21 cirri) and one right (15-18) marginal rows and 5 transverse cirri. Pleurotricha curdsi was identified based on the possession of 2 macronuclear nodules, 2-3 micronuclei, 46-53 adoral zone membranelles, 3 frontal cirri, 5 frontoventral cirri, 5-7 postoral ventral cirri, 2-3 right marginal rows and 5 transverse cirri. Sterkiella tetracirrata was identified with respect 4 macronuclear nodules, 3-6 micronuclei, 25-40 adoral zone membranelles, 3 frontal cirri, 3 postoral ventral cirri, 2 pretransverse cirri, one left (21-30 cirri) and one right (24-30) marginal row and 4 transverse cirri. On the basis of 18S rDNA sequence analyses, we describe the phylogenetic positions of the three species.
