The first zoeal stage of Macromedaeus orientalis (Takeda et Miyake, 1969) is described and illustrated. Its morphological characteristics are compared with those of other known species of the subfamily Xanthinae. The first zoeas of M. orientalis and M. distinguendus are similar, but they can be distinguished from each other by the characteristic of antenna. The former has a smooth antenna with a rounded tip, while the latter has a serrated antenna with a spinous tip.

Pagurus lanuginosus do Haan의 유생을 실험실에서 사육하며 glaucothoe기까지의 발생을 관찰 연구하였다. 1) P. lanuginosus는 4기의 Zoea기와 1기의 glaucothoe기의 유생기를 가졌다. 2) 평균 수온 $13.6^{\circ}C$와 평균 염분농도 $33.67\%_{\circ}$의 사육조건에서 알에서 부화한 zoea유생은 31-32일 후에 glaucothoe 유생으로 변태 발생했다, 3) 각 zoea기의 평균기간은 7-9일이었다. 4) zoea 유생의 가장 독특한 형태적 특징의 하나로 미선(telson)의 말만에 3쌍의 들기(1쌍의 털과 6쌍의 침)를 가지며 그 돌기의 수와 모양은 전 zoea기 동안에 변함이 없다. 5) zoea 유생의 제2 촉각의 외지의 내변에는 5개의 우상모가 나 있다. 6) glaucothoe 유생의 telson 말단에는 3쌍의 우상모가 나 있다. 7) glaucothoe 유생은 안병극을 갖지 않는다.

실험실에서 사육된 애기털보부채게의 유생은 4 zoea 유생기를 가졌고, zoea 유생기를 완료하는데 25$^{\circ}C$ 수온에서 최저 15일이 걸렸다. 각 zoea 유생기의 형태적 특징을 상세히 기록, 도시하고 Pilumnidae과의 이미 보고된 다른종의 제 1 zoea유생과 그 특징을 비교하였다. 애기털보부채게는 구부부속지나 갑각극의 형태적 특징에서 Pilumnus 속의 다른 종들과 차이가 없었으나 복부측돌기는 복부 제 2, 3, 4, 5절에 존재하므로 Pilumnus 속의 다른 종들과 형태적 차이를 보이고, 이 특징은 세가지 부채게에서 볼수 있는 복부의 형태적 특징으로 두종간에 어떤 유연관계가 있는 것 같다.

An ovigerous hair crab, Telmessus acutidens, was collected in South Korean waters and its larvae were reared in the laboratory. The larval development consists of four zoeal (including an extra zoeal stage) and one megalopal stages. Four zoeal stages are described and illustrated in detail. The zoeas of the present material show some differences from Kurata (1963)'s plankton-collected zoea of T. acutidens in the characteristics of the carapace spines, an endopod and an exopod of the antenna, and the posterolateral process of the abdominal somite. Kurata's zoea agreed well with that of T. cheiragonus. So, it is suggested that Kurata's zoea may be the second zoea of T. cheiragonus.

Zoeas of Leptomithrax edwardsii were reared in the laboratory. Two zoeal stages are described and illustrated. The first zoeal stage of L. edwardsii is compared with those of seven known species of the family Majidae. It differs from previous description in the endopodal setation characters of the maxillule and the second maxilliped. It appears most similar to L. bifidus and Schizophroida simodaensis of the northwestern Pacific. A provisional key for identifying eight majid zoeas is included.

The introduced spider crab Pyromaia tuberculata was collected from Korea in 2005 and it was ovigerous. After hatching, larvae were reared in the laboratory at $20^{\circ}C$. The larval stage of the species consists of two zoeal and one megalopal stages. The larvae of the Korean species differ somewhat from those from New Zealand described by Webber and Wear (1981; N Z J Mar Freshwat Res. 15:331-383) and from Brazil described by Fransozo and Negreiros-Fransozo (1997; Crustaceana. 70:304-323.) in the setal presence of the antennule, the maxillule, the maxilla and the maxillipeds, and the abdomen. It is found that Fransozo and Negreiros-Fransozo have overlooked some setae on the basis of the zoeal maxillipeds and that re-examination of their larvae is needed. Also, it is found that the Inachoididae is heterogeneous based on the zoeal morphology because two distinct groups exist in the family.

The larvae of Scyra acutifrons are described and illustrated for the first time. The larval stage consists of two zoeal and a megalopal stages. The zoea of S. acutifrons is compared with those of other known species of the Epialtidae from the northern Pacific. The zoea of Scyra acutifrons can be easily distinguished from that of S. compressipes by having a longer rostral carapace spine and an endopod of maxillule with three setae. It is found that the genus Scyra (Pisinae) shows a great similarity to Pisoides bidentatus (Pisinae) and the genus Pugettia (Epialtinae) in the family Epialtidae; especially, S. acutidens coincides well with two Pugettia species (Pugettia incisa and P. gracilis) in the characteristics of the zoeal mouthpart appendages. To facilitate the study of plankton-collected material, a provisional key to the known zoeae of the Epialtidae from the northern Pacific is provided.

The first zoeal stage of Pagurus japonicus is described and illustrated. Its morphological characteristics are compared with of other species of the genus Pagurus. The first zoea of P. japonicus was very similar to that of P. similis. The zoeas of the two species could be distinguished from other pagurid zoeas by morphological characteristics of the carapace without posterolateral spine. two setae on the endopod of the antenna, and 3＋3 setae on the endopod of the maxilla. They show affinities more to the species of the family Diogenidae than to the species of the genus Pagurus in respect of zoeal morphology.
