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 first zoea of Pugettia gracilis is described and illustrated for the first time. Its morphological characteristics are compared with those of other known species of the genus from the northern Pacific waters. Although the Pugettia zoeas of the northwestern and the northeastern Pacifies are very similar, they can be easily distinguished by their dorsal carapace spine. In the northwestern Pacific it is spinulate with a spinous tip, while in the northeastern Pacific it is smooth with a blunt tip.

The megalopae of Pugettia quadridens quadridens (De Haan, 1850), P. quadridens intermedia Sakai, 1938, and P. marissinica Takeda and Miyake, 1972 were obtainded in the laboratory. They are described and illustrated in detail. The megalopal morphology of these three Pugettia species in compared with other Epialtinae megalopae. P. marissinica is quite ditterent from P. quadrides intermedia and P. quadridens quadridens. P. quadridens intermedia and P. quadridens. quadridens are very closely resemble to each other.

The first zoeae of Hyastenus elongatus (Ortmann, 1893) were obtained in thelaboratory from hatching. They are described, illustrated in detail and compared with the previously described zoeae of the subfamily pisinae. The zoeae of H. elongatus are similar to, but may be distinguished from those of Hyastenus diacnathus (De Haan, 1839), by the number of setae on the postero-lateral carapace margin and mouthpart appendages, and the length of a dorsal carapace spine. In the mouthpart appendages, the difference in the number of setae on an endopod of the maillule between H. eleongatus and H. diacanthus is doubtful, and it should be necessary ot make a detailed re-description of H. diacanthus.

This paper documents the defining morphological characteristics of the larval stages of Chionoecetes tanneri Rathbun, 1893, the grooved Tanner crab, from specimens reared in the laboratory. Chionoecetes tanneri larval stages include two zoeae and one megalopa. The first zoea is characterized by: six setae on the posterior margin of the carapace; postero-lateral spines on abdominal somites 3 and 4, extending beyond the posterior margin of adjacent somites and bearing 9-10 spinnules; 12 plumose setae and one stout distal plumose seta present on the margin of the scaphognathite of the maxilla; and one fused lateral spine and one articulated dorso-medial spine on each fork of the telson. The second zoea is characterized by: 9 setae on the postero-lateral margin of the carapace; a serrated mandible molar; a mandibular palp bud; 25-26 plumose setae on the margin of the scaphognathite of the maxilla; pereiopods with well-developed gills and buds; and four pairs of stout setae on the posterior margin of the telson. For the megalopal stage, the distinguishing characteristics include: a rostral spine equal in length to the supraorbital spine; six setae on the exopod of the uropod; and a single spine on the ischium of the second pereiopod. This study allows C. tanneri larvae to be distinguished from the larvae of known sympatric congeners. This information provides a basic taxonomic tool for researchers in fisheries management and zooplankton ecology who are addressing issues related to trophic interactions, metapopulation dynamics and ecosystem impacts in the evolving marine resource management strategies in the North Pacific, and those related to Chionoecetes species in particular.
