  • 실험실에서 사육된 범게(Orithyia sinica) 의 메갈로파 유생을 형태적으로 기술하고, 근연과에 속한 메갈로파 유생들과 형태적인 특징들을 비교 하였다. 범게(O. sinica) 의 메갈로파기는 근연과에 속한 메갈로파들과 다음과 같은 면에서 비교 구분되었다: 갑각은 그 폭이 길이보다 약간 길며 옆으로 2개의 가시가 있고, 다섯 번째 보각의 발가락마디 끝에 긴 강모가 없으며, 꼬리는 매끈하고 그 끝이 약간 오목하였다.

Larval Development of llyoplu dentimerosa Shen, 1932 (Decapoda, Brachyura, Ocvpodidae) Reared in the Laboratory (실험실에서 사육된 털콩게 Ilyoplax dentimerosa Shen, 1932의 유생발생)

  • Larvae of Ilyoplax dentimerosa Shen, 1932 were reared in the laboratory at $25^{\circ}C$ and 33.3%o salinity. Four zoeal stages were recognized in the lanral development, and these are described and illustrated. The first soeae of 1. dentimerosa are distinguished from other llyoplax zoeae by having minute spicules on the rostral and dorsal carapace spines, a short dorsal carapace spine about half of the carapace length, a conspicuous antennal exopodite with a subterminal sutta and acute spines on the postero-lateral border of the fourth abdominal somite.

  • 농게(Ura arcuata) (달랑게과, 달랑게아과) 의 유생을 부화에서부터 첫 번째 게기까지 수온 $25^{\circ}C$ , 염분농도 33.3$\textperthousand$의 해수에서 사육하고, 각 유생기이 형태적인 특징을 기술 및 도식하였다. 이 종은 5기의 zoea와 1기의 megalopa 유생을 거쳐 첫 번째 게기로 변태하였다. 제 1 zoea 유생기는 제 1 소악의 내지에 4개의 말단강모와 제 2 악각의 기절과 내지에 각각 3개의 우상강모와 0, 0, 5 강모식을 가지고 촉각은 B형이었다. 이러한 특징들은 이미 보고된 같은 과의 유생들의 특징들과 잘 일치하고 있다.

  • 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.

  • Two species of crabs, Homola orientalis Henderson, 1888 and Pseudomicippe nipponica (Sakai, 1938), are described and illustrated for the first time in Korea. Homola orientalis was collected at 30 m depth by trap from Busan, and P. nipponica was collected on the intertidal region in Seongsanpo, Jejudo Island. Homola orientalis is the first species of its family in the region. The family Homoldae is characterized by a linea homolica on the carapace and they carry camouflage in the form of sponges or cnidarians with subchelate of the fourth ambulatory legs. The Korean brachyuran fauna now comprises 223 species including the new records from this study.
