  • 실험실에서 사육된 눈콩게의 전 유생발생단계를 기술, 도시하였다. 눈콩게는 5 zoea(가끔 6 zoea)와 1 megalopa유생기를 가졌다. 수온 $25^{\circ}C$에서, megalopa와 제1기 carb 부화후 각각 24일과 38일만에 나타났으나 extra zoea유생기를 갖는 경우에는 31일과 48일만에 나타났다. 눈콩게의 zoea유생 거치상의 갑각가시와 배측에 하나, 복측에 두 개의 작은 가시가 있는 미절에 의하여 엽낭계속의 타종과 구분되며, megalopa 유생은 갑각의 특징에 의하여 구분될 수 있다. 그 밖의 미세한 형태적 특징들이 앞서 보고된 엽낭개속의 유생들과 비교되어 차이점이 간단히 논의되었다.

  • The author colelcted crabs (Tribe Brachyura ) on the coasts of fourteen western islands of South Korea (Paenyong Do, Taechong Do, Sochong Do, Taeyonpyong Do, Kanghwa Do, Yongjong Do, Chagyak Do, Tokchok To. Moktok To. Pukkyoknyolbi Do. Ong Do, ANmyon Do, Pigum Do, and Taehuksan Do) mainly in summers during a period ranging from 1955 to 1962. Of these Islands, Paeknyong , Taehong, Taeyonpyong, Ong, Anmyon, Pigum and Taehuksan Do are the localities where the crabs were investigated firstly by the present author. The collections made by the author consist of 1779 specimens of crabs involving 9 families. 25 genera, 33 species and 5 subspecies (Table2). 23 species of crabs had been reported hitherto from Tokchok To and 7 from Kanghwa Do. In present paper the author adds 1 species to the fauna of crabs of Tokchok To and 7 to that of Kanghwa Do. In present paper the author adds 1 species to the fauna of crabs of Tokchok To and 7 to that of Kanghwa D. Among 38 species or subspecies of crabs collected, Oregonia gracilis, Cancer amphioetus and Chaesmagnathus convexus are new to the fauna of the west coast of Korea. 57 species of crabs are therefore identified in this area. The author collected Pinnotheres cardii on Taechong Do and Scopimera bitympana on Pigum Do. It became, therefore, clear that these two kinds of crabs occur much wider areas than known hitherto in Korea. The nothern limit of the distribution of Ocypoda stinpsoni and Sesarma haematocheir is Kyungki Bay as known already, that of Helice tridens is ,however, more northern part than Kyungki Bay, since they were collected on Paeknyong Do.
