The zoea1 stages of Philyra kanekoi Sakai, 1934 were obtained by laboratory rearing. Three zoeal stages were described and illustrated in detail. Zoeal morphology was compared with those of other described species of the family Leucosiidae. Morphological comparisons with congeneric species revealed that zoeas of P. kanekoi were more similar to those of P. pisum and P. platychira than to other Philyra. The present material could be distinguished from other Philyrinae species by having no dorsal carapace spine, a spinous tip of the antenna, and no chromatophore on the base of a dorsal carapace spine. Within the family Leucosiidae, the zoeas of three Philyra (P. kanekoi, P. pisum and P. platychira) showed the greatest affinities with Leucosia sima and L. pubescens (Leucosiinae), and the number of setae on the basipod of the first maxilliped could be very useful characterisitcs for indentification between Philyra and Leucosia zoeas.

The first zoeas of Nursia rhomboidalis and Pyrhila carinata were obtained from laboratory condition. They are described and illustrated for the first time. Morphological comparison with those of other Korean described species of the family Leucosiidae reveals that the zoea of N. rhomboidalis is very similar to those of Myra fugax and Arcania undecimspinosa based on characteristics of the carapace spines length, the antenna morphology, the maxilla endopod setation, and the telson, whereas, the zoea of Py. carinata coincides well with those of Philyra kanekoi and Pyrhila pisum based on characteristics of the carapace spines length, the antenna morphology, the maxilla endopod setation, and the telson. Furthermore, we find that at least two groups of zoeas exist in the Korean species of the subfamily Ebaliinae. A provisional key to the known zoeas of ten leucosiid species from Korean waters is provided.

The leucosiid crabs are common species on soft sediment from the intertidal flat to shelf and slope depths. The genus Nursia Leach, 1817 is characterized by the pentagonal shape of the carapace and the presence of the buccal cavern on the pterygostomian region. As a result of the systematic study on the Korean brachyuran species, Nursia rhomboidalis (Miers, 1879) is newly recorded in Korean fauna. Korean Leucosiidae is now composed of 14 species belonging to eight genera. The description and illustrations of this species are provided.

실험실에서 사육된 밤게의 유생은 2조에아 유생기와 1메가로파 유생기를 가졌고, 조 에아 유생기를 완전발생 시키는데 $25^{\circ}C$ 수온에서 최저 11일이 걸렸다. 각 유생기의 형태적 특징을 상세히 기재 및 도시하였다. 밤게의 제1조에아 유생은 갑각에 아주 짧은 액극을 가 지고 배극이 없다는 것을 제외하고는 그 외의 모든 특징에서 이미 알려진 밤게 속의 다른 유생과 잘 일치하고 있었다. 밤게가 속하고 있는 subfamily Philyrinae의 조에아 유생은 그 특징에 의거 Arcania septemspinosa, A. undecimspinosa elongata, 긴손밤게(Myra fugax)을 포함한 군과 Philyra corallicola, 납작손밤게(P. syndactyla), 밤게(P. pisum)을 포함한 군으 로 나눌 수 있다.

Leucosia anatum, also known as the pebble crab, is a species of crab that belongs to the family Leucosiidae. Crabs are the most conspicuous and abundant components of the epibenthic macrofauna of the mangrove ecosystems. The present investigation was carried out with the objective of enlightening the reproductive system of L.anatum through histological and histochemical studies. Histological analysis of the epithelial cells of vas deferens, the luminal size and shape of the vas deferens was carried out, since the spermatophore material is secreted and molded by the vas deferens. Histochemical analysis of the blood plasma, testis, proximal vas deferens, middle vas deferens, distal vas deferens, seminal plasma and spermatophore was done to reveal the possible transformation of their secretory materials into the spermatophoric components. Biochemical components present in the blood plasma, testis, proximal vas deferens (PVD), median vas deferens (MVD) and distal vas deferens (DVD) regions seminal plasma and spermatophore of pebble crab were analyzed to find out the quantity of free sugars, proteins, and fats. Thus the current study focuses on the histological and histochemical analysis of Testis and Vas Deferens and their secretions in L.anatum.
