中文摘要：经研究发现 ,中国鲎幼体阶段 (黄皮鲎 )生殖盖板中叶不长于侧叶 ,尾呈三角形 ,上有一列小刺 ,腹甲后端尾上有三个棘突 ,尾两下侧边无小刺 ,腹甲背面无小刺分布 ,但其头胸甲和腹甲背面棘突较长 ,明显呈幼体状。中国鲎的胚后幼体发育从小到大 ,身体背部颜色处于黑色→土黄色→褐色的一种渐变过程。当中国鲎幼体头胸甲宽度处于 10～ 2 5cm时 ,也就是胚后发育的第 12至第 16次蜕皮期间时 ,其体色呈土黄色 ,在粤西、海南、北部湾一带俗称“黄皮鲎”。所以 ,黄皮鲎为中国鲎一定阶段未成熟的幼体 ,而不是一个新种或亚种。标本采自广东省湛江市 。

外文摘要：The North gulf and Leizhou gulf in the northern of the South China Sea is situated between 107.5°～111° E and 20°～21.7° N latitude with high temperature and a large quantity of rainfall, which belongs to oceanic climate of the torrid zone and subtropical zone. From August 1997 to August 1999, We studied the morphology of sallow horseshoe crab in the North gulf and Leizhou gulf. We found the juveniles of Tachypleus tridentatus including zooids with different sizes from 10 cm width of prosoma to 25 cm. These juveniles of Tachypleus tridentatus were called sallow horseshoe crab in the west of Guangdong province, Hainan, and the North gulf regions because of the sallow body colour. The morphology was studied in the sallow horseshoe crab by observation and comparison with other horseshoe crab. We found that the body colour of sallow horseshoe crab was yellowish brown, and its body size was small. Its middle leaves of reproductive operculum was not longer than lateral leaves. Its tail was triangular in shape, on which there was a row of little thorns. On the end of opisthosomatic carapace there were three immovable spines. There were no little thorns under two lateral ridge of its tail and on the opisthowomatic carapace, and its opisthowomatic carapace immovable spines were much longer. We also found that the back colour of body of Tachypleus tuidentatus was gradually changing from black to sallow to brown during post-embryonic development from the first instar stage to adult. When the width of prosoma of juveniles of Tachypleus tridentatus was 10～25 cm that is in the 12～14 instar stages of post-embryonic development, the colour of its body was sallow. All these suggested that sallow horseshoe crab was immature Tachypleus tridentatus, not a new species or subspecies. The specimens were collected from Zhanjiang, Guangdong Province, and were preserved in the Museum of Aquatic Biology of Zhanjiang Ocean University.
