摘要
1975年4月,我所崔玉珩同志从黄海北部水深72米处采泥时,采得两个带两碎片的小的楯海胆标本。通过作者仔细研究鉴定认为:这小的楣海胆代表一个新属,现将这个新属描述如下:中华扣海胆(新属)Sinaechinocyamus new genus鉴别特征小形种,壳低平,边缘薄,轮廓为不规则的圆形;口面平,反口面稍拱起;顶系明显在前方,具4个生殖孔;瓣短,末端开口;孔对不相连;瓣板全部是简单的初级板;后区间步带不连续,前对间步带稍连续;间步带顶端和顶系相接处为一对小板;围肛部显然上缘位;口面步带沟不明显;耳状骨愈合;内隔壁简单;反口面大棘棒状;小棘稍呈冠状,顶端有点扩大和倾斜。
In April 1975,through the kindness of my colleague Comrade Cui Yuheng,a couple of specimens with two other fragments of specimens of small clypeasteroid sea-urchin were sent to me for identification.They were obtained by the grab in the northern Huang Hai(Yellow Sea)at a depth of 72 meters.Careful examination showed that this small clypeasteroid sea-urchin represents a new genus,the description of which is given below.
