| 摘要: |
| 本文记述中国海织纹螺科两新记录种。研究材料来自中国科学院海洋研究所历年来在中国沿海采集的织纹螺科标本, 通过外部形态和齿舌解剖比较研究, 鉴定出属于织纹螺属Nassarius的2个中国新记录种: 厚唇织纹螺Nassarius biendongensis Kool, 2003和佳美织纹螺Nassarius euglyptus Sowerby, 1914。它们分布于中国的东、南部沿海, 前者栖息于潮间带中、低潮区的泥沙质海底; 后者栖息于潮下带, 垂直分布在水深10—200m左右的泥沙或软泥质海底。 |

| Abstract: |
| This paper deals with two new records species of Nassarius (Gastropoda, Nassariidae), based on the Nassariidae specimens deposited in the Institute of Oceanology, Chinese Academy of Sciences which collected in the Chinese coastal areas and Nansha Islands waters over the past years. Through the morphology and radular anatomy comparative studies, the two new records were identified belonging to genus of Nassarius: Nassarius biendongensis Kool, 2003; and Nassarius euglyptus Sowerby, 1914. The two new recorded species distributed in the East China Sea and South China Sea. The former one lives in the muddy sand bottom in the mid-tidal and low-tidal of intertidal zone, and the latter one mainly lives in the mud or muddy sand bottom in 10—200m depth. In this paper, the morphological characteristics, ecological habits and geographical distribution of the two new recorded species were studied, and comparisons were made between N. euglyptus and the similar species N. crematus. N. euglyptus with three brown bands on the body whorl, but the N. crematus with dark-brown bands in the dorsum, the body whorl more inflate, the inner lip callus expended towards body whorl, and usually cover the columella. On columellor lip are developed colllumellor folds. These characters may be used to discriminate the two similar species. |
