Report on the two subfamilies Clavatulinae and Cochlespirinae (Mollusca : Neogastropoda : Turridae) from the China seas

Based on the materials deposited in the Marine Biological Museum of the Chinese Academy of Sciences, Qingdao, the present paper reports ten turrid species belonging to six genera of subfamilies Clavatulinae and Cochlespirinae, including two new species, i.e., Comitas parvifusiformis sp. nov. and Leucosyrinx mai sp. nov., and three species newly recorded from China seas, i.e., Makiyamaia coreanica (Adams and Reeve, 1850), Turricula sumatrana (Thiele, 1925) and Nihonia santosi Shuto, 1969. Comitas parvifusiformis sp. nov. was collected from South China Sea in the depth of 42-75 m, which differs from the similar species C. fusiformis (Hutton, 1877) by the stronger spiral sculpture; Leucosyrinx mai sp. nov. is a deep sea species, collected from Nansha Islands in the depth of 1241 m, which can be distinguished from the close species L. julia Thiele, 1925 by the spire whorls sharply carinated at the middle of each whorl
