of Ihe intervals. Whorls of llie spire angular by the prominence 

 of the middle beaded cord. Whorls 6. 



Alt. 11, diam. 13 mm. 



Hirado, Hizeu (Y. Hirase). 



Seems to agree with C. mlcrodon except in coloration, greater 

 number of spiral cords and other characters given above, but will 

 probably be considered a separate species eventually. From the 

 Polynesian C. atrojmrpweits, which von Martens reports from the 

 Mergui Archipelago, it is distinct in sculpture, etc. 

 Clanculus hizenensis n. ?p- 



Shell turbinate, moderately solid, alternately whitish and dark 

 brown in broad radial flames above, whitish profusely speckled 

 with olive-brown beneath. Sculpture of four coarse, spaced, 

 beaded, spiral cords above, separated by intervals of their own 

 width, sharply and densely striate by the growth-lines; the base 

 with 9 much smaller, closer, concentric cords, slightly cut by 

 obliquely radial grooves, the outer cord larger. Whorls nearly 6, 

 the last rounded at the periphery, slightly convex beneath. Aper- 

 ture oblique, rounded, the outer lip usually weakly plicate Avithin 

 in fully mature shells; columella having a weak fold above, and 

 inserted on the right side of the umbilicus, terminating below in a 

 strongly projecting, simple, tooth-like fold. Marginal rib of the 

 umbilicus having a few weak nodules. 



Alt. 7, diam. 7.5 mm. 



Hirado, Hizeu (Mr. Y. Hirase). 



Closely resembles the more plain-colored specimens of C. Thomasi 

 Crosse, from New Caledonia, but the spirals above are less unequal, 

 more strongly beaded and more spaced, with sharply striate inter- 

 vals. It is a somewhat larger shell than C. Thomasi. Sometimes 

 one or two of the spaces between the cords of the upper surface 

 bear a minute thread. 

 Euchelus ruber A. Ad., var. brunneus n. v. 



Shell similar to E. ruber, but dull brown or fleshy brown, with 

 scattered brown dots. 



Alt. 6i, diam. 6 mm. 



Hirado, Hizen. 



Similar to E. ruber in sculpture, but as all the Japanese speci- 

 mens I have seen are diflerent in color, it is probably distinguish- 

 able as a dull-colored race.
