A. Adams's type came from Japan. The above description is based 

 upon two individuals from a lot of four, U. S. National Museum col- 

 lection, No. 170808, which come from Hirado, Hizen, Japan. The 

 nucleus was described from one specimen and the post-nuclear charac- 

 ters from the most perfect individual in the collection^ which belongs 

 to the same lot; this has sixteen post-nuclear whorls, and measures: 

 long. 17, mm.; diam. 4.5 mm. This specimen is a little more slender 

 than the average individual. One, having fourteen post-nuclear whorls, 

 measures: long. 14.2 nun.; diam. -4.3 mm. Some show five well-devel- 

 oped, subequal and subequally spaced interrupted lirations on the 

 outer lip. The line spiral striations are quite superficial and do not 

 appear on specimens which are somewhat worn. There are two other 

 specimens, No, 180076, in the U. S. National Museum from pJapan. 

 Gould's type of Ohellscus huxeus is from the China Seas ; it is an immature 

 shell of ten post-nuclear whorls and is registered as No. 389. A speci- 

 men received from Eastlake, No. 160684, was collected at Hongkong, 

 China. The Berlin collection contains one worn and bleached indi- 

 vidual which is lacking a number of the early post-nuclear whorls. 

 It was labeled Oheliscux htcolor Menke, California, which of course is 

 an error. O. hlcolor is a triplicate spevies= Pi/rai/iidena {Longchaeas^ 

 hicolor Menke. 



PYRAMIDELLA (IPHIANA) LISCHKEI, new species. 

 Plate XXV, fig. 1. 



Shell slender, elongate-conic, subdiaphanous, polished, girdled by 

 two golden-yellow bands between the sutures. Nuclear whorls decol- 

 lated. Post-nuclear whorls rather high between the sutures, very 

 slightl}" shouldered and well rounded, marked b}' rather strong lines 

 of growth and scarcely visible closely placed spiral striations. The 

 posterior band lies somewhat posterior to the middle of the whorl, 

 while the anterior one is somewhat posterior to the periphery, showing 

 therefore, on all the whorls a little above the well-marked suture. 

 Periphery of the last whorl well rounded. Base attenuated. Aper- 

 ture su])oval, posterior angle acute, outer lip slightly expanded ante- 

 riorly, without internal lirations, columella reenforced by the attenu- 

 ated base, and almost enveloped by it, bearing a moderately strong, 

 obli(|ue fold near its insertion; parietal wall covered by a thin callus. 



The specimen described above belongs to the Pwtel collection and 

 comes from Japan. It has eight post-nuclear whorls, and measures: 

 long. 4.6 mm.; diam. 1.4 mm.
