NO. 2288. NEW MOLLUSKS OF THE FAMILY TURRITIDAE—DALL. 9 



lip thin, sharp, prominently produced ; inner lip erased, pillar stout, 

 short, white, obliquely attenuated in front ; canal wide, short, hardly 

 differentiated from the aperture. Height of shell, 9 ; of last whorl, 5 ; 

 diameter, 4 mm. Cat. No. 96194, U.S.N.M. 



Range. — Station 2777, in the Straits of Magellan, in 20 fathoms, 

 gravel; U. S. Bureau of Fisheries. 



The aperture of the specimen figured is defective. 



CYMATOSYRINX HECUBA, new species. 



Plate 20, fig. 9. 



Shell small, acute, rosaceous, solid, with six whorls, excluding the 

 (damaged) nucleus, differing from the preceding species by its more 

 slender shell, wider fasciole, over which the ends of the ribs reach 

 the preceding suture, forming a more pronounced shoulder at the 

 periphery, and having the whole shell spirally sculptured by small 

 equal threads with subequal interspaces. The pillar is longer and 

 the canal distinct, longer, and somewhat constricted. Otherwise 

 the shells are very similar and the nucleus, though damaged, appears 

 to have been of the same character. Height of shell, 11; of last 

 whorl, 6.5 ; diameter, 4.5 mm. Cat. 73995, U.S.N.M. 



Romge. — Gulf of California; Stearns collection. 



Thi^ was named rosacea by Carpenter in manuscript, but is not the 

 rosacea of Mighels, in 1845. The surface is polished, but that may 

 be due to wear, as it is evidently a beach specimen. The aperture is 

 incomplete in the specimen. 



ELAEOCYMA lANTHE, new species. 



Plate 4, fig. 6. 



Shell acute, polislied, white with touches of brown on the anal 

 fasciole and on the last whorl behind the varix; nucleus blunt, the 

 first whorl smooth, the second peripherally carinate; subsequent 

 whorls eight, moderately rounded ; suture distinct, appressed, some- 

 what undulate, the anal fasciole narrow, slightly constricted; spiral 

 sculpture of (on the penultimate whorl 3 or 4) incised lines in front 

 of the periphery, the wider interspaces raised and more or less 

 rounded, on the last whorl there are 16 or more, extending to the 

 canal; the incised lines have a more opaque appearance contrasting 

 with the translucent white of the whorls; there is no fine spiral stri- 

 ation; axial sculpture of (on the penultimate whorl about a dozen) 

 strong, wide ribs less prominent on the fasciole and fading out on the 

 base and the last half of the last whorl; the interspaces equal or 

 sometimes wider; the ribs are cut by the incised lines but are not 

 nodulose; they are most prominent on the anterior half of the 

 whorls of the spire and on the periphery of the last whorl ; aperture 

 narrow, anal sulcus deep and rounded, with a prominent subsutural
