ABT. 18 SMALL SHELLS DREDGED BY " ALBATROSS '' DALL 59 



Genus UROSALPINX Stimpson 



There is a group of small deep water shells referred by Verrill to 

 this genus, to which they bear a certain resemblance, but of which 

 the dentition and other anatomical characters are as yet unknown. 

 To this belong U. carolinensis and U. macra Verrill, and apparently 

 the following species. I confess to doubt as to their proper place and 

 whether they really belong to the genus typified by U. cinereus Say, 

 but in advance of further information it seems best to leave them, 

 tentatively, where Verrill placed them. 



7 UROSALPINX VERKILLI, new species 



Shell small, white, fusiform, with a smooth white nucleus of about 

 one smooth small whorl followed by a second minutely reticulate 

 whorl, on which the spiral threads are stronger, increasing in strength 

 to the end of the nuclear portion, and three subsequent well rounded 

 whorls; suture distinct and deep, not appressed; axial sculpture of 

 (on the last whorl about 15) narrow rounded ribs crossing the whorls, 

 with wider interspaces; the incremental lines are fine even, closely 

 adjacent, and of a silky texture; the ribs are obsolete on the base of 

 the last whorl; spiral sculpture of (on the penultimate whorl 6; on 

 the last whorl 11) equal and equally spaced rounded cords with sub- 

 equal interspaces (in which occasionally some fine spiral striae occur) 

 and 10 or more close-set simple cords on the base; the former are 

 slightly swollen at their intersections with the ribs; aperture semi- 

 lunate, the outer lip thin, smooth internally, the body erased, the 

 pillar short, twisted, the canal short and recurved; the axis impervi- 

 ous. Length of shell, 9; of aperture, 4.5; diameter, 4.5 mm. U. S. 

 Nat. Mus. Cat. No. 108319. 



Off Georgia, abundant. 



? UROSALPINX STIMPSONI. new species 



Shell small, fusiform, white, with an inflated, smooth white nucleus 

 of a whorl and a half and nearly four subsequent whorls; suture 

 distinct, rather deep, whorls well rounded; early whorls more or less 

 distinctly ribbed with about 16 rounded ribs on the penultimate 

 whorl, obsolete on the last whorl, with more or less obvious close 

 incremental lines; spiral sculpture of (on the penultimate whorl 6; 

 on the last whorl about 20) equal and equally distributed cords with 

 usually wider interspaces in each of which runs a fine intercalary 

 thread; this sculpture covers the whole whorl; aperture sublunate, 

 outer lip thin, sharp, crenulate by the sculpture; body lightly erased, 

 pillar smooth, twisted; canal short, slightly recurved; axis pervious. 

 Length of shell, 10; of aperture and canal, 4.5; diameter, 6 mm. 

 U. S. Nat. Mus. Cat. No. 107999.
