AKT. 18 SMALL. SHELLS DREDGED BY *' ALBATROSS ' ' DALL 73 



the characters agree well with those of Mucronalia, and it seems best 

 to place it tentatively with that group. 



Genus STILIFER Broderip 



STILIFER VERRILLI, new species 



Shell small, inflated turbinate, white, polished, with a minute styli- 

 form apex and about three globose rapidly enlarging whorls; suture 

 appressed, distinct, not deep; sculpture of very faint incremental lines, 

 and a slight wrinkling along the anterior edge of the suture; base 

 imperforate, rounded, aperture ample, outer lip thin, inner lip some- 

 what thickened. Length, 4; diameter, 3.5 mm. U. S. Nat. Mus 

 Cat. No. 108111. 



Off Fernandina, one specimen. 



At first sight this would be taken for a mutation of S. stimpsoni 

 Verrill, but the second whorl is much smaller than in that species. 



The last whorl comprises most of the shell. 



STILIFER MINIMA, new species 



Shell minute, turbiniform, thin, white polished, with a minute styli- 

 form brownish nucleus of two and about three subsequent inflated 

 whorls; suture very distinct, rather deep; sculpture only of extremely 

 faint incremental lines; base plumply rounded, imperforate; aperture 

 wide, semilunate, the margins thin and sharp. Length of shell, 3; of 

 aperture, 1.4; diameter, 1.9 mm. U. S. Nat. Mus. Cat. No. 108039. 



Off Fernandina, four specimens. 



STILIFER MINUTA, new species 



Shell minute, transparent, thin, with a minute styliform brownish 

 nucleus of about three, and three subsequent whorls; suture distinct, 

 narrowly appressed; surface with faint incremental lines but no other 

 sculpture; the general form is like a short Bulimulus; the last whorl 

 about three-fifths of the whole shell; base rounded; aperture semilu- 

 nate, the margins thin, the inner lip a Uttle raised but with no indi- 

 cation of an umbilical dimple. Length, 2; diameter, 1.7 mm. U. S. 

 Nat. Mus. Cat. No. 108227. 



Off Fernandina, one specimen. 



This resembles S. minima but is smaller and proportionately more 

 globose. It is the smallest species I have seen. 



Family PYRAMIDELLIDAE 



This family is well represented in the collection by 24 species, all 

 supposed to be new, but very unequally represented at the two sta- 

 tions. Off Fernandina 19 species and 250 specimens were obtained, 

 but of these 194 specimens represented only 4 species. Off Georgia 

 only 30 specimens of 8 species were obtained. Only 3 species, total-
