ART. 18 SMALL SHELLS DREDGED BY ** ALBATROSS *' DALL 35 



short, attenuated in front, canal short and wide. Length, 7.4; 

 diameter, 3.5 mm. U. S. Nat. Mus. Cat. No. 108293. 



Off Georgia, six specimens. 



The sculpture varies in strength with the individual, the form 

 taken as typical is practically without ribs. 



CLATHRODRILLIA DOLANA. new species 



Shell small, whitish, with a smooth nucleus of a whorl and a half^ 

 and five subsequent moderately rounded whorls; suture distinct, 

 hardly appressed, the anal fasciole nearly smooth, hardly concave; 

 axial sculpture of (on the last whorl about 16, exclusive of the varix) 

 narrow, small, very flexuous ribs, sometimes a little angular in front of 

 the fasciole, with equal or narrower interspaces obsolete on the base; 

 spiral sculpture of (between the sutures 3) fine conspicuous threads 

 with wider interspaces, overriding the ribs; on the base and canal 

 about 10 more diminishing forward; aperture little wider than the 

 canal; anal sulcus shallow, rounded, outer lip thin, not inflected, 

 protractively flexuous; pillar short, attenuated in front; canal shorty 

 wide. Length, 6.5; diameter, 2.5 mm. U. S. Nat. Mus. Cat. No. 

 107934. 



Numerous specimens from off Fernandina. 



CLATHRODRILLIA? FANOA, new species 



Shell small, white, strongly sculptured, the aperture shorter than 

 the spire; with a smooth protoconch of a whorl and a half, and half 

 a whorl of transitional thin sharp axial riblets before the latter assume 

 the adult characters on the four subsequent whorls; suture appressed, 

 the fasciole in front of it narrow and obscure; whorls well rounded; 

 axial sculpture of 13-14 rounded ribs (on the last whorl) with wider 

 interspaces, crossing the whorls on the spire, obsolete on the base; 

 incremental hues not conspicuous; spiral sculpture of three strong 

 cords, overriding the ribs; and about a dozen smaller plain threads 

 on the base and canal; aperture rather narrow, anal sulcus very 

 shallow, outer lip sharp, protractively arcuate, thin; pillar straight, 

 somewhat gyrate but with an impervious axis; attenuated in front; 

 canal rather long and wide. Length, 7; diameter, 3.1 mm. U. S. 

 Nat. Mus. Cat. No. 107957. 



Off Fernandina, five specimens. 



SUAVODRILLIA? TEXTILIA, new species 



Shell small, vitreous white, with an inflated smooth nucleus of two 

 and four subsequent whorls; suture distinct, not constricted or 

 appressed, the fasciole in front of it conspicuous; axial sculpture of 

 well-marked incremental lines and (on the last whorl about a dozen) 

 protractively flexuous ribs with equal or wider interspaces, these are
