This species is intermediate between Clathrodrillia and some of the 

 species of Surcula., but on the whole is nearer the former by its sculp- 

 ture and the latter in its straight canal. 



CLATHRODRILLIA CALLIANIRA, new species. 



Plate 5, fig. 2. 



Shell slender, acute, pale brownish, with a smooth i^egularly in- 

 creasing nucleus of two and a half whorls and eight and a half sub- 

 sequent whorls ; suture closely appressed with a cord-like edge behind 

 the strongly constricted, arcuately striated anal fasciole; spiral sculp- 

 ture of (on the penultimate whorl about seven) flattish, close-set 

 cords; in some specimens these alternate in size, in others they are 

 nearly equal; on the last whorl there are about 25, some irregularly 

 larger than the others, and a few smaller threads on the canal ; axial 

 sculpture of (on the last whorl 10 to 14) rounded ribs with subequal 

 interspaces, more conspicuous and less numerous as we ascend the 

 spire, over which the spiral sculpture passes without nodulation; 

 aperture short, subovate, anal sulcus short rounded, with a subsutural 

 callus; outer lip arcuate, thin, smooth inside, without any marked 

 varix behind it; inner lip and pillar with a smooth callus; canal 

 short, slightly recurved. Height of shell, 16; of last whorl, 8.5; 

 diameter, 5.5 mm. Cat. No. 96722, U.S.N.M.

 meter; suture closely appressed, obscure, bordered in front by two 

 undulated cords, the anterior cord larger; axial sculpture of (on the 

 last whorl 18) equal narrow nodulous ribs with subequal interspaces,
