192 BULLETIN OF THE 



Astyris profundi n. s. 



Plate XXXV. Fig. 3. 



This shell has nearly the same form as Astyris Holhollii or rosacea as figured 

 by Sars (Moll. Eeg. Arct. Norv., t. 16, fig 1), but is proportionally a little 

 wider anteriorly, and when immature has a peripheral angulation, not sharp 

 but distinct enough to be readily observed. It differs from that species in 

 (1) being more solid and strong; (2) having no transverse riblets anywhere, but 

 a very fine close spiral striation on the early whorls; (3) having a firm smooth 

 polished epidermis showing no lines of growth ; (4) having a more regular, 

 acute, and smaller apex, and less swollen apical whorls ; (5) having the outer 

 lip thickened, strengthened by a varicoid swelling, internally strongly lirate 

 with six or eight raised lirse, the inner lip with a raised callus and nine or ten 

 deeply incised grooves on the canal. The color of the deep-sea species is a 

 little more pink and its appearance more elegant owing to the polished epider- 

 mis. It averages about the same size as the C. rosacea. The specimen figured 

 is 8.0 mm. long and 3.5 mm. in maximum width. From G. diajjhana Yerrill, 

 it differs in most of the above characters as well, but especially in being still 

 broader in proportion. From a dwarf specimen of C. Saintpairiana the present 

 form would differ by its less constricted canal, more regularly ovate whorls, 

 less conspicuous varix, and especially by its less acute spire without traces 

 of ribs anywhere. The very oblique edge of the columella is extended into a 

 sharp plait, which appears to project like a tooth behind the columellar callus, 

 and, being so far up, would at first sight be taken as unconnected with the 

 pillar margin, which is masked by a false edge, in front, of labial callus. 



Habitat. Station 2, off Morro Light, Havana in 805 fms., bottom tempera-

No more specimens have turned up. The specimen figured happens to be 

 the smoothest of the lot; the more strongly sculptured specimens, taken by 

 themselves and without the connecting links, would be thought by most natu-
