164 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



Specimens in the United States National Museum, including the 

 species now under review. Examples of the allied D. leucocyma?- 

 Dal], and zehra, Lam., accompanied this from the island of Cuba, 

 and are in Mr. Sykes' collection. Also two of the Orbignyan 

 species, D. ornata and albomaculata.^ 



I have unusual pleasure in having the opportunity of naming this 

 species after an island which I visited many years ago — ^in March, 

 1872 — where a most happy and enjoyable time was spent in 

 what is, perhaps, the most beautiful, as it is the largest, of the 

 West Indies. 



Drillia euphanes, n.sp. (PL IV, Fig. 4.) 



Shell fusiform, rather solid, white ; whorls 8, of which two are 

 nuclear, globular, white, smooth, the remainder suturally impressed, 

 with regular incrassate nodulous longitudinal ribs, bluntly angled 

 at the periphery, the nodules large, shining. The ribs on the body- 

 whorl number eight or nine. These are crossed by somewhat coarse 

 revolving lines, which, in the specimens before us, are nearly obsolete. 

 Mouth roundly-ovate, sinus rather wide and deep, outer lip slightly 

 expanded, columellar margin fairly straight, canal very short. 



Long. 12, lat. 5 mm. sp. maj. ; long. 9, lat. 4 mm. sp. min. 



Hah. — Cuba. 



Dr. Dall informs me that similar shells m the United States 

 National Museum are labelled fucata, Reeve,^ but these are 

 unauthenticated, and the name is therefore very doubtful. This 

 Antillean species is larger, say 20-21 mm. in length, but much of 

 the same character as to its ribs and general appearance. It is, 

 however, channelled above the periphery, and the coloration is" 

 yellowish-white, with brown maculations. D. paria, Reeve,* may 

 also be compared, {evipdvrji of good appearance.) 



" Drillia innocens, n.sp. (PL IV, Fig. 5.) 



Shell fusiform, very smooth and shining, somewhat lightly 

 built, pure white; whorls 7-8, of which the nuclear (two) are 

 smooth and globose, the remainder all suturally impressed, with 

 numerous irregularly formed longitudinal incrassate ribs ; the rest 

 of the surface smooth and plain. Mouth rather wide, ovate, outer 

 lip thin, to some extent expanded, sinus situate directly below the 

 suture, wide, columellar margin straight, canal very abbreviate. 



Long. 14, lat. 6 mm. sp. maj. ; long. 9, lat. 3"5 mm. sp. min. 



Hah. — Cuba.
