Comis molis Brown and Pilsbry 



Conus molis Brown and Pilsbry, Proc. Acad. Nat. Sci. Phila. p. 343, 

 pi. 23, fig. 1, 1911. 



This large, Gatun species measures 124X71 mm. One of a 

 number of our puzzling Dominican cones very kindly examined 

 by Dr. Dall was pronounced by him to be the young of C. 

 molis. This adds another species to those common to the Isth- 

 mus and Santo Domingo. 



Locality. — (Exp'd '16) Bluff 3, Cercado de Mao. 



Conus Williamgabbi, n. sp. 

 Plate 5, Figure 2 



Shell large, solid, conic; whorls twelve, the first two nuclear, 

 the following five forming the acute apex of the spire, remaining 

 volutions of the spire very flat, each ornamented with four or 

 more revolving spiral threads and with feebler growth-striae. 

 Body whorl roundly carinated at the shoulder; upper portion 

 smooth except for almost obsolete revolving striations, lower 

 third ornamented with rather irregular, wavy spirals. Columella 

 slightly plicate. Length 65, width 45 mm. 



This fine Cone was among a number of specimens of C. hay- 

 tensis sent by Professor Gabb, but its extremely flat spire and 

 difference of form show it to be distinct. It was collected by 

 Professor Gabb in Santo Domingo and is named in his honor.
