BRACHYPODELLA, S. STR. 87 



angular below, its later half free, pinched into a strong, stout 

 basal keel, concave on both sides of the keel, narrowly swollen 

 at the periphery, flattened above ; projecting and slightly de- 

 scending. Aperture oblique, rounded, but a little angular at 

 the base and outer margin, the lip white and reflexed. Axis 

 simple and slender. 



Length 7.6, diam. 2 mm., whorls 9% (truncate). 



Length 6, diam. 1.6 mm., whorls 8 (truncate). 



Length 5.7, diam. 1.4 mm., whorls 8 (truncate).

The smallest species known from the island, readily recog- 

 nized by its strong sculpture and angular neck. 



36a. Yar. gabbi Pils., n. var. (pi. 8, fig. 56) . Larger, with the 

 neck somewhat longer and decidedly descending. Truncate. 

 Length 9.3, diam. 1.8 mm., whorls lO 1 /^ to length 8, diam. 1.8 

 mm., whorls 8%. The riblets are perceptibly enlarged at the 

 ends, and sometimes hollow or with a minute pit there. Were 

 it not that the specimens were taken in Santo Domingo by 

 Gabb, they would hardly be separated from B. chordata of 

 St. Croix.
