 (St. Martin). 



Pfeiffer's original description is given above, and figs. 8, 11 

 represent specimens from Vieque, the type locality. Shells 

 from St. Martin and St. Barts (figs. 6, 7) are similar. 



Pfeiffer has applied the name var. minor to specimens from 

 Barbados, but no dimensions or other characters have been 

 given, and I do not see that the shells differ materially from 

 those of the northern islands. Curiously enough, they do not 

 belong to the Guadeloupe race. One is drawn in fig. 12. 



The species seems everywhere restricted to the coastal belt 

 of elevated coral reefs, where the snails subsist upon lichens 

 or fungi growing on the limestone. The radula of an indi- 

 vidual from St. Barts (pi. 1, fig. 13) has the formula 6.2.1.2.6. 

 That of the more strongly carinate form (schrammi) from 

 Guadeloupe (pi. 14, fig. 7) has 5.2.1.2.5 teeth, very similar in 

 form. I found the radula of an individual from St. Martin 

 to be the same; so I am somewhat inclined to think that fig- 

 ured by Binney was abnormal in the greatly reduced size of 

 the median three teeth. 



Var. schrammi (Fischer). PI. 1, figs. 1, 2, 5. 



The specimens from Guadeloupe are somewhat wider, more 

 conic, the last whorl more strongly carinate, and the keel is 

 more distinctly and coarsely serrate or tuberculate. While 

 some individuals from St. Martin and St. Barts approach this 

 form, yet there is in the average a noticeable difference, which 

 may properly be recognized in nomenclature. Figs. 1, 2 are 

 copied from the original illustrations of schrammi; fig. 5 was 

 drawn from a Guadeloupe specimen.

 corneous, obscurely variegated with oblique whitish streaks.
