This subspecies appears to occupy the territory adjacent to the south 

 side of Samana Bay, Dominican Republic. 



It is large, flesh-colored, with the peristome rayed with brown, the 

 outer lip very strongly expanded, almost forming a hood at the posterior 

 angle ; it is a little narrower on the parietal wall. 



The specimen figured (U.S.N.M. No. 5041 13) was collected on the 

 Boca del Infierno by Gerrit S. Miller, Jr. It has 4.5 whorls, the last one 

 of which bears 38 of the lamellar ribs and 6 spiral threads between the 

 summit and periphery, 3 on the base, and 7 on the umbilical wall. The 

 suture is deeply channeled. It measures: Height, 6.8 mm.; greater di- 

 ameter, 12.8 mm. ; lesser diameter, 8.9 mm.

Plate 25, Figures 1-3 



. This is a large race, flesh-colored, with the outer peristome very 

 broadly conspicuously rayed, whose axial threads between the lamellar 

 elements are considerably heavier than in the others. 



The type (U.S.N.M. No. 5041 17) was collected by Dr. Lagai at 

 "Santo Domingo," probably Santo Domingo City, and has 59 of the 

 lamellar axial ribs and bears 10 spiral cords on the last whorl between 

 the summit and the periphery, 6 on the base and 7 on the umbilical wall. 

 It has 4.5 whorls and measures: Height, 7.8 mm.; greater diameter, 

 12.2 mm. ; lesser diameter, 8.6 mm. 



U.S.N.M. No. 5041 18 contains 47 topotypes from the same source.
