 measures: Length, 12.0 mm.; greater diameter, 6.1 mm.; lesser diame- 

 ter, 5.2 mm.

CHONDBOPOaiA (CHONDBOPS) BIFOEME SALABIUM, new subspeoies 



Plate 33, Figure 7 



Of this race I collected a large series at the northeastern end of the 

 salt pans on Salt Cay, south of Grand Turk Island, August i, 1930, as 

 well as at a number of additional stations on the same island. It is a 

 small race with slightly rounded whorls, feeble spiral sculpture, and 

 closely spaced, fine axial threads and crowded axial riblets on the base. 

 It recalls Chondroponw, (Chondrops) biforme neyi from Inagua Island 

 but differs from it in its much finer sculpture. 



The type (U.S.N.M. No. 536676) has 4.1 whorls remaining and 

 measures: Length, 9.0 mm.; greater diameter, 4.8 mm.; lesser diame- 

 ter, 4.1 mm. 



U.S.N.M. No. 390571 contains 465 topotypes from the same source. 



U.S.N.M. No. 391860 contains 15 specimens collected by Bartsch on 

 Salt Cay along the shore of the northeastern end of the salt pans. Salt 

 Cay. 



U.S.N.M. No. 390175 contains 5 specimens collected by Bartsch near 

 the lighthouse at the northwestern end of Salt Cay. 



U.S.N.M. No. 391854 contains 23 specimens collected by Bartsch on 

 the south end of Salt Cay. 



CHONDBOPOMA (CHONDBOPS) BIFOBME NEYI, new subspecies 



Plate 33, Figure 10 



I collected this race in abundance in many places on Little Inagua 

 Island. It is an exquisite shell with almost sublamellar axial riblets, 

 which form slight scallops at the intersection with the spiral threads. It 

 resembles most nearly Chondropoma (Chondrops) biforme salarium, 

 but the sculpture is much heavier in every way. 



The type (U.S.N.M. No. 536678) has 4.5 whorls remaining and 

 measures : Length, 10.2 mm. ; greater diameter, 5.0 mm. ; lesser diame- 

 ter 4.3 mm. It was collected along the bay south of North Point. 



U.S.N.M. No. 390S00 contains 207 topotypes from the same source. 



U.S.N.M. No. 390347 contains 63 specimens collected by Bartsch 

 between the west end and South Point, Little Inagua. 



U.S.N.M. No. 392362 contains 5 specimens collected by Bartsch be- 

 tween the hill and the west shore at the south end of Little Inagua. 



U.S.N.M. No. 392185 contains 19 specimens collected by Bartsch on 

 the shore of the bay south of North Point, Little Inagua. 



U.S.N.M. No. 390276 contains 9 specimens collected by Bartsch on 

 the west side of Little Inagua north of the point.
