HISPANIOLAN AND BAHAMAN ANNULARIIDAE 63 



CHONDROPOSIA (CHONDROPOMA) KYERDAMI £TERDAMI, new subspecies 



Plate 11, Figure 6 



This race was collected by Walter J. Eyerdam on the shore of the 

 Saline near Madame Siadae on the south-central coast of Gonave Island. 

 It is easily distinguished from Chondropoma (Chondropoma) eyerdami 

 parislvae by its much larger size and darker coloration. 



The type (U.S.N.M, No. 471957) has 4 whorls remaining and meas- 

 ures: Length, 17 mm.; greater diameter, 10.6 mm.; lesser diameter, 

 8.9 mm. 



U.S.N.M. No. 380165 contains 18 topotypes from the same source. 



U.S.N.M. No. 381013 contains 10 specimens collected by Eyerdam 

 I mile northeast of Point-a-Raquette, Gonave Island. 



U.S.N.M. No. 380177 contains 5 specimens collected by Eyerdam on 

 the shore of Saline, Gonave Island, 



U.S.N.M. No. 393587 contains 2 specimens collected by Eyerdam at 

 the caves of En Cafe, Gonave Island. 



CHONDROPOMA (CHONDROPOMA) EYERDAMI PARISHAE, new subspecies 



Plate 11, Figure 3 



This race is represented by a single partly broken specimen collected 

 by Mrs. S. W. Parish at the southeastern point of Gonave Island. It 

 can readily be distinguished from Chondropoma (Chondropoma) eyer- 

 dami eyerdami by its smaller size and paler coloration. 



The type (U.S.N.M. No. 499351) has 3.8 whorls remaining and meas- 

 ures: Length, 13.7 mm.; greater diameter, 7.9 mm.; lesser diameter, 

 7 mm. 



CHONDROPOMA (CHONDROPOMA) TORTUGAErNSE, new species 



Plate 12, Figure 4 



Shell small, elongate-ovate, flesh-colored, with interrupted bands of 

 brown. These bands are arranged in axial series of dots, which are very 

 distantly spaced. Peristome white. Nuclear whorls a little more than 2, 

 strongly rounded, smooth, forming a slender apex. The postnuclear 

 whorls are marked by rather distantly spaced, slender, retractively 

 curved, almost sublamellar axial riblets and feeble spiral threads, which 

 are also distantly spaced; that is, they about equal the axial ribs in 

 spacing. The intersection of these two elements forms sharp nodules, 

 whose long axis coincides with the axial sculpture. Summit of the 

 whorls appressed. Suture fairly strongly constricted. Periphery well 

 rounded. The base is moderately long, well rounded, and marked by the 

 same sculptural elements that characterize the spire, but a little less 

 strongly expressed. Within the umbilicus spiral threads are present, 

 which are stronger than those on the spire, while the axial riblets become 

 closely approximated and enfeebled. The last whorl is solute for a frac- 

 tion of a turn. The aperture is almost circular. Peristome double; the
