OHONDBOPOMA (CHONDBOPOMICM) VEBMICITLATUM NUBILUM, new subspecies 



Plate 3, Figure 8 



This race comes from Barahona. The entire shell is brown except for 

 the buff interior of the aperture and the slightly paler peristome. Through 

 this brown color the fine vermiculations characteristic of the species are 

 shown. 



The type (U.S.N.M. No. 354959) has 4.3 whorls remaining and 

 measures: Length, 17.4 mm.; greater diameter, 9 mm.; lesser diameter, 



7.8 mm.

This is the largest of the four subspecies. The ground color is buff 

 with axial streaks of a paler shade, which give to the shell a somewhat 

 watered silk effect. It most nearly resembles Chondropoma (Chondro- 

 pomiimi) vermiculatum domingense in the color scheme and form, but 

 from this it can readily be distinguished by its much larger size and the 

 pale brown interior of the aperture. 



The type (U.S.N.M. No. 354951), bearing the label "Haiti," has 4 

 whorls remaining and measures: Length, i9 mm.; greater diameter, 



9.9 mm. ; lesser diameter, 8.8 mm. 



U.S.N.M. No. 354953 contains a topot3-pe from the same source. 



OHONDBOPOMA (CHONDBOPOMUJM) VEBMICUI-ATUM VEBMICULATUM, 



new subspecies 



Plate 3, Figure 1 



This race was collected by W. L. Abbott at Trujin near the south- 

 eastern end of the Barahona Peninsula. It is the most slender, elongate- 

 conic race known and has coarser ribs than Chondropoma (Chondro- 

 poniitim) vermiculatum sallci, while the ground color is pale flesh- 

 colored. 



The type (U.S.N.M. No. 354961) has 5.5 whorls remaining and meas- 

 ures: Length, 17 mm.; greater diameter, 9.1 mm.; lesser diameter, 

 7.9 mm. 



U.S.N.M. No. 354962 contains 16 topotypes from the same source. 



U.S.N.M. No. 315 187 contains 2 specimens from the Evezard Col- 

 lection, without specific locality. 



CHONDBOPOMA (CHONDBOPOMIUM) VEBMICULATUM DOMINGENSE, 



new subspecies 



Plate 3, Figure 3 



This subspecies was collected by Salle in "Santo Domingo" without 

 further subspecific locality. In ribbing, shape, and vermiculated mark- 

 ings, as well as in general color pattern, it closely resembles Chondropoma
