CHONDROPOMA (CHONDROPOMORU8) GNOTE ENNERYENSE, new subspecies 



Plate 2, Figure 7 



This race was collected by E. C. Leonard on the summit of the moun- 

 tains near Ennery, Haiti. It, like Chondropoma (Chondropomorus) gnote 

 tuobi, has exceedingly strongly developed tufts at the summit, even more 

 so than that race, but here the interrupted spiral bands are slender 

 and narrow and more numerous, and the whole color scheme is paler. 



The type (U.S.N.M. No. 471994) has 5.9 whorls remaining and 

 measures : Length, 14 mm. ; greater diameter, 7.3 mm. ; lesser diameter, 

 6.1 mm. 



CHONDROPOMA (CHONDROPOMORUS) GNOTE TUOBI, new sabspecies 



Plate 2, Figure 5 



This race comes from the region of Sans Souci, Haiti. It has previ- 

 ously been confused with Chondropoma (Chondropomorus) petitianum, 

 certain races of which occupy the same region, but from which its 

 smooth surface will at once distinguish it. 



It is differentiated from the other subspecies of this group by its 

 broadly conic outline and by its having the tufting at the summit strongly 

 developed, in which respect it resembles Chondropoma (Chondropo- 

 morus) gnote enneryense, but it is readily distinguished from this by 

 having the brown spots of the interrupted spiral bands very broad and 

 very strongly developed, usually developing into blotches instead of 

 mere lines as in enneryense. 



The type (U.S.N.M. No. 471991) comes from Sans Souci, Haiti. It 

 has 5.5 whorls remaining and measures: Length, 15.3 mm.; greater 

 diameter, 8.7 mm. ; lesser diameter, 6.7 mm. 



U.S.N.M. No. 471942 contains 6 topotypes from the same source. 



U.S.N.M. No. 403811 contains 24 specimens collected by Orcutt on 

 limestone rocks 39.8 miles south of Cap Haitien. 



CHONDROPOMA (CHONDROPOMORUS) GNOTE KRIEGERI, new subspecies 



Plate 2, Figure 8 



This subspecies was collected by H. W. Krieger during his archeo- 

 logical explorations in Hispaniola at the village site of the Irawak 

 Indians at the mouth of the San Juan River, which is on the north 

 side of the Samana Peninsula in the Dominican Republic. 



It is a pale race beautifully regularly spotted by interrupted spiral 

 bands of brown, which are few in number and distantly spaced axially. 

 The spots here all tend far more toward an axial arrangement than in 

 Chondropoma (Chondropomorus) gnote gnote. Here, too, the tufting 

 at the summit is much more pronounced. 



The type (U.S.N.M. No. 471997) has 5.5 whorls remaining and 

 measures: Length, 13.5 mm.; greater diameter, 7 mm.; lesser diameter, 

 5.3 mm. 



U.S.N.M. No. 425527 contains 5 topotypes from the same source.
