ribs will at once distinguish it. Like that it has the interrupted band of 

 brown spots at the summit. It differs from the other subspecies of Chon- 

 dropoma (Articulipoma) russelli by its large size and by the exceedingly 

 broadly expanded outer peristome. 



The type (U.S.N.M. No. 472026) is a complete specimen, having 6 

 whorls and measuring: Length, 13.3 mm.; greater diameter, 9.7 mm. ; 

 lesser diameter, 7.8 mm. 



U.S.N.M. No. 402570 contains 9 topotypes from the same source. 



CHONDBOPOMA (ABTICULIPOMA) RUSSEL,!,! TESBORI, new subspecies 



Plate 8, Figure 4 



This race was collected by C. R. Orcutt at his fourth station above 

 Haiti, is much smaller than typical Chondropoma (Articulipoma) russelli 

 russelli, is less conspicuously marked but has the peristome much darker 

 and less flaringly expanded, and has the same close ribbing that char- 

 acterizes russelli. It differs from both russelli and caibai in having the 

 nuclear whorls pale. 



The type (U.S.N.M. No. 472027) has 5.7 whorls remaining and 

 measures : Length, 10.7 mm. ; greater diameter, 6.7 mm. ; lesser diameter, 

 5.8 mm. 



U.S.N.M. No. 472028 contains 10 topotypes from the same source. 



U.S.N.M. No. 402541 contains 3 specimens collected by Mr. Orcutt 

 south of Fonds Verettes on the trail to Bodarie, on the north slope. 



CHONDROPOMA (ARTICUL.IPOMA) BUSSEI.1.I CAIBAI, new eabspecles 



Plate 8, Figure 5 



This race was collected by C. R. Orcutt at his fourth station above 

 Bodarie. It is a small race, being a little more conic in outline of spire 

 than the others and having the nuclear whorls dark, the peristome pale 

 brown, and the whorls more strongly marked with brown, which here 

 assume a vermiculated axial pattern. 



Its small size will differentiate it from Chondropoma (Articulipoma) 

 russelli russelli, and its small size, dark tip, and stronger color mark- 

 ings will distinguish it from Chondropoma (Articulipoma) russelli tes- 

 bori. 



The type (U.S.N.M. No. 472029) is a perfect specimen of almost 6 

 whorls and measures : Length, 9.2 mm. ; greater diameter, 6 mm. ; lesser 

 diameter, 5.3 mm. 



U.S.N.M. No. 402576 contains 9 topotypes from the same source. 



CHONDROPOMA (ARTICULIPOMA) VVOODRINGI, new species 



Shell ovate, varying from unicolor flesh-colored to interruptedly 

 spirally banded to almost vermiculated. The interrupted elements of 

 the spiral bands are arranged in axial series. There is usually an inter- 

 rupted band of brown at or near the summit that even in the unicolor 

 specimens is obsoletely indicated. The nuclear turns begin with a dark
