CROCIDOPOMA (CYCLOCUBANA) GUNDLACHI IGNOTUM, new subspecies 



Plate 8, Figures 7-9 



In the Evezard collection of the National Museum there are two 

 specimens of a subspecies for which we have no specific locality. They 

 are distinguished from the rest of the material at hand and agree per- 

 fectly with each other. "VVe are, therefore, reluctantly bestowing a sub- 

 specific name upon them. 



The type, U.S.N.M. No. 535775, has 4.3 whorls and shows at the aper- 

 ture 10 spiral cords between the summit and the suture, 7 on the base 

 and 7 on the umbilical wall. This measures: Height, 4.8 mm; greater 

 diameter, 9.0 mm ; lesser diameter, 7.0 mm. 



The other specimen, U.S.N.M. No. 316425, has 4.2 whorls and the 

 same number of spiral cords as the type, and measures : Height, 7.4 

 mm. ; greater diameter, 8.2 mm. ; lesser diameter, 6.8 mm. 



The extremely small number of spiral cords differentiates it from the 

 other two races. 



CROCIDOPOMA (CYCLOCUBANA) GUNDLACHI GUNDLACHI, new subspecies 



Plate 8, Figures 1-3 



This subspecies was collected by Gundlach at Monte Toro. 



The type, U.S.N.M. No. 535773, has 4 whorls and at the aperture 

 shows the following number of cords: Between the summit and the 

 periphery 10, on the base 10, on the umbilicus 16. It yields the follow- 

 ing measurements : Height, 6.3 mm. ; greater diameter, 10.9 mm. ; lesser 

 diameter, 8.4 mm. 



CROCIDOPOMA (CYCLOCUBANA) GUNDLACHI WRIGHTI. new subspecies 



Plate 8, Figures 4-6 



In the National Museum we have four specimens collected by Charles 

 Wright at Potosi, Oriente Province. Potosi, while not on recent maps, 

 from information at hand we know is situated somewhere north of 

 Monte Libano and Felicidad. These specimens are differentiated from 

 the other two members by being a little more closely coiled. 



The type, U.S.N.M. No. 535774, has 4.1 whorls and measures : Height, 

 5.1 mm. ; greater diameter, 8.9 mm. ; lesser diameter, 6.9 mm. It has 12 

 spiral cords between the summit and the suture, 11 on the base, and 8 

 on the umbilical wall, a total of 31 when viewed at the aperture. 



The other two specimens are complete and yield, respectively, the 

 following information: Number of whorls, 4.1 and 3.7; number of 

 spiral cords between the summit and suture, 12 and 12 ; spiral cords on 

 base, 10 and 8; spiral cords on the umbilical wall, 10 and 10. They 

 measure respectively: Height, 5.3 and 5.0 mm.; greater diameter, 8.3 

 and 8.2 mm. ; lesser diameter, 6.5 and 6.2 mm.
