It is distinguished from the other forms with closed umbilicus and 

 nonobese shape by having the whorls rounded. 



FARCIMEN (FARCIMEN) UNGULA MAYARIENSE, new subspecies 



Plate 1, Figures 1&-21 



This subspecies was collected by J. B. Henderson at the Farallones 

 de Nipe, Piedra Gorda, Canapu, near Cayo del Key, all places near 

 Mayari. The type comes from Farallones de Nipe. 



The race is most nearly related to F. (F.) ungula ungula (Poey), 

 from which its less protracted aperture and stronger axial sculpture 

 will readily differentiate it. 



The type, U.S.N.M. No. 535883, has 7.2 whorls and measures: 

 Height, 28.0 mm. ; greater diameter, 14.0 mm. 



FAKCIMEN (FARCIMEN) UNGULA MAYENSE, new subspecies 

 Plate 1, Figures 16-18 



This race was collected by Dr. Ramsden about Alto Songo, La Maya, 

 Finca Isabelita, and Finca Santa Teresa, Oriente Province. It is a 

 rose-colored race with closed umbilicus and a strong carina bordering 

 it. The whorls are marked by rather strong slightly retractively 

 curved axial riblets, which become weakened on the last turn. 



The type, U.S.N.M. No. 535885, from La Maya, has 7.5 whorls re- 

 maining and measures : Height, 27.9 mm. ; greater diameter, 13.5 mm. 



The brilliant rose color will differentiate this easily from the other 

 members with closed umbilicus. 



FARCIMEN (FARCIMEN) UNGULA GUANTANAMENSE, new subspecies 

 Plate 1, Figures 22-24 



We have this subspecies from a number of stations ranging about 

 Guantanamo. The individual stations are Vinculo, where the type 

 was obtained, Saltadero, Sierra des Canasta, and Yateras, Oriente 

 Province. 



This is an orange-colored race with closed umbilicus. It resembles 

 most nearly F. (F.) ungula tnayetise^ from which its less strong axial 

 sculpture and paler coloration will differentiate it. 



The type, U.S.N.M. No. 535886, has 7.4 whorls and measures: 

 Height, 18.6 mm. ; greater diameter, 13.8 mm. 



FARCIMEN (FARCIMEN) CAMAGUEYANUM, new species 



Shell of medium size, elongate-ovate, varying in color from uni- 

 formly wax yellow to bicolor, that is, the early whorls may be pale 

 and the last darker, frequently dark chestnut-brown. Nuclear whorls 

 about 1.5, well rounded, smooth. Postnuclear whorls strongly
