FARCIMEN (FARCIMEN) UNGULA SEMIVESTITUM, new subspecies 



Plate 1, Figures 25-27 



This race is openly umbilicated. It is much Larger than the other 

 member of that group described here, namely ^ F. (F.) ungula hol- 

 guinense. The specimens retaining their periostracum show this to be 

 wood brown with an olivaceous tinge, streaked with darker axial lines. 

 When denuded, the last whorl is brilliantly reddish orange. The hair- 

 like axial threads in this race are stronger and the base of the last 

 turn is more attenuated than those of F. (F.) ungula holguinense. 



The type, U.S.N.M. No. 535884, from Brazo del Pino, Woodfred, 

 Mayari, Oriente Province, was collected by I. Kivas. It has 6.5 whorls 

 remaining, having lost the nuclear tip, and measures: Height, 33.0 

 mm. ; greater diameter, 13.8 mm. 



FARCIMEN (FARCIMEN) UNGULA HOLGUINENSE, new subspecies 



Plate 1, Figures 13-15 



The type of this subspecies was collected by Garcia Feria at the 

 Finca de Garcet, Holguin, Oriente Province. We also have speci- 

 mens collected by Quesada between Cacocum and San German, and 

 others obtained by Dr. Aguayo at Baguano, east of Holguin, Oriente 

 Province. 



This race shares with F. {F.) ungula semwestitum the open umbil- 

 icus. It differs from it in having a much stronger carina limiting the 

 umbilicus and when denuded in not being brilliant orange on the last 

 turn, and in having the axial hairlike riblets finer. 



The type, U.S.N.M. No. 535877, has 6.3 whorls remaining and mea- 

 sures : Height, 26.5 mm. ; greater diameter, 13.4 mm. 



FARCIMEN (FARCIMEN) UNGULA PERCONVEXUM, new subspecies 



Plate 1, Figures 10-12 



This is a small race, the type of which was collected by Gundlach at 

 Yarayabo, Oriente Province. We also have specimens from Central 

 Palma, Corralillo, northwest of Santiago, from between Baire and 

 Jiguani, also between Baire and Los Negros, and from San Luis, north 

 of Santiago. Likewise from Manaca, La Plata. While widely dis- 

 tributed, it is fairly constant in form, although the coloration varies 

 materially from flesh colored to roseolate. It is nearest related to F. 

 (F.) ungula mayariense, from which its much smaller size will readily 

 differentiate it. 



The type, U.S.N.M. No. 535881, has 5.4 whorls remaining and mea- 

 sures : Height, 24 mm. ; greater diameter, 12.5 mm.
