THE CYCI/OPHOBID hAND MOLLTJSiKS' OF AMEiRIOA 9 



FARCIMEN (FARCIMEN) UNGULA ELEPHANTINUM, new subspecies 



Plate 2, Figures 13-15 



This very obese race was collected by Dr. S. Molina at Loma Santa 

 Fe, Guantanamo, Oriente Province. The only member of the wigula 

 complex resembling this is F. (F.) ungula mirandum (Pilsbry) , from 

 which its conspicuous tumid umbilical keel distinguishes it. It is also 

 more inclined toward lemon-yellow, instead of being rosy in coloration, 

 and the basal lip is more protracted. 



The type, U.S.N.M. No. 535887, has 5.0 whorls remaining and mea- 

 sures : Height, 32.3 mm. ; greater diameter, 17.3 mm.

 Year Book for 1928, p. 17. 



This subspecies was collected by Drs. Pilsbry and d'Alte Welch at 

 Central Miranda, between Mayari and Santiago, Oriente Province. 

 It resembles in obeseness F. (F.) ungula elephantinum but is dis- 

 tinguished by having the shell much more roseolate and the umbilical 

 bounding keel less conspicuous. Also, the lip is not protracted as in 

 that subspecies. 



The specimen described and figured, U.S.N.M. No. 464468, a topo- 

 type, has 6.0 whorls remaining and measures: Height, 33.0 mm.; 

 greater diameter, 15.9 mm.

The typical race we have from Santiago, Vista Alegre, San Juan 

 Hill and the Pedrito Quarry near Santiago, central Oriente, and the 

 mouth of Magdalena Eiver. The type was collected at Santiago and 

 given to Poey by Dr. Gutierrez. 



The subspecies is of medium size, varying in color from pale lemon 

 to very faintly roseolate. It has the peristome decidedly protracted 

 at the junction of the outer and basal lip, giving it a decidedly ungulate 

 appearance. The umbilicus is practically covered by the reflected peri- 

 stome, the last whorl being materially attenuated, and terminates in a 

 fairly conspicuous carina, marking the outer limit of the umbilicus. 



The specimen described and figured, U.S.N.M. No. 104436, is one re- 

 ceived from Poey collected at Santiago. It has 6.5 whorls remaining 

 and measures : Height, 29.0 mm. ; greatest diameter, 13.2 mm.
