Henderson and Bartsch collected this subspecies at various places 

 in the Cuzco Mountain complex. For example, El Mulo; the upper 

 reaches of the Kio Hondo ; Pena Blanca (El Huro) ; Lomas de Cuzco ; 

 and Salto de Manantiales. The typical subspecies is remarkably 

 smooth, with scarcely any indication of riblets at the summit, in 

 which respect it differs from F. {F.) gundlachi gundlachiellmn, 

 which has slight ribbing on the posterior half of the turns. 



The specimen figured, U.S.N.M. No. 535920, comes from Loma del 

 Cuzco (El Mulo). It has 7.0 whorls and measures: Height, 24.3 

 mm. ; greater diameter, 11.0 mm. 



FARCIMEN (FARCIMEN) GUNDLACHI GUNDLACHIELLUM, new subspecies 



Pl.\te G, Figxtees 1-3 



We have this small race from the mountains north of Candelaria, 

 such as El Taburete, Cayajabos, and Mogote Soton. Its smaller size 

 will readily distinguish it from the other two subspecies. 



The type, U.S.N.M. No. 535924, coming from El Taburete, Caya- 

 jabos, has 5.1 whorls remaining and measures: Height, 19.6 mm.; 

 greater diameter, 10.8 mm. 



Bartsch describes the animal of this subspecies, which he collected 

 at Soton on a hillside west of Taburete, June 11, 1928, as follows: 

 Animal flesh colored with a pinkish suffusion. The tentacles in some 

 specimens are a trifle pinker than the general tone of the body; in 

 others they are coral-red. Eyes black, situated at the outer base of 

 the tentacles. 



FARCIMEN (FARCIMEN) GUNDLACHI ANAFENSE, new subspecies 



Plate 6, Figures 25-27 



This subspecies appears to be restricted to the Sierra de Anafe. 

 We have a lot from Guanajay, Pinar del Kio Province, however, 

 which agrees in every way with it. It resembles most nearly the 

 typical race but is easily distinguished from that by having the axial 

 ribs of the early whorls much finer and more closely spaced. The 

 last whorl is also smoother. 



The type, U.S.N.M. No. 535923, comes from Loma de Anafe. It 

 has 7.0 whorls and measures: Height, 22.3 mm.; greater diameter, 

 11.0 mm.
