1902. Megalomastoma (Farcimen) hituberculatum minor Kobelt, Das Tierreich, 

 Cyclophoridae, p. 265. 



This subspecies was collected by H. N. Lowe at Puriales, Santa Rosa, 

 Trinidad, Santa Clara Province. It agrees with the typical race, F. 

 (F.) hituberculatum lituberculatum (Sowerby), in having the whorls 

 strongly rounded but differs from it in being more ovate and in having 

 the last whorl plum colored. 



The specimen figured, U.S.N.M. No. 535902, has 5.0 whorls remain- 

 ing and measures : Height, 28.5 mm. ; greater diameter, 15.3 mm. 



FARCIMEN (FARCIMEN) BITUBERCULATUM GIGANTEUM, new subspecies 



Pl.4,te 3, Figures 1-3 



We have this subspecies from Sopimpa, a railroad station between 

 Fomento and Trinidad, and Loma del Caballete, Sierra de Gavilanes 

 of the Trinidad region, Santa Clara Province. It differs from the 

 other races of F. (F.) bituberculatum in having the axial ribs of the 

 later turns irregularly developed; in size it resembles F. (F.) hituber- 

 Gulatum gutierrezi and F. (F.) hitubercyidatum crassum, from both of 

 which the irregularity of its ribs will distinguish it. 



The type, U.S.N.M. No. 535904, which comes from Sopimpa, has 5.0 

 whorls remaining, and measures : Height, 33.7 mm. ; greater diameter, 

 17.8 mm. 



FARCIMEN (FARCIMEN) BITUBERCULATUM GUTIERREZI, new subspecies 



Plate 3, Figures 4-6 



We have this race from a number of stations ranging around Banao, 

 south of Sancti Spiritus and southeast of Trinidad, Santa Clara 

 Province ; for example, Finca Angelina, La Quinta, El Cacahual, and 

 Guayacanes ; also from Loma de Jarao, Blanquizal, near Guayos. 



This is a large pale race, as large as if not larger than F. (F.) 

 hituherculatum giganteum, from which it is easily differentiated by 

 being unicolor. The two races are also zoogeographically distinct. 



The type, U.S.N.M. No. 535906, comes from Finca Angelina and 

 has 5.4 whorls remaining. It measures : Height, 36.8 mm. ; greater 

 diameter, 18.6 imn. 



FARCIMEN (FARCIMEN) BITUBERCULATUM CRASSUM, new subspecies 



Plate 3, Figures 13-15 



This subspecies comes from the southern mountain complex of 

 Santa Clara Province. We have it from Finca Pita j ones, the Cara- 

 cusey Valley, Trinidad; Loma de Gabino Galvez; Loma Esperanza
