CUBAN SUBFAMILY CHONDROPOMINAE TORRE AND BARTSCH 225 



6.5 ^yhol•ls. It measures: Length, 24.1 mm; greater diameter, 18.4 

 mm ; lesser diameter, 13.3 mm. 



Two specimens of this subspecies have been found by Dr. de hi 

 Torre that do not have a breathing pore. One of these is U.S.N.M. 

 no. 469125; the other is in Dr. de la Torre's collection. 



CHONDROPOMETES (CHONDROTHYROMA) MAGNUM SIGNAE. new subspecies 

 Plate 12, Figuke 14 



Shell of medium size, thin, the early whorls reddish, the last one 

 flesh-color, marked by rounded dots, which are arranged in both axial 

 and spiral series. The peristome is white with a yellowish flush. The 

 last whorl is almost adnate, being free only immediately behind the 

 peristome, which is adnate to the preceding turn. 



The type, U.S.N.M. no. 385144, and a series of specimens were col- 

 lected by Bartsch while working under a grant from the Walter Eath- 

 bone Bacon Traveling Scholarship in 1928, on the three mogotes east 

 of Cabezas. It has 3.6 wliorls remaining and measures: Length, 

 17.0 mm ; greater diameter, 16.2 mm ; lesser diameter, 12.5 nmi. 



CHONDROPOMETES (CHONDROTHYROMA) SACCHARINUM, new species 



Shell large, varying in color from pale to dark reddish brown, with 

 obsolete darker s})iral bands. Axial ribs rather low and moderately 

 closely spaced. Peristome white or pale brown. Operculum white. 



This species, which is now known only from I^in de Azucar and the 

 Cueva del Martillo, in the Sierra Martillo range that connects the 

 Sierra Chichones with the Sierra Celadas and del Infierno, resembles G. 

 {€.) magnum in size and color of operculum, while in strength of 

 axial ribs and their spacing and in a lack of spiral lirations it ap- 

 proaches G. {G.) eainiimn, differing markedly from this, however, in 

 the color of the operculum. 



Distribution of the subspecies of G. (G.) sacchannum is shown in 

 figure 78.
