CUBAN SUBFAMILY CHONDROPOMINAE TORRE AND BARTSCH 373 



much stronger than in the other races. The color markings on the 

 peristome also extend more prominently over the outer lip. 



The type, U.S.N.M. no. 493277, was collected by John B. Henderson 

 at Loma de Santa Fe. It has a little more than 5 whorls remaining 

 and measures: Length, 13.9 mm; greater diameter, 6.1mm; lesser 

 diameter, 5.2 mm.

Plate 33, Figure 1 



This is the other small race that has the sculpture stronger than 

 the typical C. {C.) delatreanum delatreanuin and the denticles at the 

 summit stronger and more distantly spaced. The last whorl is also 

 much more solute. 



The type, U.S.N.M. no. 493279, comes from Loma de Bonachea, a 

 limestone hill on the north side of the road leading from Santa Clara 

 to Kemedios, 5 or 6 miles from Santa Clara. It has 4 whorls remain- 

 ing and measures: Length, 11.1 mm; greater diameter, 5.8 mm; lesser 

 diameter, 4.5 mm.

This race occupies the region about Soledad and Trinidad, Santa 

 Clara Province. It is one of the two small races with the sculpture 

 less strongly developed than in the others. It usually has a some- 

 what oily appearance and the denticles average finer than in the 

 other small race, C. (C.) delatreanum bonacheum, from which it 

 also differs by having the last whorl less solute. 



The specimen described and figured, U.S.N.M. no. 493267, comes 

 from near Guanao, 5 miles east of Cienfuegos. It has a little more 

 than 5 whorls remaining and measures: Length, 11.1 mm; greater 

 diameter, 5.4 nmi ; lesser diameter, 4.2 mm. 



CHONDROPOMA (CHONDROPOMORUS) AUBERIANUM (Orbigny) 



Shell elongate-conic, pale brown, marked by narrow elongated 

 brown spots, which form almost continuous spiral bands. Nuclear 

 whorls 2, inflated, forming a truncated apex, the first very finely 

 granulose, the last half of the last with fine indistinct axial threads. 

 Postnuclear whorls well rounded, marked by well-elevated, retrac-
