CUBAN SUBFAMILY CHONDROPOMINAE TORRE AND BARTSCH 359 



CHONDROPOMA (CHONDROPOMA) APPENDICULATUM SUBAPPENDICULATUM, 



new subspecies 



Plath 35, Figure 8 



This subspecies was collected by Allen about Gibara, without 

 definite locality. It is smaller and darker colored than the typical 

 race and has stronger sculpture. 



The type, U.S.N.M. no. 468979, has 5.5 whorls remaining and 

 measures : Length, 14.8 mm ; greater diameter, 7.8 mm ; lesser diam- 

 eter, 6.7 mm.

 de la Isla de Cuba, pp. 33-34, pi. 4, fig. 1. 



Truncated shell elongate-ovate. Early whorls decollated in all our 

 specimens. Those remaining flesh-color, with interrupted spiral 

 bands of pale brown. The dots composing these bands are arranged 

 in both axial and spiral series. The whorls are inflated, narrowly 

 shouldered, the shoulder marked by slender, rather regularly dis- 

 posed denticles. The rest of the whorls are marked by retractively 

 slanting axial threads, which are a little stronger on the early turns 

 than on the rest. The spiral sculpture consists of rather distantly 

 spaced, conspicuous, slender cords, of which 8 are present on the 

 first of the remaining turns, 11 on the second and 12 on the last be- 

 tween the summit and suture. The junctions of the axial threads 

 and spiral cords form slender nodules, which are materially reduced 

 on the last turn, which bears a mere indication of them. Suture nar- 

 rowly channeled. Periphery of the last whorl inflated, well rounded. 

 Base short, inflated, well rounded, and marked by spiral cords of the 

 same strength and spacing as those on the posterior half of the whorl. 

 Within the umbilicus, however, they become less conspicuous. Aper- 

 ture large, very oblique, broadly oval, rather strongly auriculated at 

 the posterior angle ; peristome double, the outer and inner coextensive 

 on the outer lip, and but slightly differentiated at the posterior angle, 

 on the parietal wall and on the inner lip. 



The specimen described and figured, U.S.N.M. no. 493287, was col- 

 lected by Dr. de la Torre at Gibara, Oriente Province. It has a 

 little more than 3 whorls remaining and measures : Length, 12.0 mm ; 

 greater diameter, 6.9 mm ; lesser diameter, 6.0 mm.
