CUBAN ANNULARIIDAE TORRE AND BARTSCH 285 



Periphery well rounded. Base well rounded, narrowly umbilicated, 

 marked by the continuation of the axial riblets, and within the narrow 

 umbilicus by weak spiral threads. Last whorl solute for a tenth of a 

 turn behind the peristome, which touches the preceding whorl. 

 Aperture broadly ovate; peristome double, the inner slightly exserted; 

 the outer broadly expanded on the mner lip and on the parietal wall, 

 where it is somewhat fluted, narrowest on the outer lip, forming a 

 conspicuous auricle at the posterior angle. Operculum typically 

 anniilarid. Siphon behind the posterior angle of the apertiu-e reflected 

 backward into the suture. 



This species appears restricted to the mountains of southern Santa 

 Clara Province, where we are recognizing two subspecies : 



KEY TO THE SUBSPECIES OF ANNULARIA (ANNULARODES) TERNEROENSIS 



Umbilicus moderately broad indioensis 



Umbilicus narrow terneroensis 



ANNULARIA (ANNULARODES) TERNEROENSIS INDIOENSIS, new subspecies 



Plate 29, Figure 5 



This subspecies was collected by Bermudez at El Indio, near San 

 Juan de los Yeras, Santa Clara Province. 



It differs from^. (A.) terneroensis terneroensis in being shorter, more 

 ovate, with a broader umbilicus and by having the axial ribs of the 

 last whorl more closely spaced. 



The type, U.S.N.M. No. 535620, has 3.4 whorls remaining and 

 measures: Length, 12.8 mm.; greater diameter, 7.7 mm.; lesser 

 diameter, 6.7 mm. 



ANNULARIA (ANNULARODES) TERNEROENSIS TERNEROENSIS. new subspecies 



Plate 29, Figure 2 



This race was coUected by Mr. Henderson at Loma del Ternero 

 about 7 miles southeast of San Juan de los Yeras, Santa Clara Pro- 

 vince. It differs from A. (A.) terneroensis indioensis in being more 

 elongate, in having the ribs on the last whorl a little more distantly 

 spaced, and in having a narrow umbilicus. 



The type, U.S.N.M. No. 493403, has 4.2 whorls remaining and 

 measures: Length, 15.4 mm.; greater diameter, 8.0 mm.; lesser 

 diameter, 7.2 mm. 



ANNULARIA (ANNULARODES) CANTARILLENSIS. new species 



Plate 29, Figure 4 



Shell elongate-ovate, straw colored, with faint, interrupted spiral 

 bands of brown. Nuclear whorls 1.8, inflated, strongly rounded, 

 microscopically granulose, forming a rather blunt apex. Postnuclear 

 whorls inflated, strongly rounded, marked by slender, retractively
