CUBAN ANNULiARiroAE — TORRE AND BARTSCH 287 



umbilical wall. The last whorl is solute for about one-tenth of a turn 

 behind the expanded peristome, which touches the preceding turn on 

 the parietal wall, but which does not fuse with it. Aperture almost 

 circular; peristome double, the inner fairly strongly exserted and very 

 slightly reflected; the outer broadly expanded on the inner and parietal 

 wall, narrow on the outer lip, forming a conspicuous auricle at the 

 posterior angle, which is reflected backward. The outer peristome 

 is marked by a series of concentric lamellae. Operculum typically 

 annularid. Siphon immediately behind the peristome of the pos- 

 terior angle of the aperture, reflected backward into the suture. 



The specimen described and figured, U.S.N.M. No. 425685, is one 

 received from Dr. Welch, who collected it at Loma Merino, Florencia, 

 Camagiiey Province, the type locality. It has 5.3 whorls remaining 

 and measures: Length, 16.0 mm.; greater diameter, 7.5 mm.; lesser 

 diameter, 6.7 mm. 



We have specimens from various localities along the coast mountain 

 range known as Sierra de Jatibonico, and the Sierra de Meneses. 



This species most nearly resembles A. (A.) terneroensis, which, how- 

 ever, has the whorls shorter and more inflated, the shell more ovoid, 

 and the color markings much stronger. The outer lip of the outer 

 peristome is also broader. 



ANNULARIA (ANNULARODES) OBSOLETA, new species 



Plate 29, Figure 6 



Shell rather large, elongate-ovate, var5ang in color from straw 

 color to pale brown. Unicolor, or marked with interrupted spiral 

 bands of browm. Nuclear whorls almost 2, inflated, strongly rounded, 

 microscopically granulose, forming a blunt apex. Postnuclear 

 whorls increasing rather rapidly in size, inflated, strongly rounded, 

 and marked by retractivelj'^ curved axial ribs, of which 56 occur on 

 the first and 127 are on the last whorl. These ribs are less wide than 

 the spaces that separate them, and they are either singly or by a 

 fusion of two expanded into hollow cusps at the summit. Suture 

 well constricted. Periphery mflated, strongly roimded. Base in- 

 flated, strongly rounded, openly umbiHcated, and marked by the con- 

 tinuation of the axial ribs, which extend into the umbilicus, the 

 umbilical wall bearing many rather closely spaced, low, rounded 

 spiral threads, which render the axial riblets sHghtly nodulose. The 

 partial covering of the umbilicus by the reflected peristome makes 

 it impossible to determine their actual number. Aperture circular; 

 peristome double, the inner exserted and slightly reflected; the outer 

 broadly expanded, mostly so on the inner lip, which quite obscures 

 the umbilicus when viewed from the front, and on the parietal wall,
