measures: Length, 14.3 mm.; greater diameter, 7.4 mm.; lesser diam- 

 eter, 6.8 mm. 



This species agrees in the soluteness and deflection of its last whorl 

 with A. (A.) canoaensis, from which it is easily distinguished by the 

 broad inner lip of the outer peristome. 



ANNULAKIA (ANNULARODES) CANOAENSIS, new species 



Plate 28, Figure 8 



Shell elongate-ovate, varying in color from straw color to pale 

 brown, marked by rather pale, interrupted spiral bands of brown. 

 Nuclear whorls decollated in all our specimens. Postnuclear whorls 

 inflated, well rounded, marked by slightly retractively curved axial 

 ribs, of which 45 occur on the first and 110 on the last whorl. These 

 riblets become expanded into feeble denticles at the summit or 2, 3, or 

 4 may become united to form a low hollow white cusp. Suture well 

 constricted. Periphery of the last whorl weU rounded. Base mod- 

 erately long, well rounded, marked by the continuation of the axial 

 ribs, which extend into the umbilicus, and on the umbilical wall by 13 

 feeble spiral threads, which render their junctions with the axial ribs 

 feebly nodulose. The last whorl is solute for about one-sixth of a 

 turn, decidedly deflected. Aperture subcircular; peristome double, 

 the inner moderately exsertcd and slightly reflected; the outer rather 

 narrow all around, forming a conspicuous auricle at the posterior 

 angle, where it is reflected over and adjoins the siphon. The outer 

 peristome is marked by concentric lamellae. Operculum typically 

 annularid. The siphon is short, backward directed, and free. 



The type, U.S.N.M. No. 535617, was coUected by Dr. de la Torre 

 at Casimbas de la Sierra de Canoa, Santa Clara Province. It has 4.4 

 whorls remaining and measures: Length, 14.0 mm,; greater diameter, 

 7.5 mm.; lesser diameter, 6.5 mm. 



We have seen specimens also from Vereda del Alunado, Sierra de 

 Jatibonico, which is nearby. 



This species, like A. (A.) uncinata, has the last whorl solute and 

 deflected, but is at once differentiated from that by its much narrower 

 outer peristome of the inner lip. 



ANNULARIA (ANNULARODES) TERNEROENSIS, new species 



Shell elongate-conic, flesh colored, with broad interrupted spiral 

 bands of brown, of which 4 occur between summit and suture and 4 

 are present on the base; the spiral bands show plainly in the interior 

 of the aperture. Nuclear whorls 2, smooth, well rounded. Post- 

 nuclear whorls slightly inflated, weU rounded, marked by rather 

 distantly spaced, well-developed, retractively slanting axial riblets, 

 which either singly or by the junction of two adjacent ones develop into 

 slender hollow denticles at the summit. Suture strongly constricted.
