Gundlach says of the animal: "Found on the cHffs of the coast of 

 Cuba at the Forts of Morro, Aguadores and Sardinero (about San- 

 tiago). The animal is whitish, almost colorless, with whitish dots, 

 particularly on the head and the base of the tentacles. The tip of 

 the snout and the tentacles ochre red, the tip of the tentacles brown; 

 the body of the animal appears greenish with dark spots through the 

 shell. The animal suspends itself from a mucous thread." 



ANNULARIA (CHONDROPOMATUS) MIMETICA, new species 



Plate 57, Figures 1-3 



Shell subglobular, flesh colored, with an orange tinge and stronger 

 orange shade on the peristome. Nuclear whorls 2, strongly rounded, 

 microscopically granulose. Postnuclear whorls inflated, strongly 

 rounded, marked by retractively curved axial ribs, between which 

 finer axial threads are present. On the fu-st two-thirds of the turn 

 the finer threads are not apparent. The first whorl has 53 ribs, 

 while the last has 67. These ribs terminate at the summit in slender, 

 white tubercles. Of the finer threads from 1 to 4 may be present 

 between the stronger. Suture conspicuously channeled. Periphery 

 strongly rounded. Base inflated, strongly rounded, and marked by 

 the continuation of the axial sculpture. Umbilicus narrow, marked 

 by the contmuation of the axial ribs and 8 feeble sphal tlu'eads. The 

 one, however, limiting the outer termination of the umbilicus is much 

 stronger than the rest, and it renders the axial riblets here nodulose. 

 Aperture broadly pearshaped; peristome double, the inner and outer 

 coextensive and moderately broadly reflected, separated only on the 

 posterior half of the inner lip by an impressed line, and at the posterior 

 angle, where the inner forms a shelf, while the outer is projected into 

 the conspicuous auricle. Operculum as described for the subgenus. 



This species was collected in the region of Maisi, Oriente Province, 

 by Dr. Rodriguez. 



The type, U.S.N.M. No. 425626, comes from Farrali6n de San Lucas. 

 It has 4.8 whorls and measures: Length, 10.2 mm.; greater diameter, 

 9.6 mm.; lesser diameter, 7.8 mm.
