CUBAN ANNUIARUDAE TORRE AND BARTSCH 295 



ANNULARIA (ANNULAROPS) SEMICANA ORGANICOLA, new subspecies 



Plate 30, Figure 9 



This subspecies appears to extend through the western Organ 

 Mountains. We have seen it from Pan de Azucar; the old Isabel 

 Maria (of Wright); Santo Tomds; the mogotes Dos Hermanos and 

 those adjacent to these; Cuajanl in the eastern end of the Sierra del 

 Injiemo; El Queque; Sierra de Vinales; Costanera del Abra; Hato 

 Morales, 



The shells of this subspecies are more elongated than those of A. 

 (A.) semicana semicana and a reddish coloration prevails. 



The type, U.S.N.M. No. 356258, comes from Mogotes Dos Hermanos 

 near Vinales. It has 4 whorls remaining which measm-e: Length, 

 14.8 mm.; greater diameter, 11.6 mm.; lesser diameter, 8.6 mm. 



ANNULARIA (ANNULAROPS) SEMICANA NANA, new subspecies 



Plate 30, Figure 2 



This subspecies extends over the mogotes bordering the Pinar del 

 Rio-Luis Lazo road between Sumidero, Cabezas, and Isabel Maria, 

 thence thi'ough some of the mogotes bordering the east side of the 

 Organ Mountains and possibly a few spots in the Sierra del Infierno, 

 and mogotes bordermg the road between Vinales and the Puerta del 

 Anc6n, thence some mogotes in Laguna de Piedras to Hoyo Largo de 

 San Antonio off the Sierra de San Andres. It appears to be a mogote 

 form, not an occupant of the main sierras. 



The small size readily distinguishes it from the other races. 



The type, U.S.N.M. No. 385056, was collected by Bartsch near the 

 stone quarry, on the first mogote on the north side of the road east of 

 Cabezas. It has 3.4 whorls remaining and measures: Length, 10.4 

 mm.; greater diameter, 7.0 mm.; lesser diameter, 5.8 mm. 



ANNULARIA (ANNULAROPS) CORONADOI (Arango) Poey 



Shell small, elongate-ovate, flesh colored or yellowish white. Nu- 

 clear whorls almost 2, well rounded, smooth. Postnuclear whorls 

 inflated, strongly rounded, marked by crowded sublamellar axdal ribs, 

 wliich are rendered wavy by the low, rounded spiral threads. Suture 

 strongly constricted. Periphery inflated, well rounded. Base in- 

 flated, well rounded, marked by the continuation of the axial ribs and 

 by spiral tlireads, the latter a little stronger than those on the spire. 

 Aperture circular; peristome double, the inner moderately exserted; 

 the outer rather broadly expanded, notched on the middle of the inner 

 hp with the part posterior to the notch reflected over the umbilicus, 

 which it plugs, extending as a broad callus upon the parietal wall of 

 the outer peristome; the rest is of about the same width and is
