breaks up into a number of subspecies in this range, descriptions of 

 which follow : 



KEY TO THE SUBSPECIES OF ANNULARIA (ANNULARITA) MAJUSCULA 



Outer peristome greatly thickened. 



Auricle at the posterior angle of the aperture conspicuous. 



Parietal wall of aperture detached from preceding whorl narcisi 



Parietal wall of aperture not detached from the preceding 



whorl cumbrensis 



Auricle at the posterior angle of the aperture not conspicuous. 



Outer peristome of inner lip broad majuscula 



Outer peristome of inner lip not broad. 



Outer lip very greatly thickened crassilabris 



Outer lip not very greatly thickened macta 



Outer peristome not greatly thickened. 



Shell large, length of decollated shell more than 31 mm excelsa 



Shell small, length of decollated shell less than 25 mm catalinensis 



ANNULARIA (ANNULARITA) MAJUSCULA NARCISI, new subspecies 



Plate 36, Figure 3 



This subspecies comes from the limestone blocks adjacent to 

 Candelaria, Pinar del Kio Province. It is readily distinguished from 

 the others by having a decided am'icle at the posterior angle and by 

 the parietal wall usually being free, leaving a depression between it 

 and the preceding turn. The peristome of the outer Up is also im- 

 mensely thickened and it extends back for some distance. By the 

 presence of the auricle it suggests A. (A), majuscula cumbrensis. 



The type, U.S.N.M. No. 356227, was collected near the Escuela de 

 Frias, Candelaria. It is an almost complete specimen having 6.0 

 whorls remaining and measuring: Length, 26.0 mm. ; greater diameter, 

 14.6 mm.; lesser diameter, 12.5 mm. 



ANNULARIA (ANNULARITA) MAJUSCULA CUMBRENSIS, new subspecies 



Plate 36, Figure 7 



This race comes from La Cumbre, north of San Diego de los Banos, 

 Pinar del Rio Province. In shape, color pattern, and thickened 

 outer peristome it resembles typical A. (A.) majuscula majuscula. 

 Its small size and rather conspicuous auricle at the posterior angle of 

 the aperture will distinguish it from that race. 



The type, U.S.N.M. No. 356206, has 3.5 whorls remaining and 

 measures: Length, 27.0 mm.; greater diameter, 18.7 mm.; lesser 

 diameter, 14.6 mm.
