CUBAN SUBFAMILY CHONDROPOMINAE — TORRE AND BARTSCH 281 

 KEY TO THE SUBSPECIES OF CHONDROTHYRETES DELECTABILIS 



Axial dark zone behind peristome present delectabilis 



Axial darlv zone behind peristome absent. 



Interrupted spiral bands between summit and suture 5 palmaris 



Interrupted spiral bands between summit and suture 4. 



Rays on outer lip fairly strong bellamaria 



Rays on outer lip feeble or obsolete amabilis 



CHONDROTHYRETES DELECTABILIS DELECTABILIS, new subspecies 



Plate 17, Figure 1 



This race comes from Caiguanabo, the eastern part of the Sierra 

 Guacamayas. 



The type, U.S.N.M. no. 468798, has 3.3 whorls remaining, and meas- 

 ures: Length, 18.4; greater diameter, 11.5 mm; lesser diameter, 

 8.2 mm. 



It is easily distinguished from the other three races by the fact 

 that here the dark axial band behind the peristome is missing. It is 

 also more strongly spirally banded, particularly so on the back of 

 the expanded peristome. 



CHONDROTHYRETES DELECTABILIS PALMARIS, new subspecies 



Plate 17, Figure 5 



This race comes from the Mogote de Vegas Nuevas, 3 kilometers 

 from La Palma. 



The type, U.S.N.M. no. 468803, is a complete specimen having al- 

 most 7.0 whorls and measures: Length, 18.2 mm; greater diameter, 

 11.2 mm; lesser diameter, 7.9 mm. 



It also has the dark axial zone behind the peristome but has five 

 slender spiral interrupted bands between the summit and suture. 



CHONDROTHYRETES DELECTABILIS BELLAMARIA, new subspecies 



Plate 17, Figure 2 



This race comes from the Mogote Bella Maria on the north side of 

 Sierra San Andres near La Palma. 



The type, U.S.N.M. no. 468801, has 5.5 whorls remaining and meas- 

 ures: Length, 20.5 mm; greater diameter, 12.0 mm; lesser diameter, 

 8.9 mm. 



Here we have a strong dark axial band behind the peristome, four 

 interrupted slender spiral bands of brown, and rather strong rays 

 on the outside of the outer lip.
