The race from the island of Batan averages a little smaller in all 

 dimensions than Cochlostyla dubiosa capulensis. It is also less 

 brilliantly colored with the incised spiral lines a little more strongly 

 developed. 



The specimen figured is an average specimen, collected by Quadras 

 at Santo Domingo de Vasco. It has 4.5 whorls and measures — 

 height, 28.9 mm.; greater diameter, 33.2 mm.; lesser diameter, 

 25.1 mm. 



COCHLOSTYLA DUBIOSA CAPULENSIS, new subspecies 



Plate 1, Figures 5-8 



This race from the island of Capul is the most elegant of the three. 

 The lines of growth and incised spirals are fewer than in the other 

 two races, and the shell has a smoother aspect. Here too the brown 

 band at the summit is narrow, while those above and below the pe- 

 riphery are broad. The umbilical area is not darker than the rest of 

 the base. The ground color of the last turn is bright horn colored 

 where the diaphanous bands have been worn away. The early turns 

 are white, the middle ones flesh colored with a pale zone of brown at 

 the summit and the suture. 



The type. Cat. No. 315731, U.S.N.M., an average specimen, has 

 4.8 whorls and measures — height, 32.0 mm.; greater diameter, 

 33.1 mm. ; lesser diameter, 26.9 mm. 



COCHLOSTYLA SUBMIRABILIS MolIendorfT 



This species as we have mentioned under CocMostyla duhia 

 Pfeiffer has been in part confused with that species and some of 

 the races have been confounded with Cochlostyla mirahilis Ferus- 

 sac. From Cochostyla dubia it is distinguished by the extremely 

 reduced, practically absent, incised spiral lines, while the presence 

 of hydrophanous spiral bands distinguish it from Cochlostyla Tmra- 

 hilis Ferussac.
