This species resembles some forms of C. (Corasia) regince, but the 

 spire is raised, the apex blackish, and the last whorl deeply deflexed 

 in front. It is thinner than the other species of Chlorcea. Semper 

 did not find the species on the island Burias, whence it was reported 

 by Cuming. 



The principal color varieties represented in the suite before me are 

 figured on my plate. 



C. CCERULEA Mollendorff. Unfigured. 



Imperforate, depressed, thin, delicately curved striate, decussated 

 by extremely close spiral lines; pellucid, greenish-blue; spire de-

 before the aperture, greenish, at thecolumellanodiferous. Aperture 

 oblique, rounded-trapezoidal ; peristome yellow, sublabiate, expanded

 July-Aug., 1888, p. 97. 



This species recalls C. regince, but it is smaller, the last whorl not 

 so much widened ; the color is a beautiful sky-blue, tinged with 

 bluish-green, the apex brown ; the lip is distinctly but slightly 

 thickened, and of a beautiful yellow as far as the columella; there 

 is a purple-brown spot at the insertion of the columella, and a dis- 

 tinct tooth at its base ; finally, there is a nodule-like thickening on 

 the last whorl at the base of the columella. (v. Moll.)
