C. CASTANEA, Sowb. PI. 42, llg. 15. 



Shell with a shallow channel around the suture, defined by an

 contracted ; chestnut-brown, spotted with white, aperture tinged 

 with orange within. . Length, '85 inch. 



G(flnj)agos Is.; W. Coast of Central America. 



I have considerable doubt whether this is not a variety only 

 of the [)receding species ; it is considerably smaller, more 

 contracted, with more defined slioulder, and colored interior. 



C. FASCJATA, Sowb. PI. 42, figs. 16-18. 



Shell large and thick, oval, slightly shouldered ; brown, spotted 

 with white, the spots sometimes merging into irregular zigzag- 

 longitudinal markings, occasionally obscurely white-banded at 

 the suture and periphery ; teeth of columella and outer lip 

 sometimes tinted witli red. Length, 1-25 inches. 



Java. 

 This s})ecies is not so gibbous as tliose which precede it, and 

 has heavier teeth ; the sjjire is also more convexly elevated. (J. 

 Javacensis, Gaskoin (fig. 18), is probably a faded specimen of 

 fasciafa.
