We were at first under tbe impression that we had a new species 

 before us. It appeared to be nearly related to C. phyllostoma, Heude, 

 yet we could not believe it to be the same species, as it differed from 

 the figure given in the " Mollusques terrestres," which showed a much 

 more slender shell with only three plicfe palatales. The text contains 

 no Latin description, but Pore Heude states that the species 

 might possibly prove to be identical with his C. indnrata. Now 

 C. indnrata, H., is C. gigas, Molldif., as we have already shown, and 

 since our species is certainly not C. gigas we were about to describe it 

 under the name of C. Bocki, when we came across the description of 

 C. phyllostoma published in the Journal de Conchyliologie, 1888, 

 the existence of which we could not have known, since no reference is 

 made to it in the "Mollusques terrestres." After a study of this 

 description we have come to the conclusion that the species before us 

 is C. phgllosfoma, Heude ; since our figure had, however, been drawn 

 and the description written, we do not suppress them, since they will 

 in some points supplement those given by the Reverend Pere. 



C. gigas, MoUdff., is no doubt a near ally of C. phyllostoma, but 

 in the latter the whorls decrease gradually in width towards the apex, 

 while in C. gigas they become narrower suddenly, so that C. gigas is 

 club-shaped. The texture, too, is different. C. phyllostoma is finely 

 striated, while C. gigas is " rugoso-striatus " and its surface therefore 

 rougher. The lamella subcolumellaris of C. gigas is not visible within 

 the aperture, while in C. phyllostoma it is distinctly produced to the 

 margin. The lip of C. gigas is considerably thicker, and finally 

 C. gigas has five plicoe palatales, all of about equal length, whilst of 

 the 6-7 plica) palatales of C. phyllostoma the upper one is considerably 

 longer than the others. 



C. Belavayana, Heude {I.e. p. 118, t. xxxi. fig. 5), differs in not 

 being decollated ; the lamella superior is neither so well developed, nor 

 is it marginal ; the lamella inferior is further from the lamella 

 superior, and finally there are nine plica3 palatales instead of 6-7.

Heude gives the dimensions as alt. 25, diam. 5 mm., which has 

 made it impossible to recognise the species, the more so as the last 

 volume of the " Mollusques terrestres," containing tlie figure, had not
