1 . Mblania plumbea Brot. 



Journ. de Conch. 1864, p. 19 ; Kuster's Conch. Cab. F. p. 310. 



Two shells, from between Base and Cano Camps. 



Neither specimen is quite so elongated in the spire as the specimen figured by Brot. 

 One of them lacks the costae on the body-whorl, variability in the occurrence of which 

 appears to be characteristic of the species. 



2. Diplommatina sp. 



One shell from vegetable debris, Cano Camp. 



This is a small markedly triangular form, having six whorls closely set with diagonal 

 finely decussated ribs, and exhibiting other characters that differentiate it from the 

 other known species of the genus. The author does not feel justified, however, in 

 making a new species upon the shell of a single specimen.

3. Calycia crtstallina (Eeeve). 



Conch. Icon. 1848, pi. 32 {Bulimns crystallinus). 

 One shell from Camp III. (2500 ft.K 



According to Pilsbry, this form, originally considered to be a Bulimoid, is now to be 

 placed among the Zonitidae on good anatomical grounds.
