Notes on certain Terrestrial Molhtsca. 



During the last two years M. Crosse has repeatedly called 

 my attention to the importance of examining the animal of 

 some species of the group to which C. Maitgeri belongs. Lately, 

 I obtained from my friend I^atli. Wilson, the distinguished 

 Botanist of Jamaica, several specimens of C. BlandianaVW'.^ 

 placed by Yon Martens in the subgenus Lia of Macroceramus. 

 Although the animals were dead, I secured the lingual ribbons. 

 I found no jaw, and seeing the character of the teeth, believe 

 that none exists. 



From the accompanying figure (by Morse), it will be seen 



that in form and arrangement the 



teeth are decidedly of CyUndreUa 



type. The median tooth is long and 



narrow, terminating in a single cusp. 



The laterals are bicuspid ; posterior 



margin of the plates fringed ; anterior 



cusp fringed, ])08terior cusp bluntly 



notched. The formula 55-1-55 x 145. 



This seems to establish the fact that 



Zm, and I believe Anoma also, must be separated from 



Macroceramus^ and that, in accordance with the views of 



Pfeifferand 11. and A. Adams, they belong to CyUndreUa.
