MONOGRAPH OF THE GENUS STROPIIIA. 
he considers that he did not fully appreciate the extreme variation to 
which the species was subject, therefore he did not at first describe a

synonym. 
Dr. Gundlach states that the shell occurs on bushes and under 
leaves near Gibara, Cuba, and that the living animal is white or gray 
with the head and neck blackish with a blackish roughness, in contrast 
with which the white colors of the feelers [eye stalks?] show more 
plainly. The feelers have the tips gray. 
The following is a transcription of Dr. Pfeiffer’s description with a 
translation.
