These minute shells are plentiful in all parts of the group. 

 For further information in regard to this species see my paper on the Rurutu 

 land shells, published in the Proceedings of the Academy. 



GENUS ASSIMINEA, Leach. 



The animal of A. nitida, which is nearly colorless, has a small oval foot, rather 

 broad head, prominent, transversely wrinkled muzzle, which is dilated and bilobed 

 in front. The conspicuous black eyes are nearly terminal on short, stout, conical 

 tentacles. Locomotion is effected by the aid of the very mobile muzzle. 



The position of the eyes proves the correctness of Mr. Pease's views in regard 

 to the separation of this and many other species from Omjphalotropis and Hydro- 

 cena, and uniting them to Assiminea.

 Eydrocena similis, Baird, Cruise of the Curacoa. 



This small, obscure species is generally distributed throughout Southern Poly- 

 nesia, and ranges from near the sea-shore to about two thousand feet above sea- 

 level. They are found beneath decaying leaves, under stones and dead wood, 

 associated with minute Helices and other small species of land shells. 



I found Mr. Pease's type examples of lucida in beach sand at Anaa, Paumotu 

 Islands. They were worn and discolored by salt water. Living shells, which I 

 subsequently obtained in the same locality, were undistinguishable from his nitida. 

 Adolescent specimens have the body-whorl slightly angulate near the suture.
