 name I have furnished it to correspondents, but always with 

 some " mental reservation."

In Mr. Cuming's collection this shell has the name of 

 A. elevata Newc., and the name gracilis Pfr. is attached to a 

 variety of A. striatula Gould. From a careful examination of 

 the descriptions, and the figure given by Dr. Pfeiffer, I do not 

 doubt their identity, and have thus placed elevata as a synonym. 



In the Proceedings of the Zoological Society for November, 

 1855, Dr. Pfeiffer described in my name several species which 

 I had forwarded to Mr. Cuming. In July preceding four of 

 these species were described by me in the Proceedings of the 

 Natural History Society, Boston, on pages 218, 219, and 220, 

 and in the month of September I gave seven additional ones 

 in the Annals of the Lyceum. (Vol. vi. p. 142-147.) The 

 names of the species that Dr. Pfeiffer so kindly gave me, be- 

 sides those referred to, are, A. Mauiensis, A.fulva, A. ovifor- 

 mis, A.pulla, A. elevata, A. ohtusa, and A. apicata.

This species should be doubtfully received. The original in 

 Mus. Cuming is but a variety of A. vulpina Fer., denuded of 

 epidermis.
