6 Notes on certain Terrestrial AJoUusks. 



Helix cornu-militare L. 



PfeifFer refers this fine species, on the authority of Dr. Jay, 

 to the Sandwich Islands. Many individuals were collected in 

 1853 in that part of the Island of Haiti, which constitutes 

 the Dominican Eepublic, by Salle, who favored me with a 

 specimen. 



Helix Formosa Fer. 



This species has been generally attributed to Guadaloupe. 

 I have received a considerable number, one with the aniip.al 

 alive, from the Rev. A. Hamilton, who collected them in 

 Antigua. 



Helix orbiculata Fer. 



Pfeiffer gives Guayana and Cayenne as habitat; numeruus 

 specimens were prCvSented to me by the late Mr. J. M'Muna\-, 

 collected by him in St. Lucia. 



Helix Pallasiana Pfr. 



Bermuda is stated by Pfeiifer, erroneously I believe, to be 

 the habitat of this species; he refers to the shell as in 

 Mr. Cuming's possession.- In the cabinet of Mr. Lounsbury, 

 I lately detected a shell which agrees pretty closely with 

 Pfeilfer's desci-iption, entirely, so with Reeve's figure, and 

 identical with two specimens unnamed in the collection of 

 Mr. J. H. Redfield, received from Dr. Newcomb, as from the 

 Bonin Islands. Mr. Shuttleworth informed me in 1854, that 

 he had an individual of this species from Mr. Cuming, who 

 gave as habitat, the Corean Archipelago. I found no trace 

 of it in Bermuda, nor did the late Professor C. B. Adams. 



Helix penicillata Gould. 



Dr. Gould admits, in correspondence with M. Poey and 

 myself, that his shell is a variety of II. Cuhensis Pfr. 1 do 

 not know H. penicillata Pfr., Mon. iii. No. 1287.
