sliellt^. and ijeilnqjs obtained by comnierce from that spot, are 

 known to be inhabitants of the Pacific Islands and the East 

 Indies, that a list of them wonld be entirely useless for our 

 present object.*' 



The closing lines of Dr. Carpenter hardly Justify the previous 

 remark, '"an exploration in competent hands," etc.; and a re- 

 curi'ence to the species cited shows, that even so eminent an 

 authority as Prof. Forbes was, to use a common expression, "at 

 sea," in the matter of locality ;* while the box-labels were more 

 nearly, if not cpiite right. Mr. Binneyf gives the habitat of 

 Kellcttii US "San Diego; Catalina Island, San Nicolas Island, 

 California ;" and CooperJ refers it to "Catalina Island, San 

 Diego and south." The latter author does not refer to H. 

 Pandorce, as it is not an inhabitant of the Calif ornian and 

 Vancouver zoological province, being south of the southern limit 

 of his catalogue, Avhicli covers the region " between latitudes 

 33° and 49° north." 



Binney, in the volume quoted, properly credits If. Pandorce 

 to "Margarita Bay, Lower California." Forbes's habitat of this 

 species is only seventeen hundred miles too far north, — and of 

 .Kellettii, eleven liiuidred. 



Another distinguished autlior|| has placed the Lower Califor- 

 nian Helix levis on the Columbia river, — about fifteeri hundred 

 miles too near the north pole. 



Tryon§ proper!}' credits it to Southern California,^ and adds 

 in a note that our mutual friend, Dr. ISTewcomb, sent him speci- 



* Forbes's " San Juan del Fuaco," perhaps should have been San Juanico, 

 a small port in Lower California on the outer coast, lat. 26° N., and within 

 the territory inhabited by Pandorce, areokda, etc. For the sake of brevity, 

 it is often called " San Juan."
