Note, — In the late "Catalogue of Shells in the Museum 

 of the Academy," etc., including the geographical dis- 

 tribution of species known from Sitka to Cape St. Lucas, 

 many are given as from "West Coast, lat. 26°," and 

 southward. These were collected by the late Dr. Gabb 

 at San Juanico on the west coast of the peninsula, but 

 the locality having been confused with one on the east 

 side, in the gulf, at about the same latitude, it was uncer- 

 tain which coast they were from. In his late paper Dr. 

 Stearns credits them all to the west coast. (See "Zoe" 

 for April, 1892.)
