ally, and the names of other friends — Mr. J. W. Towne, of San Fran- 

 <;isco, Samnel Pillsbury, Henry W. Henshaw, and Ileury Hemphill 

 occur. The latter, as well as Mr. L. Beldiug, of California, and Dr. 

 Edward Palmer, have added many species and examples of interest 

 and importance to the national collection. 



All of the species credited to San Juanico, on the outer coast of the 

 peninsula, and Loreto were collected by Dr. Gabb. All of those 

 referred to Altata were ijresented by Mr. A. J. Gove, of San Fran- 

 cisco, who received them directly from the parties who collected them 

 at the locality stated. With a few exceptions, all of the species herein 

 listed are contained in the National Museum, having formed a part of 

 the Stearns Collection. This list is, however, not quite complete. There 

 are several species, notably of Chitons, not yet determined, that should 

 be added, and doubtless a few small species may ultimately be found in 

 the general collection that were collected by Mr. Fisher and have been 

 overlooked, for the department of mollusks in the National Museum has 

 reached such vast proportions, the registered numbers already exceed- 

 ing 126,000 trays, that omissions are likely to occur in a paper of this 

 character, through want of time to make a critical examination and 

 revision. 



The latitu<le and longitude of the ^•arious localities referred to are 

 given below, commencing at the Coronado Islands, the most northerly 

 on the ocean side, off the ])eninsulaof Lower California, aiul ])roceeding 

 southerly to Cape St. Lucas; thence northerly along the western shore 

 of the Gulf of California, including the islands; thence along the eastern 

 shore of the gulf, following the same and the mainland along the Mexi- 

 can coast to the last or most southerly locality, Acapulco, in latitude 

 10° 55'. 



In my lists of the shells collected at San Juanico and Loreto by Dr. 

 Gabb, heretofore mentioned, I referred to San Juanico as being "on 

 the east side of the peninsula of Lower California in latitude 27"^ north." 

 This was an error occasioned by my following the localities as given 

 in Prof. C. B. Adams' list of the " Shells of Panama ;" and due no 

 doubt to the fact of there being two places, one on eachsideof thepenin- 

 sula of the same name. To prevent mistakes, I have listed the San 

 Juanico of the eastern side as Point San Juanico (see San Juanico 

 Cove). In connection with Boca de los Piedras, frequently referred to, 

 see Estera d'? los Piedras in the list of localities. 



Delays due to various causes have enabled me to add the collections 

 made by the Albatross naturalists, Prof. Leslie A. Lee and his assist- 

 ants, in 1887-'88 at Ballenas and Pichilinque bays, etc., so far as the 

 same have been worked up at this date. 



Several species of land shells inhabiting the Gulf region are included 

 in this paper; for further information, relating to those of Lower Cali- 

 fornia more j)articularly, attention is called to Dr. Cooper's three papers
