536 REPORT— 18C3. 



discrimination, abundant carefulness, and unwearied diligence and patience, 

 no one was belter fitted to collect materials for a scientific survey of the coast. 

 But, unfortunately for his (as for the Nuttallian) shells, he did not describe them 

 at the time himself. They were subjected to all the derangements caused by 

 frequent changes of residence, and transmission to various naturalists for 

 identification. As we know what errors creep into the collections of the 

 most learned under such circumstances, it is not surprising that they should 

 now have lost much of their geographical value. After several days spent 

 in a very searching elimination of the west-coast shells from his general col- 

 lection, I was driven to the conclusion that several labels had become mis- 

 placed. This was so clearly the case as to certain N. England and W. Indian 

 species interchanged with Pacific specimens, that it might also affect (e. g.) 

 Sta. Barbara and Panama specimens as compared with each other. The kelp 

 driven up by the great storm may have travelled from remote localities ; which, 

 will account for tropical shells having been found at Sta. Barbara, as W. 

 Indians -occasionally are even on our own shores. It is possible also, as the 

 Californian seas have as yet been but little dredged, that deep-water species 

 live there which as yet are known only in the tropical pi'ovince. Already 

 some Gulf species have been thus obtained at San Diego and Catalina Island 

 by Dr. Cooper, just as Mr. M'Andrew dredged Mediterranean species on the 

 coast of Norway. But facts of such importance should rest on better e\'idence 

 than chance shells picked on a beach, and subjected to dangers of altered 

 labels afterwards. "What was regarded by Dr. Gould as of authority is cata- 

 logued, according to his determinations of species, on pp. 226-231 of the first 

 Report. The following is a list of the species which I found in the collection^ 

 divided simply into the temperate and the tropical faunas. 



Sj^ecies of tlie Temperate Fauna, collected by Col. Jeivett^. 



Pholadidea penita, ovoidea. 



Saxicava pholadis. 



Scbizotheirus Nuttallii. 



Cryptomva Califomica. 



Lyonsia Californica. 



Solen Psicarius, var. rosaceus *t. 



Machfera patiila. 



Solecurtus Californianus, subteres. 



Macoma nasuta, secta. 



Lutricola alta. 



Semele decisa, rubrolineata. 



Donax Califomicus, flexuosas*. 



Standella PCalifornica. 



Trigona crassatelloides. 



Psephis tantilla*. 



Amiantis callosa. 



Chione succiucta, fluctifraga, simillima. 



* This collection belongs to bis daughter, Mrs. Boyce, of Utica, N.Y. The Colonrl's 

 invaluable collection of U. S. Palaeozoic fossils (probably the largest made by any indivi- 

 dual's own hand) may be consulted at the State Museum in Albany, and will probably 

 find its ultimate destination at one of the principal colleges. A large number of tlie 

 fossils described by Prof. Hall were from this collection, though often without acknow- 

 ledgment. Only a small proportion of the types of the celebrated ' Palaeontology ' are 

 to be found in the State Collection, which was subjected to disastrous and very extensive 

 curtailment before Col. J. entered on his present duties as curator. 



* These species and marked varieties were first found by Col. J. 



f Of these forms, either not seen or not distinguished by Dr. Gould, the diagnoses ara 

 written, and will probably be found in one of the scientific periodicals for 1864. 



J Unless otherwise stated in the list, Report, pp. 228-231, it may be presumed that 

 these species were from the neighbourhood of Sta. ijarbara.
