In Prof. Whitney's Preliminary Report on the Survey, Proc. Cal. Ac. p. 27, 

 3f;iy 4th, 1S63, he states ai)proximately as the result of Dr. Cooper's mala- 

 culojrical labours, up to the close of 1SG2 : — 



No. of species in the collection SHij 



Of which pre new to California, and Ijelieved to be undescribed .... 123 

 Other supposed Califoruian species not yet collected 65 



In a Survey conducted with such cure, even negative evidence is of some 

 importance, though not conclusive. Dr. Cooper has not been able to obtain 

 the following species : — 



jyi'/ieina Evnnsii. 



Strujilla carntiria. [Mr. Xuttall's specimens were probably Atlantic] 



Venus dispar. 



Trapezium Calif nrnkimi. '[^ = Dvperryi,= Gtiiniacvm.'] 



Lmina bella. [IVrhaps =pictinata, Cpr. ; but the type seems lost.] 



Mitfliola nitens. [Probably an error in the Cumingrian label.l 



MytiluJi (//oineratu,i,^^ = e(htlis,\a.r.^' [Perhaps an accidental var. from being 



crowded on a floatiny: stick.] 

 Sarbatia pernoides. [Very probably an error in Dr. Gould's label.] 

 Area muliicostata. " Must have been broug-ht to S. Diego." 

 J*ecten purpuratus. [Ascribed to the fauna from abundant valves marked 

 • " Cal."' in the U. S. E. E. collections, but certainly from S. America. Dr. 



Cooper has unfortunately not been able to discover any of the species 



de.scribed by Hds.] 

 Hadius variabilis. " Doubtless exotic." 

 Polinices perspiciui. " Probably Mexican." 

 Hanella triquetra. " Probably Mexican." [Guaymas.] 



105. Having now presented to the student an analysis of all that is yet 

 known of the results of public surveys, it remains that we tabulate what has 

 been accomplished by private enterprise. Mr. J. Xantus, a Hungarian gen- 

 tleman in the employ of the United States Coast Survey under the able 

 direction of Professor Bache, was stationed for eighteen months, ending July 

 1861, at Cape St. Lucas, the southern point of the peninsula of California. 

 It is a source of great benefit to natural science that the Secretary of the 

 Smithsonian Institution is also one of the acting members of the Coast Sun-ey 

 Board ; and that a harmony of operations has always existed between the 

 directors of these two scientific agencies in Washington. The publications 

 of the Coast Survey have earned for themselves a reputation not surpassed by 

 those of the oldest and wealthiest maritime nations. For obtaining data on 

 geographical distribution, Cape St. Lucas was a peculiarly valuable station, 

 being situated near the supposed meeting-point of the two faunas (v. B.A.
