Thus it was the zoological work of Dr. Cooper in con- 

 nection with this survey that has so enlarged our real 

 knowledge of the zoology of this section. Thus, from 

 December 1860 until April 1862, and a considerable por- 

 tion of 1863 he was collecting in the Colorado Valley near 

 Fort Mojave. This included the vicinity of San Diego, 

 San Pedro, Santa Barbara and the islands of the coast. 

 In 1864 he explored a portion of the coast from Bolinas 

 Bay to Santa Cruz, and during a portion of this time 

 (1862) was assisted by Dr. Edward Palmer. During this 

 period he did a large amount of gratuitous work, in the 

 way of elaborating the material in various branches of 

 the zoology of the Pacific Coast. In 1865 he prepared 

 his series of reports on the higher classes of animals. We 

 hope that this preliminary sketch will call attention to 

 Dr. Cooper's ornithological work, and while it is not in- 

 tended to be critical, we have attempted to do him 

 justice as an original observer and as an author. In a 

 subsequent issue of the BULLETIN we will give a detailed 

 catalogue of his ornithological publications expressly pre- 

 pared for students who wish to examine them.
