galls and the Cynipids bred from them; and from E. R. Leach, 122 moths 

 from Michigan Bluff, California. Other donations to the department collec- 

 tion were received from Virgil Owen and Dr. F. C. Clark of Los Angeles; 

 Dr. F. W. Goding of Guayaquil, Ecuador; M. C. Van Duzee of Buffalo; B. 

 G. Thompson of Sacramento, including topotypes of the very rare Destnocerus 

 dimorphus; from Jos. Mailliard and E. O. Essig, including paratypes of 

 some interesting species, and others from Dr. F. C. Clark, Dr. F. E. Blaisdell 

 and Mrs. H. E. Ricksecker, which are still unmounted and will have to be 

 recorded another year. Not only are these gifts unusual in number but they 

 are of exceptional value. 



The Academy collection of insects has now reached such a size that the help 

 of a preparator is almost a necessity if any progress is to be made in the 

 classification of the material. During 1923 less will be required for the pur- 

 chase of new cases and it is hoped that this will supply in part the funds 

 needed for the hire of an assistant. Our collection of insects is much too valu- 

 able to be stored in packing boxes. They should be determined and arranged 

 in systematic order and so made available to students who may need to consult 

 western forms, but this taxonomic work cannot be done while the curator is 

 doing the work of a preparator. Edward P. Van Duzee, Curator.

The beginning of the year 1922 saw the completion of the habitat group of 

 the Imperial Grizzly Bear (Ursus horribilis imperator) , which was donated 

 to the Academy by Mr. Ogden Mills, of New York. The specimens for this 

 group were secured in the Yellowstone National Park, Wyoming, by Dr. 

 Saxton Pope and Mr. Arthur Young, principally by means of bows and ar- 

 rows, and presented to the Academy by Dr. Pope. The group was designed 

 and prepared by Mr. C. J. Albrecht, of the University of Washington, and 

 the background was painted by Prof. C. C. Judson, of the University of 

 California. 



In June last a handsome present was made to the Academy by Mr. George 

 C. Beckley, of San Francisco, California, consisting of thirteen finely mounted 

 heads of the following animals: One moose, two caribou, three mountain 

 sheep, one mule deer, one mountain goat, two antelope, and three elk. 



Material for another sheep group, consisting of five specimens, was secured 

 in Southern California by Mr. Edwin H. Ober, and presented by him to the 

 Academy at the end of the year. 



In the spring of 1922 Mr. Frank Tose was employed for small group work, 

 which has been resumed. There is no more room at present for large habitat 

 groups of birds or animals, but between those large groups now installed there 

 yet remain spaces for several small panel groups, three of which have already 

 been put in place by Mr. Tose. One of these is a group of the Bushy-tailed 

 Wood Rat (Neotoma, cinerea occidentalis) , one of the Western Robin (Pla- 

 nesticus migratorius propinquus), and one of the Western Meadowlark (Stur- 

 nella neglecta). 



No large habitat groups can be installed until either a complete new wing 

 is constructed, with halls set apart for this purpose, or until a sadly needed
