TEE MUSEUM OF VERTEBRATE ZOOLOGY 

 OF THE UNIVERSITY OF CALIFORNIA 

 The Museum of Vertebrate Zoology of the 

 University of California is represented dur- 

 ing the present year by parties carrying on 

 fauuistic exploration in three regions. 



The expedition to the Colorado Valley 

 under the immediate leadership of Joseph 

 Grinnell, director of the museum, returned on 

 May 17, after three months' work along the 

 river from Needles to Yuma. Over 3,000 

 specimens of mammals, birds, and reptiles 

 were obtained, some of the species being new 

 to the known fautia of California. The im- 

 portant fact was brought out that the Colo- 

 rado River serves, at least in this portion of 

 its course, as an effectual barrier for at least 

 ten species of small mammals; that is, in no 

 one of these cases does the range of the species 

 cross the river. For example, three species of 

 pocket-mice (Perognathus) occur abundantly 

 on the Arizona side, and three other and dis- 

 tinct species occupy corresponding assoeia- 

 tional belts on the California side. 



Mr. Walter P. Taylor, assistant in the mu- 

 seum, now has a party in the Warner Moun- 

 tain region of extreme northeastern Cali- 

 fornia. It is already apparent from their 

 work since entering the region May 15, that 

 the Sierran and Great Basin faunas are curi- 

 ously blended in the Warner Mountains. To 

 express it otherwise, there is an uneven inter- 

 mixture of the representative elements of the 

 two regions. 



Miss Annie M. Alexander, founder and pa- 

 tron of the museum, is with three assistants 

 exploring the interior of northern Vancouver 

 Island. Specimens have been obtained there 

 of a distinct form of beaver, and of mountain 

 lion, black bear, and other carnivorous mam- 

 mals, besides large series of the smaller mam- 

 mals and birds. The work on Vancouver Is- 



land began in April and will extend through 

 September. The results are expected to add 

 to the knowledge of the zoogeography of the 

 region. 



All the specimens and field notes obtained 

 on these three expeditions become the prop- 

 erty of the University of California, and on 

 them are to be based special faunal studies.
