NATIVE MAMMALS OF PASADENALAND. 



In 1886 Prof. C. F. Holder, LL. D., was engaged by the Board of 

 Trade to furnish literary and scientific articles to eastern and northern news- 

 papers, on such matters in and about Pasadena as he could utilize, and thus 

 bring this city extensively before the reading public abroad.* The Union 

 of October 30 published a list of his writings under this engagement, which 

 numbered a total at that time of eighty-four articles furnished by him to the 

 press of Boston, New York, Philadelphia, San Francisco, and various New 

 England cities. He also made contributions to the local press of Pasadena 

 and Los Angeles up to 1889. Among these writings are his descriptions 

 of the native animals here ; and from these I make the following extracts :

The Jack Rabbit, which is properly a hare, and is known to science 

 as Lepiis Californicus. The hares never burrow, forming nests upon the 

 surface in the grass and there rearing their young, while the cotton tail 

 forms a deep burrow, after the fashion of all rabbits. The hare of New 

 Mexico, Arizona and Texas, also called the "Jack Rabbit," is a diflferent 

 species, <yL. Callotis,') though to the casual observer there is little difference. 



Kangaroo Rat. — One evening at Las Casitas, near Pasadena, I saw 

 in the dim light a curious object hopping along, which I found to be one of 

 the queer jumping mice, so called, an animal known scientifically as Dipo-
