THE CAPE REGION OF BAJA CALIFORNIA. 
BY WALTER E. BRYANT. 
I. SAN JOSE DEL CABO AND VICINITY. 
The following discursive account of the so called ‘‘ Cape Region”’ 
of Baja California, Mexico, is based mainly upon the writer’s ex- 
perience while collecting in 1890, for the California Academy of 
Sciences. This was my fifth visit to that interesting strip of Mexi- 
ean territory and the third of the expeditions sent out annually by 
the Academy. All of the previous trips had been either to islands 
_of*the western coast or the mainland of the peninsula from the vi- 
cinity of Magdalena Bay (bet. lat. 23° and 24° N.) and northward. 
The object of the expedition of 1890 was the collecting of the ter-

to supplement the collections obtained farther north in previous 
years. Still there were other objects of interest not to be neglected, 
and inso far as it was possible to do so in connection with the other 
branches, collections were to be made of the insects, particularly 
-coleoptera, and of the land and fresh water shells and fresh water 
fishes which were met with. I was accompanied by the genial and 
accomplished botanist, Mr. T. S. Brandegee, to whose explorations 
and publications of the flora of the peninsula, are due the greater 
part of the existing knowledge concerning Lower Californian bo- 
tany; as well as having at all times the assistance of one or more 
of the native population. 
The cape region treated of in this paper may be described as 
that terminal portion of the peninsula southward from the northern 
base of the mountains between La Paz on the Gulf shore and the 
town of Todos Santos on the Pacific Coast. The term cape region 
is derived from Cabo San Lucas, the extreme southernmost part of 
the peninsula, but when used faunally includes a much greater ex-
