During eleven days in the habitat of peninsularis, I saw 

 between fifty and sixty pronghorns, most often singly, but 

 sometimes in groups of two or three. Only once we observed 

 no fewer than eight in one band, two or more of which were 

 bucks; and on another occasion Mr. Rockwell killed a doe 

 that was in company with four other animals. All that we 

 encountered, with one exception, were hopelessly wild — as 

 wary and frightened, indeed, as even such shy ungulates could 

 well be. Moreover, they seemed to absent themselves for 

 days together from large tracts of country through which 

 we had hunted but once or twice. Under such circumstances, 

 our opportunity for coming into close contact with them was 

 very limited. Yet it seems worth while to record such scanty 

 observations as I was able to make, together with brief 

 data gleaned from the experience of Captain Funcke, who, 

 in 1912, collected the type specimen of the peninsular sub- 

 species. 



A fact of particular interest with regard to the Lower 

 Californian pronghorn is that the season of the birth of its 

 young seems to be three or four months earlier than the normal 

 period for antelopes along the Mexican border of the United 

 States. During our hunting in Pattie Basin, April 1-12, 1915, 

 we frequently observed the tracks of does and fawns together. 

 On April 4, our Mexican horse wrangler shot a fawn w^hich 

 he found sleeping among the creosote bushes. Three days 

 later Captain Funcke collected two others of approximately 

 the same size as the first. 



The three fawns were very nearly half -grown. It was 

 evident that they had all been weaned, for their stomachs 

 •were filled with finely-chopped, bright green, fleshy leaves, 

 the whole mass being in a thick fluid state. I examined this 

 pabulum carefully, and found only fragments of succulent 

 leaves, with no trace of grass. 



The first fawn was a male; the second two, which may 

 have been twin sisters, were females. All three were just 

 under a meter long, from nose to base of tail. The skull of 

 the largest fawn was 185 mm. in extreme length, and 92 mm. 

 in breadth across the orbits. The horn knobs of each animal
