ANNOTATED LIST OF THE AMPHIBIANS AND REPTILES 



Bufo punctatus Baird and Girard 

 Spotted Toad 



Forty-three larvae and recently metamorphosed young of a species 

 of toad (no. 5539) are at hand from North Mountain Spring. I have 

 available no comparable young of punctatus and so cannot be quite 

 certain of the above identification of these young specimens. They are 

 about half the length of Bufo halophilus of corresponding stage of de- 

 velopment ; they are broad-headed and dotted on the back with many 

 small tubercles (red, in life) surrounded with indistinct black circles. 

 The underparts are white and gray in alcohol (bronze-colored beneath, 

 in life). The lower labial teeth in the tadpoles are in two long rows 

 and one short one. The first of these (anterior), in the specimens 

 examined, contained 126 teeth, the second 120, and the third 31 teeth. 

 The comb-like upper lip is made up of from 55 to 65 solidly united 

 teeth, and the lower lip of from 78 to 95 teeth (in three specimens 

 examined). Total lengths, in millimeters, of nearly grown tadpoles: 

 25.4, 24.5, 23.0, 25.0, 25.0. Total lengths of recently metamorphosed 

 young: 10.3, 9.7, 10.2, 10.5, 9.4. 



The tadpoles were found on May 28 in a water-hole at the south end 

 of the Turtle Mountains, five miles from any other spring and thirty 

 miles from the nearest permanent stream. A search revealed some 

 young toads huddled together in the crevices of planks about the pool, 

 and some in wet sand nearby. The toads were active and apparently 

 well fed, having an abundance of small flies to prey upon about the 

 foul water. The sluggish tadpoles, swimming slowly to the surface 

 of the murky, red pool were easily taken in the hand. 



The sporadic occurrence of this amphibian in the driest of North 

 American deserts is noteworthy. 



Testudo agassizii (Cooper) 

 Desert Tortoise 



Four tortoises were collected on July 20, 1909, at Goffs. None was 

 seen at the south end of the Turtle Mountains, though their dens and 

 broken skeletons were found there. 



A large living specimen was obtained in 1908 at Mecca, Riverside 

 County, California. It was said to have been taken in the Cottonwood
