GRAND CANYON NOTES. 



On a first and brief visit to the Grand Canyon 

 of Arizona, June 6-10, 1916, en route to California, 

 as might be expected, little time was available for 

 herpetological observations. The few notes that were 

 taken seem worth recording, chiefly because they come 

 from a region of such extraordinary interest. 



Two days were spent in conventional trips along 

 the rim of the Canyon, the third day on a walk down 

 the Bright Angel Trail to the Colorado River, and 

 the fourth and last day in Camp near the Indian 

 Garden on the inner plateau of the Canyon. 



The dry season being well advanced, no batrach- 

 ians, but many lizards of the genera Sceloporus and 

 Holbrookia, were seen on top of the Canyon. Lizards 

 in the Canyon averaged larger in size, and in addi- 

 tion to the genera mentioned included Crotaphytus, 

 Gerrhonotus and Cnemidophorus. A specimen of 

 Sceloporus clarhii captured in the Indian Garden is 

 still living in the New York Zoological Park. 



Two Batrachians — Hyla arenicolor and Bufo 

 punctatus — were common in the Canyon. 



Hyla arenicolor was observed along the small 

 stream which runs through the Indian Garden, enters 

 a narrow inaccessible gorge and reappears at the 

 foot of the Bright Angel trail near the Colorado 

 River. Dense thickets of willow, sedges, etc., border 

 the stream, except at trail crossings, where clear, shal- 

 low pools have formed. In and about these pools the
