fessor Cope as above, led to an erroneous assignment of Fort Whipple as 

 the locality. The specimen was taken in the desert in the vicinity of La 

 Paz on the Colorado River, and I am confident it does not occur in the 

 higher mountainous parts of the Territory. 



The "Gila Monster", as this large and repulsive looking reptile is 

 called, appears to he not uncommon in the hot, southern parts of the Ter- 

 ritory. A poisonous property is attributed to its saliva by the Mexicans, 

 with whom the belief is also prevalent that it has the power of spirting its 

 supposed venom. The females of the same ignorant people have a super- 

 stitious belief in the influence that this and some other Saurians may exer- 

 cise over certain periodical functions of their sex. I am informed by Dr. 

 H. C. Yarrow that in some localities they attribute to Amblystoma a miracu- 

 lous power of causing conception — a form of superstition doubtless found 

 convenient at times, especially if shared by their male relatives.
