Family HELODERMATIDiE. 

 Heloderma suspectum Cope. 



It is curious that the exact range of so conspicuous and so far-famed 

 a species as the Gila monster is still greatly in doubt. Southern Ari- 

 zona seems to be the center of its distribution, and from there we have 

 a number of well authenticated records based upon specimens, but as 

 soon as we get outside of that Territory the records become uncertain, 

 and the localities given are vague. Thus we have l Mohave Eiver ' given 

 by Baird upon the authority of Kennerly and Mollhausen (Pac. U. B. 

 Hep., X, Whipple's R., Zool., p. 38) which would introduce the species 

 into the Oalifornian fauna, but no specimen seems to have been brought 

 home, and the record remains dubious. Yarrow (Wheeler's Exp., W. 

 100 Mer., Y, p. 562) states that it is "not uncommon in U£ah, New Mex- 

 ico, and Arizona" and that "several specimens were secured in 1871, 

 1873, and 1874, but with one exception (specimen from Arizona collected 

 in 1873) all were lost in transit to Washington." The New Mexico 

 record refers probably to the observation near San Ildefonso of "a large 

 lizard, presumably Of this species" by one of the packers. Whether 

 specimens were actually secured in Utah, I don't know, nor has any 

 other Utah record come to my certain knowledge. 



It is therefore very interesting to note that Dr. Merriam found the 

 dead carcass of a Heloderma near the Yirgin Eiver, in eastern Nevada, 

 the first authentic record from that state. 



The specimen was in too bad shape to be preserved, but two of the 

 feet were cut off and brought home as evidence (No. 18040). As the 

 fourth finger, without claw, measures 22 mm , it is plain that the speci- 

 men was one of large dimensions. 



[One of the most unexpected discoveries made by the expedition was 

 the finding of a Gila monster by Mr. Bailey and myself in the Yalley
