Alter a study of tlie numerous specinuMis in tlie <'olIc(;tiou of tlic Na- 

 tional Musenui, I am convinced that this spe('ies is entitled to lull lecoi;' 

 nil ion. The dilVciences from the /.'. hiitlijiiinsus, its nearest ally, are 

 innncroiis. These inclinle the form of the cranial crests, the shape of the 

 paidloid <,'lands, and the develoi>ment of the metatarsal spurs. It is also 

 easily recojunizabh^ by the coloiation. 



What I l>ehev»' to be a lar;;e younjjf sjieciinen of this species served 

 as th(> type of my />'///<« diptrrnus. AlthoUKh i\n inch ami a half lon<r, 

 this individual had not developed a trace of the cranial crests. The 

 dorsal spots also are smaller than in any specimen I have seen. I ob- 

 taiiieil two other specimens of about th(^ size of the type and three 

 smaller ones near the .Indith K'iver. Montana. 



This is chielly a species of the i)laius; but it extends into the li0(d<y 

 Mountains also.
