 tnit! S. iKiinmoiulii. Such are specimens collected l>y Dr. Ifaydeii in the. 

 valley of the (Jreat Colorado, in eastern I'tah, and others (d)tained l»y 

 myself at Santc Fe, N. Mex. In some of the former the interorbilal 

 wi«ltli enters the ieii^-th of the tibia three and a half times. 



The Sjua nt<njiutJh is known as yet fi'om yonnj;- spccimens-oniy, which 

 hav(^ but recently passed their metamorphosis. The principal peculi- 

 arity which characterizes them is tie minute si/e of the ostia phar.\n- 

 ^i'ca of the Eustachian tubes. I suspect this to be a character of imum- 

 turity, as I find a similar state of affairs in some of the younj,' speci- 

 mens of Scapldopiis coiicltii in the collection.

I took a specimen of this si)ecies within the limits of Salt liake City, 

 and subseipiently obtaiiu'd tiiree or f(Uir sju'cimeus from Pyramid Lake, 

 Nevada. The sides and much of thiMbusal re<;ionarecovered with rather 

 larnc lidu'rcles closely jdaccd. The frontoparietal bones, though ossi- 

 fied, ate not ronjiliencd, as in the species of Scaphiopus. It is nearest 

 the S. coH('/(// (from near San Antonio, Tex), in that si)ecies the vo 

 luerine teeth are entiiely posterior to the internal nares; in this (uie 

 they are between the fiosterior bordi'rs of the same. The lips arc^ not 

 cross barred, as in the A', couch ii ; and the superior rejiion has two 

 pale lines on each side. In *S'. coiicliil these lines are replaced by a 

 coarse, uuirblinf;'. As compared with the Sj)(<( IkdiuiioikIH, this froj; 

 differs in its lar';er size, lighter colors, and the presence of the superior 

 pair of light lines.

It represents the .S. Iinmiiiontli in more uortherii regions, and the com- 

 plete cranial ossification and larger size mark it as a more fully devel 

 o2)ed form. 



I found it associated with Biifo coUonbicitsis in a pond near tlu^ shore 

 of Pyramid Lake. Like other allied s[»ecies, it was very noisy, almost 

 obscuring' the voice of the less vociferous liido.
