Thi.s toad iias vory much the appearamu* of one of the Scaphiopida', 

 and it i.s not unlikely that its habits are, like tlieirs, subterranean. 



TIk^ specimen fif^ured as Bii/o .spcciosns by IJaird in the Uejjortof the 

 Alexiean boundary Survey (No. 1'<)11), frouj JVs(|iiiera, in Ntu^vo Leon 

 is not tyi»i(*al of the />. vDmpuctili.s. it has feeble traces of the crania 

 crests of the Hiifo nuinatus, and some lar;;o brown dorsal spots not found 

 in other specimens. Three spectimens from Kansas (.V.iDi) possess similar 

 iiidimeMtal crests, and a fifth specimen of the sanu^ character was sent 

 me from the Wichita River, in central northern Texas, by Jacob IJoll. 

 These specimens Ibreshadow the characrters of the liii/o viKjnatns; while 

 not aitproachin;,' it in the devcloinneiit of the cianial crests. In the 

 Dallas specimen the dorsal spots are of medium size, while in those 

 iVom Kansas they are vi'ry small or waMtin.n'. I suspect that the cranial 

 cliaracteis bi-loiii;- to a race whiiih ranines farther north than the true 

 liiifii coin ii((cl ills, which may at some time be ic^arded as a subspecies, 

 under the name of Jl, voiiiitdctili.s njuriosus. The true />'. comiKictilis 

 occurs ill southwestern Texas, and ranjjes as far south in 3iexico as 

 the Isilimiis (»f Teliuantei»cc.
