found III every ilht'ctiou aloii;; tin' bonlerH ami river viillevH of tlic lir.st 

 plateau ro^^ioii of Texas. Mr. (>. W. Mariioiik, who discoverotl it, in- 

 forms me that after rains it is very noisy, niakin;^ the roeUs resound 

 with its cry, whieh is somewhat like a doj^'s bark. It hi(h's in fissures, 

 and is so dilUcult to lind as to be generally ujdvuown to the (rountry 

 j.'ople, who suppose that the voice proceeds from a lizard. Ac»;ording 

 to Mr. Marnock the ejj;gs are hatched in winter, and the tatlpoles pass 

 their existemie in temporary pools of rain-water which collects in holes 

 in the rocks and at a distance from the creeks.

Additional specimens of this species received from Mr. Marnock show 

 that it reaches a laryer size than the above specimens indicate. I give

In the hujie aiul old specimens a mineral deposit takes place in the 

 skill, as in the I'ln/llomcdiisa sclcrodcnua Cope and tSfen'ncjjclo2}s incrafiH 

 siilns (!ope. It is ('specially abundant in the cranial derm, but whieh is 

 not, as in cases where the ossilication appears on the surface of the 

 cranial bones, adheient to the latter. 



The Ilyhxlcs aiiffiisti (Duges IMS.), Drocchi Mision Scientili()ue de 

 Mexi(|ue, ISSl, irt)iii (liianajuato, Mexico, is related to the present ani- 

 mal. I do not know what the spejific difl'erence is, unless it be in the 

 form of the vomerine patches, which 1 can not clearly make out from 

 I»rocchi's descrii>tion.
