Leiuperus salarius, BcU, Zool. of the Beagle, Rept. p. 39. pi. 18. f. 1. 



Bad state. Port Desire (Patagonia). Presented by Charles Darwin, 

 Esq. The specimen is undoubtedly a half-grown Pleurodema 

 hnfontum : the form, the toes, even the lumbar gland (over- 

 looked by Prof. Bell) are the same as in that species. But the 

 condition of the specimen, the palate having been entirely de- 

 stroyed, is not such as to allow me to give a decided opinion.
