Animalia Nova, sive Species Novce Tesiudinum et Ranarum quas 

 in itinere per Brasiliam, Sfc. collegit el descripsit Dr. J. B. 

 deSpix. Ato,pp. bZ. tahb,x\\\. Si xx\\, Monachii. 1824. 



The number of new species of Testudinous Animals described 

 in the present work amounts in the whole to eighteen, eleven of 

 which are referred to the genus Emys, one to that of Chelys 

 (Matamatay Merrem), two to Kinosternon N. G., and the re- 

 maining four to that of Testudo. The characters of Kinosternon, 

 which appears to have been formed with the view of comprehend- 

 ing the Box Tortoises, the Terrapence of Merrem, are as follows : 



Structura Emydis, pectore modo cataphracto; maxillis et capite 

 supra inter oculos nudo squamosis ; rostro pernasuto ; oculis 

 minus approximatis ; gula subtus multicirrhosa ; cauda apice 

 unguiculata; bracteis pectoris undecim, illis pectus inter et 

 testam interjacentibus non connatis ; palpebris transversis. 



In the Frogs the number of new species collected is yet more 

 considerable. They consist of eleven species of the genus Rana, 

 Iwenty-three of Hyla, twelve of Bufo, six of Oxyrynchus N. G., 

 and one Pipa ; in all fifty-three : a most important acquisition in- 

 deed, when we consider that the whole number of these animals 

 described by Merrem does not exceed seventy-one. The follow- 

 ing are the characters by which M. Spix distinguishes his genus 

 Oxyrynchus. 



Corpore bufonino, non verrucoso sed granuloso; capite brevi, 

 acute rostrato ; maxilla superiore pone angulato-elevata ; 

 femoribus cum lumbis connatis ; parotidibus exiguis, vix 

 conspicuis.
