Animalia Nova, sive Species Novce Testudinum et Ranarum quas 

 in itinere per Brasiliam, S{c. collegit et descripsil Dr. J. B. 

 2>£ Spix. 4to. pp. 53. tabb. x\i\. S[ ^x\i. 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 

 (Matamata, 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 approximatls ; 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, 

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

 and oaePipa-y 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 graouloso ; capile brevi, 

 acute rostratoj maxilla superiore pone angulato-clevata ; 

 femoribus cum lumbis connatis ; parotidibus exiguis, vix 

 conspicuis.
