The structure of the skeleton of this species agrees in many points 

 with that of Uperodon. As well as I can deteiTnine, in a not very well 

 prepared skeleton, the general configuration of the skull is much the 

 same, but the occiput is flat and the vomerine teeth are wanting. 

 The diapophysis of the foiu'th vertebra is the longest, all the others 

 being much shorter ; the diapophysis of the sacral vertebra is not 

 quite as much dilated as in Uperodon. The structure of the extre- 

 mities is the same, and the clavicida is likewise absent, together ■wdth 

 the manubrium sterni. 



* ^ittXoos double, and neXfia sole. Fitzinger's name Siphneus is preoccupied 

 by a genus of mammals.
