The structtu^e of the sJceUton of this species agrees in many pomts 

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

 prepared skeleton, the general configiu^ation of the skull is much the 

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

 The diapophysis of the fourth 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 clavicula is Hkewise absent, together with 

 the manubrium sterni. 



* ^ittXoos double, and TreX/ia sole. Fitzinger's name Siphneus is preoccupied 

 by a genus of mammals.
