7. Descriptions of Two New Genera of Lizards (Holaspis 

 AND Poriodogaster, A. Smith, MS.). By Dr. J. E. 

 Gray, F.R.S., etc. 



(Plates XX., XXL) 



Sir Andrew Smith, M.D., having most kindly sent to the collection 

 of the British Museum two most mteresting Lizards, which he has 

 very properly named as the types of two new genera, I hasten to 

 send to the Society a short description of each of them under the 

 MS. names which Sir Andrew Smith has attached to tliem in his 

 museum. 



The first genus is allied to the family Lacertinicfce, and is at once 

 known from all the genera of that group by the pecuHarity of having 

 two series of broad band-like scales down the vertebral "line of the 

 back, which are continued on the upper surface of the base (and pro- 

 bably of the whole length) of the tail ; but the single specimen which 

 I have seen has evidently had the end of the tail reproduced and 

 covered with abnormal scales. The tail is depressed, and has a 

 series of prominent keeled scales, forming a dentated keel on each 

 side. 



This genus I consider forms a distinct family, which may be called 

 IIoLASPiD^, distinguished from iace?-/mV/<E by the form of the tail 

 and the peculiarities of the scales. 



1. Holaspis, A. Smith, MS. 



Head pyramidical, depressed ; crown covered with regular, many- 

 sided shields ; side of face shielded ; nostrils nearly on the ridges 

 near the front of a single scale with a shield in frolit of it ; labial
