2 Alhioi'f Miisriiin Itceortis. 



the specimen is somewluit c-i'uslied, aiul as 0^ven gives no descrip- 

 tion of i\ it is impossible to place much weight on the figui-e 

 alone. 



The lilllc slcull whicli is in th(^ Albany Museum is in fairly 



good ) icscrvation. Tluuigh the lower jaw and the maxillaries are 



badly ci-nslied and the ])remaxillai'ies lost, fortunately the 



' pbstoibital region is well presei-ved and shows the little fossil to 



have had a movable quadrate as in the modern lizards. 



In general the skull bears considerable resemblance to that of 

 the Iguanas. The orbits are unusually large and the temporal 

 fossae are rather small and almost as broad as long. The sutures 

 are fo:' the most part fairly distinct. 



The frontals are moderately fiat, and in width about one-third 

 the width of the skull. The suture between them and the 

 parietal is about opposite to the parietal foramen. The suture 

 between the frontal and the post-frontal passes almost directly 

 backwards from the inner margin of the orbit, and that dividing 

 the frontal from the prefrontal almostly directly forwards. 



The parietals, which appear to have been distinct, are together 

 about as wide as the frontals, and a little more than half as long. 

 Posteriorly they have processes passing outwards and slightly 

 backwards, and no doubt articulating with the squamosals. These 

 latter bones, however, are lost, though the impression of that of 

 the right side still remains. 



A large oval parietal foramen lies in the suture between the 

 parietals and frontals. 



The prefrontal so far as preserved does not differ from the 

 ordinary lacertilian type. 



The maxillaries are too much crushed and imperfect to admit 

 of description. They have however been moderate sized bones, 

 and lie almost entirely in front of the orbit — only a slender 

 process being sent back under the orbit. The only maxillary 

 teeth shown are detached. They are fairly long and pointed, and 

 it is moderately c«5rtain the dentition has been pleurodont. 



The jugal is a long slender bone extending iinder the whole of 

 the orbit. Posteriorly it widens out and passing upwards forms 

 with the postfrontal the postorbital arch. As in Agama there is 

 a small process directed towards the lower end of the quadrate, 

 but there is no trace of a quadrato-jugal. The tiny bone-fragment 

 shown in the figure betwetn the jugal and the (juadrate is 

 apparently a fragment of the crushed lower jaw.
