668 MR. K. BROOM ON ANOMODOXT REPTILES 



The f rentals are long and narrow, and nearly shut out from the 

 orbital margins by the prjefrontals and large postfrontals. They 

 pass far backwards by the sides of the preparietal. The frontals 

 are moderately flat. 



The preparietal differs in different specimens considerably, but 

 the appeai-ance of the postfrontals, postorbitals, and parietals is 

 very constant. I give figures of the region in two specimens to 

 illustrate the variation. 



The parietals are large and broad and flanked by the post- 

 orbitals. 



In no specimen is there a tusk, but in both upper and lower 

 jaws are a few slender posterioi-ly serrated molars. The number 

 appears to vary Avith age. In a beautifully preserved lower jaw 

 there are three teeth. The first is large and is on the point of 

 being shed, the replacing tooth being seen below it. The second 

 tooth is also well developed. The third tooth is very small. 



A few years ago Haughton and I described a small skull from 

 Dunedin, which we provisionally referred to Emydops and named 

 Emydojjs platyceps. There can be little doubt that this is very 

 closely allied to the present species, and should be transferred to 

 the genus Emydopsis. 



The only striking difference between Emydopsis platyceps and 

 Emydopsis longus is that in the latter the posterior part of the 

 skull is much longer and broader, and while E. 2y^(:<'tyceps has 

 slender tusks, E. longics has none. 



The following are the principal skull measurements (in milli- 

 metres) of three specimens : — 



Type. B. C. 



Greatest length 64 68 72 



Gi'eatest width ...... about 48 about 54 about 52 



Interorbital width 12 11 12 



Intertem poral width 18 18 20 



Basal length 59 about 62 — 



Emydopsis sciuroides, sp. n. (Text-fig. 41 B.) 



The beautiful little skull which forms the type of this new 

 species was found by me at New Bethesda, the famous locality 

 which has already yielded so many interesting types. Without 

 seriously injuring the skull, it will not be possible to say Avith 

 certainty if the specimen belongs to Emydojms, but the general 

 resemblance of the skull and loAver jaAv to those of species of 

 Emydopsis is so close as to render it highly probable that the 

 specimen belongs to a species of this genus. 



The next striking characteristics of the skull are the large size 

 of the orbit and the relative shortness of the parietal region. 



The snout is short but relatively broad. A tiny corner of the 

 septomaxillary appears on the face. The maxilla is deep, and in 

 this type skull at least, tuskless. The prefrontal and lacrimal 

 are small.
