296 Mr. A. W. E. O'Shauglmessy on new Species of 



Scales of back narrow, elongate, smooth, in transverse rings ; 

 of belly smooth, square, in longitudinal series. A slight fold 

 along the side of the body, but without smaller scales. 



Emphrassotis simoterus, sp. n. 



Head broad, flattened above ; snout short, rounded. Ear 

 indistinct. Nostril in a single large nasal plate ; no separate 

 frenal plate, there being an oblique superficial groove, not 

 amounting to a division, in the middle of the nasal plate 

 above the small prseocular. A large anterior supraocular. 

 Internasal longer than broad ; no fronto-nasals or fronto- 

 parietals ; frontal broad, scarcely longer than internasal, not 

 touching the point of the narrow wedge-shaped interparietal, 

 from which it is separated by the slight anterior junction of 

 the two very large parietals, which are followed by two rather 

 large, transverse, postparietals ; a series of small occipitals 

 behind the inter- and postparietals. Only two pairs of post- 

 mental shields behind the large single submental. 



A slight fold along each side, but without smaller scales. 

 Scales of the back elongate, narrow, quadrangular, in trans- 

 verse series, not keeled ; those of the belly square, in ten 

 longitudinal series. Prasanal scutes 2, 5. 



In other respects this lizard resembles Proctojwrus pachy- 

 urus, Tsch., and Riama unicolor, Gray. From the first it 

 differs in the absence of a frenal plate, agreeing in that 

 character, and in having only two pairs of postmentals in con- 

 tact after the submental, with Gray's species. The absence 

 of fronto-parietals, however, separates it from both. 



Above light brown, thickly variegated with darker ; entire 

 ventral surface bluish. 



One specimen, 4^ inches in length, from Intac, Ecuador, 

 collected by Mr. Buckley, is in the collection of the British 

 Museum. 



This lizard seems to constitute a link between the Cerco- 

 sauridae and Gerrkonotus.
