VII. — Description of a new Species of Skink. By A. W. 

 E. O'Shaughnessy, Assistant in the Natural History 

 Department of the British Museum. 



Cophoscincus obscurus, sp. n. 



Body tetragonal ; tail thick, round. Internasal veiy large, 

 covering the upper surface of the snout, concave posteriorly. 

 Frontal narrow, triangular, rounded anteriorly; fronto-parietals 

 separated ; supraorbitals five, the fifth very small ; frenal 

 rather large, almost quadrangular, with the front upper angle 

 pointed. Supralabials six ; infralabials four, narrow and long. 

 Ear-opening none. Lower eyelid not transparent. Fifty- 

 two scales in a longitudinal dorsal series, fifty in a ventral 

 one ; twenty-two'^ scales in a series round the body ; those on 

 the back larger. Number of scales between fore and hind 

 limbs about thirty-four. Preanal scales larger. Limbs small, 

 toes short. 



Colour brown, with rows of black dots along the dorsal 

 series of scales, and a dark streak from the eye along the 

 upper lateral margin of the body to the tail. 



This species evidently resembles closely the Lygosoma 

 scuiirostrum, Peters (Monatsber. Akad. Berl. 1873, p. 743), 

 but differs in the number of scales between the fore and hind 

 limbs, and in having no external ear. 



Queensland. One specimen in the British Museum.
