 of the Geology of India,' pt. i. p. 131. 



Made in the Museum. 



Genus BOTHRICEPS, Huxley \ 



Syn. (?) Platyceps, Stevens 2 . t 



Skull more elongated than in the preceding genus ; orbits placed 

 near the middle of the skull, and the width of the interorbital bar 

 only slightly exceeding that of the orbit; nares large. Epiotic 

 cornua long and narrow. Cranial sculpture closely and irregularly 

 pitted. 



It is highly probable that the flattened skeleton of a small Laby- 

 rinthodont described and figured as Platyceps wilJcinsoni, Stephens 3 , 

 belongs to a very young individual of a species of this genus, in 

 which the skull has its width somewhat increased by pressure, 

 although (as in Archegosaurus) it was relatively wider than in the 

 adult. 



Bothriceps australis, Huxley 4 . 



The type species. Rather smaller than Brachyops laticeps, the 

 extreme length of the skull being 0,095 (3*7 inches), and its greatest 

 width about 0,095 (3*7 inches). Skull relatively wide, with a 

 blunted muzzle. 



Hab. Australia. 



23110. The skull, wanting nearly all the cranial bones ; from Aus- 

 (Fig.) tralia. The type specimen ; described and figured by 

 Huxley in the ' Quart. Journ. Geol. Soc' vol. xv. p. 647, 

 pl. xxii, fig. 1. This specimen was doubtless obtained 

 from the Hawkesbury beds of New South "Wales. The 

 contour of the epiotic cornua is lost. Purchased, 1848. 



Bothriceps huxleyi, Lydekker 5 . 



Smaller than the preceding species, with a narrower and more 

 pointed skull (fig. 41). In typical specimens the extreme length of 

 the skull is about 0,065 (2-6 inches), and its greatest width 0,062 

 (2*45 inches).
