DEKDRERPEIID-E. 171 



narrower than in the preceding species, with nearly straight lateral 

 margins. The generic reference is provisional. 

 Hob. Europe (Bohemia). 



R. 1449. Electrotype from a fragment of shale, showing the frontal 

 aspect of the cranium. The original is the type, and was 

 obtained from the Gaskohle (Lowest Permian) of Nyfan 

 (Pilsen) ; it is figured by Eritsch in his ' Eauna der Gas- 

 kohle,' vol. ii. pi. li. fig. 1. Purchased, 1888. 



The three following genera are very imperfectly known, hut approxi- 

 mate in the more or less parabolic figure of the skull to Dendr- 

 erpetum ! . The imperfect young skeleton noticed below (p. 172), 

 under ih?. name of Platyceps, appears to have rhachitomous 

 vertebras, but this may be merely a feature of immaturity. If 

 the vertebras of the adult were fully ossified, it is not improbable 

 that these genera should be included in the Dendrerpetidse. 



Genus BRACHYOPS, Owen 2 . 



Skull very broad ; orbits situated far forwards, large, oval, con- 

 verging anteriorly, and separated by a very wide interorbital bar ; 

 nares apparently small. Cranial sculpture faintly radiate ; an indis- 

 tinct lyra present. 



BracLyops laticeps, Owen 3 . 



The type and only known species. Of considerable size ; skull 

 rather broader than long, with a rounded muzzle, its total length 

 being 0,107 (1*25 inches), and its greatest width 0,121 (4-75 

 inches. 



Hob. India (Central Provinces). 



R. 1737. Cast of the imperfect cranium. The original, which is 

 preserved in the Museum of the Geological Society, was 

 obtained from the Mangli stage of the Lower Gondwanas 

 near Mangli, a small deserted village lying at the northern 

 extremity of the Wardha Gondwana basin, about 50 miles 

 south of Nagpur, and 35 north-west of Chanda. It is 

 figured by Owen in the ' Quart. Journ. Geol. Soc' vol. xi. 



1 Compare Owen's figure of the skull of Brachyops with that of Bendrerpetum 

 foveolatum, given by Eritsch in his ' Fauna der Gaskohle,' vol. ii. p. 9, fig. 126.
