W(41 preserved spocimen ineasui-e 24 mm. in h^ngtli. They are 

 distinctly convex, l»nt <lo not form siipranasal protuberances such 

 as are frequently i)re«ont in Anoiiiodoiiti^. The maxillary bone is 

 somewhat quadi-angular in shaj)e. In the type specimen it 

 contains a lai-ge tusk which is directed downwards and forwards; 

 wliere it leaves the bone it measuivs 7 mm. in its autero-posterioi' 

 diameter. A considerable number of the specimens liave tusks of 

 similar size, but a numlxM- of otliers have slender tusks of from 

 4 to 5 mm. in diameter. The small tuskeJ forms are apparently 

 as mature as the large tusked forms, and we are probably justified 

 in regarding the difference as sexual. The small tusks are directed 

 downwards and forwards, exactly as are the large ones. 



The orbit in the type specimen measures 29 mm. antero-pos- 

 terioi-ly and 28 mm. vertically, and the iiiterorbital width is 21 

 mm. Immediately below the orbit the jugal l)one measures 5 mm. 

 in depth, but it becomes rapidly deeper on passing l)ackv;ards, 

 and at the post orbital bar it measures 17 mm. Here it is over- 

 lapped by the squamosal which is about as deep. Th<^ jngal passes 

 l)ack behind the scjuainosal as far as the plane of the parietal fora- 

 men. There is a well-developed prei)arietal bone. 



The lower jaw has the angular with the remarkable fan-shaped 

 expansion seen in well-preserved Oudenodon skulls. This is a 

 character which will probably be found in all AnoDiodonts, though 

 usually lost in museum specimens. 



ProcoJoplton Baini, n. sp. 



This new species is founded on a specimen discovered hy Mr. 

 T. Bain, and presented to the South African Museum by his son 

 Mr. J. M. Bain. The specimen is in a matrix of soft grey sand- 

 stone ; its localit.y is unfortunately unknown. It consists of 

 the fairly well preserved skull, the left scapula, the left manus 

 and pes, radius, ulna, tibia and fibula, a few I'ibs and abdominal 

 ribs. 



The skull is chiefly i-emarkable for the complete absence of 

 a quadrato-jugal horn. There are 4 premaxillary teeth and 8 

 maxillary ; and in the lower jaw probably 11. In Procoloplion
