been 11 mm. Behind the fifth tooth are tlie remains of three 

 smaller teeth which differ from the anterior in having so far as can 

 be seen no distinct sockets. They seem to be lodged in a grove 

 like the teeth in IchthyosciurHjX. The 6th tooth measures aatero- 

 posteriorly about 11 mm., the 7th, (S mm , and the <Sth, 7 mm. 



The vertebrae are unlike those of any S. African Permian 

 reptile hitherto discovered. The bodies are bi-concave but not 

 deeply concave. In some the transverse processes are very large 

 and pass upwards and outwards as in some of the vertebrte of 

 Belodon,. In other vertebrto the transverse processes pass outward 

 and downward as in the Pelycosaurs. The coracoid is of large size 

 and from the appearance of it, one would infer that there had also 

 been a large precoracoid. 



At present it is impossil)le to definitely assign Pelosuchus to 

 its true position, but there seems much more evidence for placing 

 it in the Diapsidan phylum than in the S.ynapsidan. Had it been 

 found in Triassic rocks one might have been inclined to regard it 

 as a primitive Phytosaur. Being a Peiiiiian reptile its affinities 

 may possibly be more with the Pelycosaurs. The vertebrae are not 

 unlike those of Anoinosauriis recently described by v. Huene and 

 regarded by him as a Pelycosaurian. Provisionally Pelosuchus may 

 be jdaced among the Diaptosaurians, and not unlikely it may prove 

 to be the representative of a new suborder.

Some years ago Mr. Alfred Brown of Aliwal Nortli discovered 

 the remains of a large reptile in Upper Beaufort beds at Kraai 

 River, The bones were believed to be those of E tis kel< /saur us uDd 

 were presented by Mr. Brown to the S. African Museum. On 

 development however it was found that they were quite unlike the 

 bones of Dinosaurs, and belonged to an animal of quite a different 

 order. 'I'he bones are in good preservation and comprise the 

 practically perfect pelvis, shoulder gii-dle, humerus, radius and ulna, 

 a num.ber of vertebra) and various fragments of other bones. 



The pelvis at once suggests a comparison with Belodon. The 

 ilium which is figured by v. Meyer as that of Belodon is so 

 strikingly like the ilium of this S. African animal that, had no other 

 bones been found, the remains would probably have been referred
