bones only, the rest of the cranium being absent. So far as I saw, 

 there was no specimen that could be demonstrated to be a portion of 

 the cranium proper of one of the larger animals, although there are 

 undoubtedly small fragments of the cranial bones among the collection, 

 which has, however, not yet been thoroughly examined. The bones 

 of the pelvis were of rare occurrence, fragments of the thickest part 

 of the os innominatum, about the rim of the acetabulum, being the 

 part generally met with. In one instance, however, a very large 

 portion of the pelvis of one of the larger animals was found, consisting 

 of the greater part of one os innominatum, and the sacrum. Nearly 

 perfect specimens of large scapula) were in a few cases obtained, 

 while fragments of the scapulae of smaller animals, generally con- 

 sisting of the articular head of the bone, with a portion of the neck 

 and the coracoid process, the blade being wanting, were of frequent 

 occurrence. The remains of birds, although by no means common, 

 were often met with. 



" There can be little doubt as to the comparative age of this ossi- 

 fcrous deposit. From the presence of pebbles of Tertiary bassalt and 

 tachylite, and the fact that the whole series rests upon the Tertiary 

 basalt of the district, its origin is certainly of post-Tertiary date. The 

 thickness of the series, the occurrence in the deposit of angular, as 

 well as rounded water- worn pebbles, together with the relation which 

 the whole series bears to the general level of the country, all point to 

 the supposition that it more probably belongs to the Pleistocene than 

 to the Recent period." 



The series of specimens from those deposits shown in the Exhibition, 

 which may be taken as a fair sample of the whole, comprises various 

 remains of Procoptodon (the Macropus of Mr. Anderson), Diprotcdcn, 

 NototJierium, molars and jaws of Phascolonus, and a large number of 

 the incisors described as Sceparnodon. It will thus be apparent that 

 if Sceparnodon were a distinct genus, it would be represented only by 

 upper incisors, while Phascolonns would be equally deficient in these 

 teeth. It is further noteworthy that all the Mammalian remains in 

 the collection appear to belong to extinct genera, there being no evi- 

 dence of the numerous species of Macropus and Phascolomys, which are 

 so common in the Pleistocene of Queensland. This feature suggests 

 that the Bingera deposits are somewhat older than those of the area 

 last named. 



Seeing what an important bearing the remains from Bingera have 

 on the question of the identity of Sceparnodon and Phascolonus, I 

 requested permission from the Commissioners of the Exhibition to 

 borrow some of the specimens so named, a request which was at 

 once most courteously acceded to. 



In due course I received from the Commissioners part of the right 

 ramus of the mandible of Phascolonus, together with three imperfect
