D. bicornis I find they differ so materially as to warrant their recognition as 

 belonging to a distinct species. This may be known, after the discoverer, as 

 Diceros zvhitci, sp. nov. 



Dicer OS ivhitei, sp. nov. The humerus of this species differs most remarkably 

 from that of D. bicornis in the shape of its distal end. The olecranon fossa is 

 very much narrower than in D. bicornis, being 29 mm. in diameter, as compared 

 with 51 mm. for a specimen of the latter. Indeed, the whole bone, although evi- 

 dently that of a fully adult individual, is smaller and much slighter in propor- 

 tion to its length, which is 330 mm. from the trochlea to the head of the humerus, 

 while D. bicornis measures 358 mm. The tibia, although not differing to the 

 same extent as the humerus, is nevertheless slightly narrower in proportion and 

 a little shorter. This species is evidently a form of rhinoceros smaller and less 

 heavily built than D. bicornis. For this reason it is also distinct from D. simns. 

 and from D. simplicidcns, Scott, which is likewise larger than D. bicornis. I 

 hope shortly to publish figures showing fully the differences between the species. 



Equus sp. Several molars probably belonging to a zebra. 



Connochoctes taurinus, Burch. The basal portion of a horn-core. 



Strcpsiccros strepsiceros, Pall. An imperfect horn-core. 



Tanrofragus oryx, Pall. Portion of a horn-core. 



In addition to the above there are in the Rhodesia Museum a number of 

 bones and teeth of various other antelopes, not identifiable with certainty. 



AVES 

 An incomplete pelvis of a small bird, an ulna and several leg-bones. 



AMPHIBIA 

 The ischial portion of a frog's pelvis ; also an astragalus and calcaneum. 



FURTHER NOTES 



1908. — A second and even more detailed report on the Broken 

 Hill cave soon followed (September 26, 1908). It is a commimication 

 by Engineer Franklin White, at that time employed by the Broken 

 Hill Mining Company, to the Rhodesian Scientific Association.* The 

 paper, the title of which is " Notes on a Cave Containing Fossilized 

 Bones of Animals, Worked Pieces of Bone, Stone Implements and 

 Qiiartzite Pebbles, Found in a Kopje or Small Hill Composed of 

 Zinc and Lead Ores at Broken Hill, North-Western Rhodesia " gives 

 in the main the following information : 



The geological formation is limestone with some beds of sandstone conglomer- 

 ates and phyllites. The country in general is very flat, excepting where the 



sandstone ridges rise a few feet above the general level Around Broken 



Hill, however, there is a series of kopjes or small rugged hills composed chiefly 

 of ores of zinc and lead, the top of the highest (No. 2) being about 90 feet above
