for which the term Aulea * (taken from Dr. SchifFs MS.) has been 

 already published by Prince Bonaparte. It forms, in fact, an excellent 

 second species of this division, which seems to serve as a connecting 

 link between the genera Lipaugus and Heteropelma, and is perhaps 

 worthy of generic rank.

 Mus. P. L. S. 



I obtained a single specimen of this Tinamou out of a large col- 

 lection of Bogota skins in the hands of a dealer. I have in vain 

 attempted to find a name for it, and have looked through the ex- 

 amples of these birds in the great Museums of Leyden, Paris and 

 Philadelphia without finding a similar one. In the British Museum, 

 however, is a specimen possibly referable to the young stage of this 

 species. 



The present bird agrees in size and shape tolerably well with T. 

 parvirostris and T. tataupa, but is quite different in colouring from 

 any member of the group with which I am acquainted. 



3. On the Duiker Boks in the Society's Gardens. 

 By Dr. J. E. Gray, F.R.S., F.L.S., V.P.Z.S. and Ent. Soc. 



(Mammalia, PI. LVII.) 



In the text to the ' Knowsley Menagerie,' and in the ' Catalogue of 

 the Hoofed Quadrupeds ' in the British Museum, I divided the 

 Duiker Boks into three species. The distinctness of these species 

 has been doubted. 



As there is now in the Gardens of the Zoological Society speci- 

 mens of two of the species, and as each of these has bred there, I 

 considered that it might be advantageous to give a figure of the male 

 of each species, side by side, on the same plate. 



1. The Impoon, Cephalophus Grimmi, Gray, Catalogue, Ungu- 

 lata, p. 78, orbit and beneath white. There are in the Gardens a 

 female and three young males. 



2. The Burchell's Buck Bok, Cephalophus Burchellii, Gray, Cat., 



* Prince Bonaparte writes this word ' Aulea,' but if, as I suppose is the case, 

 it comes from ai)\bs, tibia, the proper adjectival form would be aulius.
