stituting the subgenus Hydrotragus of Gray\ From Tragelaphus 

 spekii the present Antelope is at ouce distinguishable by the trans- 

 verse white markings of the body and the white spots on the head 

 and chest. In Tr. spekii the adult animal (of which, so far as I know, 

 there is no specimen in this country) is of a uniform greyish brown, 

 and altogether devoid of either stripes or " spots''^.

(Plate IX.) 



These notes relate to species of birds not included in my former 

 paper on this subject 3, and principally to those obtained during a 

 recent visit to Cosquin, a village about thirty miles from Cordova, 

 described in my ' Cameos from the Silverland,' i. ch. xv. 



[I have examined skins of most of these species in a collection 

 just received from Mr. White by Mr. E. Gerrard, jun. Where this 

 has not been done it is so stated.— P. L. S.]

A very wild bird, with an exceedingly strong pitching sort of

Iris dark-brown. 



I observed its first appearance at Cosquin on the 20th of July, 

 and then only a single individual ; but towards the end of August 

 large numbers were to be seen, mostly skimming over the water 

 of the river in places where there was a large clear surface and great 

 depth beneath.
