The birds of this genus in the Society's collection bear such 

 a general resemblance to each other, that we have felt some 

 hesitation in describing them as different species. The careful 

 examination of many individuals in their own country will alone 

 determine with certainty whether they are distinct, or merely 

 varieties of the same species from age or sex. With respect to the 

 two foregoing species we have to observe that Dr. Latham, by 

 'the examination of other subjects, has been led to the same result 

 as we have been by the comparison of the specimens in our 

 collection ; and has described these birds respectively as the 

 JVedge-tailed and Cold River Goatsuckers. The chief differences 

 between them are as follows : The Pod. Stanleyanus is some- 

 what larger than the Pod.humcralis ; the colour of its plumage 

 is more purely cinereous and brown, being almost without any 

 mixture of tawny ; the external marks are more delicate, and the 

 gape of the bill is wider. The Pod. humeralis is distinguished 

 by bold black longitudinal streaks, some of which are of con- 

 siderable
