Although U. jardinei was described in 1887, its habitat was 

 unknown until 1900, when the late Mr. F. V. McConnoll received 

 an example from British Guiana — which he presented to the 

 British Museum and from which the description is taken. 



When comparing the specimen of Astur jardinei (Gurner) in 

 the collection at the Briti.sh Mu.seum, which was recorded by 

 Sharpe, Bull. Brit. Orn. CI. x. p. 5G, witli an example of 

 A. poliogaster (Temm.) in the same collection, I found that 

 the two birds were identical in colour and markings, though 

 differing in measurements, but the latter could no doubt be 

 accounted for by the difference in sex. To make certain of the 

 identity, I asked the authorities of the Xorwich Museum to allow 

 me to have the type of Uruspizias jardinei, which was kindly 

 forwarded by the Curator, Mr. F. Leney, and further comparisons
