336 Mr. J. H. Gurney's Notes on 



British Guiana (two 

 specimens). 



Bahia (two specimens). 



Chili (five specimens). 

 Straits of Magellan. 



The genus Ictinia, tliougli included by Mr. Sharpe in his 

 '' Subfamily Falconince," is so closely allied to Eianus, that I 

 am disposed to consider it also entitled to a place amongst 

 the outlying members of the Milvine group in its wider 

 aspect^ and as connecting that group with the true Falcons, 

 and especially with the Hobbies. 



Of the two species comprised in the genus Ictinia, the 

 southern (/. plumbea) is by far the more abundant in the 

 collections sent to this country, and appears to be especially 

 numerous in British Guiana ; an interesting note on its habits 

 will be found at page 43 of Leotaud^s ' Birds of Trinidad.' 



The more northern species of the genus (/. mississippiensis) 

 is decidedly scarce in the Museums of Great Britain, though 

 it is said by Messrs. Baird, Brewer, and Ridgway^, to be an 

 " exceedingly abundant summer-bird on the prairies of 

 Southern Illinois." The same authors give as the habitat of 

 this species '^Central Mexico and Southern United States;" 

 but Mr. Salvin states that it ranges as far south as Guate- 

 mala ; and a specimen from Coban is recorded in ' The Ibis ' 

 for 1861, p. 355. 



The American authors to whose work I have just referred, 

 supply an excellent account of this species, including a de- 

 scription of its immature dress, in which stage it has not 

 been described by Mr. Sharpe. 



The ramifications of Milvine affinity extend to and include 

 some other genera, more abnormal than those which we have
