represented pure white uuderneathj vvitli (iucluding the ter- 

 minal) five caudal bands ; the other with the under-surfaee 

 plumage marked with brown droj)s^ the thigh -coverts with 

 the usual transverse bars, and the rectrices with only four 

 bands. 



Falco lathami (Tickell*, J. A. S. B. 1833, p. 569) is inci- 

 dentally alluded to in the article on Limna'etus cristatellus (T.) . 

 This is the passage : — " I shot a Hawk-Eagle in 1833-34 in 

 the jungles of Seheria, Borabhoom (Bengal), which Jerdon 

 considers may possibly be referred to this species ; but of this 

 I am very doubtful, as it was noted by me at the time as 

 only 18 inches in length. It had a fine long occipital crest, 

 black, with white tips. Head, nape, and wing-coverts clouded 

 Avith ashy and rusty. Back clouded with brown. Lower joarts 

 white, with a streak of black down the centre of the throat, 

 and with rusty bars on the breast and belly. A drawing 

 made of it at the time was lost by the sinking of my boat in 

 the Ganges ; and I have never met with the bird again, al- 

 though I often subsequently traversed and explored those 

 vast forests. ^^ 



Jerdon has suggested that F. lathami, Tickell, might have 

 been founded on a young example of L. kieneri, or perhaps 

 on Astur trivirgatus-f. The description may have been taken 



* It is not to be concluded witli any certainty, from the way Colonel 

 Tickell infa-oduces this name (I. c), that he was bestowing an original 

 title of his own on an undescribed species. The internal evidence is the 

 other way. The species is the first of the list, and is entered thus : — 

 " 1. Falco lathami. Colvj/ Falcon ? Latham ;" and then follows the de- 

 scription. The Colvi/ ( Cohy) Falcon of Latham is unquestionably B. lo- 

 photes ; and on Latham's plate (G. H. i. 1. 10) Mr. G. R. Gray had some four 

 years previously founded his F. lathami (Griff, ed. of Cuv. An. King. 

 AveSj i. p. 30). It is only at the third species in the list that Colonel 

 Tickell begins to bestow titles of his own ; and to the name of this species, 

 Falco hej-ba'cola, the following footnote is attached : — " The names of such 

 birds as have never come under my notice before, and are necessarily of 

 my own coining, I have distinguished by the addition of a T." All 

 through the paper the letter T is added to a new title ; but it is wanting 

 after the title F. lathatni. 



t L. kieiieri ad. was obtained at Oorkhia, in Singbhoom, by Colonel 

 Tickell; with A<fur fr{virgafu< he was well acquainted.
