privilege of perpetuating the remembrance of the benefactors of their 

 science, and especially of those who have contributed largely to the stock 

 of materials from which information is derived ; — a privilege which 

 assuredly should be exercised charily, and with due judgment and 

 discrimination ; such as would really render it an honorable and covet- 

 ed distinction, and be understood to serve for a lasting memorial and 

 acknowledgment of services that had been done for science. 



Iora, Horsfield. In J. A. S. XIII, 380-1, I indicated three de- 

 scribed species of this genus, which had been erroneously considered 

 identical; but at the time of writing that notice, I was acquainted only 

 with the female of I scapularis, which alone is figured and described 

 by Dr. Horsfield. Both this and /. typhia are common in the vicinity 

 of the Straits of Malacca — the male I. scapularis having the throat 

 and fore-neck dark green, uniform with the upper parts, and no yellow 

 except on the orbital feathers. According to Mr. Strickland, Dr. Hors- 

 field has lately obtained a new Iora equal in size to the small Orio- 

 lus xanlhonotus ; and Mr. Strickland regards this approximation of 

 size as tending to corroborate his opinion that the genus Iora is allied to 

 Oriolus, — an opinion to which, however, with all deference, I do not 

 feel disposed to accede. To the synonymes of /. zeylonica (which speci- 

 fic name was based on the Ceylon Blackcap of Brown's Illustrations,) 

 must be added Muscicapa melanictera, Gm., founded on Brown's Yellow- 

 breasted Flycatcher, also from Ceylon. 



Chrysomma, Hodgson : founded upon Timalia hypoleuca, Franklin, 

 v. T. Horsfieldi, Jardine and Selby. With reference to Mr. Frith's 

 statement {J. A. S. XIII, 360,) of there being a second species of 

 this form in Bengal, differing from the common one in being about half 

 larger, I may remark that Chr. hypoleucos is subject to some variation 

 of size, and especially of depth of colouring, more particularly upon the 

 crown ; some having this part dusky-vinaceous, with a tinge of the same 

 on the rest of the upper parts, while others have the whole upper parts 

 paler, and of an uniform rufescent-brown, brightest on the wings : the 

 latter, however, appear to be younger birds, and certainly are not dif- 

 ferent in species from the dark-headed ones. Chr. hypoleucos appears 

 to be very generally diffused throughout India.
