whether A. magnirostris is the same as the Arakaii species, 

 my collection being packed up. 



Besides several birds to which are given distinctive titles 

 in this number, by Mr. Hume, '' if really new,^^* or " if con- 

 sidered distinct," &c., jEthopyga sanguinipectus, Walden 

 (Ann. & Mag. N. H. ser. 4, xv. p. 400, 1875, & B. Burma, 

 no. 494), receives the additional title of^jE. waldeni; and a 

 bird well known to ornithologists, certainly to all those who 

 consult the ordinary sources of reference before proceeding 

 to give a new title, Turdus sibiricus, Pallas (1776), finds a 

 place among the " if really new " novelties, and in its old 

 age receives the title of Turdulus davisoni, Hume. Mr. 

 Davison lately obtained it in Tenasserim, whence I also have 

 received it from Mr. Limborg, labelled " davisoni, Hume.'^ 

 In March 1874, Mr. Wardlaw Ramsay found it in Karen-nee, 

 as already mentioned by me (Blyth, B. Burma, no. 252) and 

 by Mr. Dresser (in his ' Birds of Europe ') . In the last-named 

 work it is well figured, as it had already been in Gould^s 'Birds 

 of Europe,^ and again in his ' Birds of Great Britain,' as like- 

 wise by Schlegel in the ' Fauna Japonica." 



Yours, &c.,

Sirs, — In the July number of ' The Ibis,^ in the remarks 

 upon the first part of my monograph of the Bucerotidse, now 

 in course of publication, you object to the names in the ' Spe- 

 cimen Faunulse Indicse,' given in the 'ludische Zoologie" of 

 Eorster, because he was not the author, and ask if they must 

 be necessarily adopted — or, to be absolutely correct, if Uhi- 

 noplax vigil, the name given to the Helmeted Hornbill, must 

 be accepted. It is true that Pennant is stated to be the 

 author ; and he may have produced an English version ; but 

 he never wrote a line of the work as we see it in Forster's 

 edition ; and I derive my authority for this statement from 

 Pennant himself. In the second edition of his 'Indian Zoo- 

 logy,' printed by Henry Hughs for E-obert Faulder, London, 

 1790, Pennant says that this ''work, or rather fragment"
