if not identical with, the Hindostan L. nigriceps (Frankl. P. Z. S. 

 1831, p. 117) . Indeed Scopoli's and Gmelin^s designations have 

 usually been associated with Franklin's on the hypothesis that 

 Sonnerat described and figured an Indian specimen ; but Bona- 

 parte's species seems to establish the existence of a Philippine 

 black-headed Shrike; and until specimens from both localities 

 are compared, it will be reasonable to presume that they belong 

 to two distinct species. 



VII. — On a recentli/ discovered Tanager of the genus Calliste. 



By P. L. ScLATER, M.A., Ph.D., F.R.S., Secretary to the 



Zoological Society of London. 



(Plate III.) 

 In the 'Journal f iir Ornithologie ' for 1866 (p. 163) Dr. Cabanis 

 has given the characters of a new species of Tanager, of the 

 genus Calliste, from Guatemala, and has done me the compli- 

 ment of proposing to call it after me, Calliste sclateri. Un- 

 fortunately there already exists a Calliste sclateri, so named by 

 Lafresnaye* (Rev. Zool. 1854, p. 207). This, it is true, is not 

 a very distinct species, being little, if anything, more than a 

 dark-coloured variety of Calliste aurulenta. But it will not, 

 nevertheless, be advisable to call a second bird of the same 

 genus by the same name; and I therefore propose to return the 

 compliment paid to me by Dr. Cabauis, and to call the new 

 Guatemalan species Calliste cabanisi. 



Knowing the interest I take in the Tanagers generally, and 

 in particular in those of the genus Calliste, Dr. Cabanis has been 

 kind enough to forward to me for examination the unique spe- 

 cimen upon which his description was founded ; and the accom- 

 panying figure (Plate III.) has been drawn from it. This 

 example is not very fully adult, as Dr. Cabanis has already 

 remarked ; but there can be no question of its distinctness from 

 all hitherto described species. It may stand as follows : —
