448 PERNIS TWEEDALII, HUME. 



P. eelebensis, approaching, however, more nearly to the latter 

 than to the former. 



The late Mr. Blyth's description of his Pernis brachypteruz 

 may possibly have been taken from a young male of thia 

 species ; but it seems to me more probable that it represents a 

 young specimen of P. ptilorhynchus in a somewhat unusual 

 phase of plumage, and unless the type of P. brachypterus still 

 exists, it is to be feared that this question cannot be settled 

 with any certainty. 



The new species now under consideration differs from P. 

 ptilorhynchus and approaches P. eelebensis in the character of 

 the trauverse markings on the breast, abdomen, flanks, thighs, 

 under tail and under wing-coverts ; but P. eelebensis differs 

 from it in having the occipital feathers and those of the sides 

 of the neck and of the nape edged on the side of the feather 

 ■with dull rufous, and in having those of the upper breast 

 similarly, but still more broadly, edged with bright rufous, 

 the corresponding edging on the breast-feathers of the 

 Sumatran birds being partly white and partly rufous, and the 

 latter tint being much duller and less extended than in 

 P. eelebensis. 



In P. eelebensis all the upper wing-coverts are of a brown 

 color, much less inclining to black than in the case in our new 

 species, and this remark equally applies to all the dark trans- 

 verse markings of the under surface, whilst the intervening 

 light bars are pure white throughout, whereas in the Sumatran 

 and Malay birds these bars are tinged with fulvous everywhere 

 except upon the breast. 



P. eelebensis appears to be, on the average of specimens, 

 slightly smaller than the new Sumatran and Malay species, its 

 wing measurements, so far as I have observed, varying from 

 14*1 to 15*5 inches. 



[Mr. G-urney has advised me to bestow a distinct specific 

 appellation on the Malayan Honey Buzzard, which I have 

 already fully described, ante, pp. 122, 123. I have therefore 

 named it as above in memory of cne who laboured long and 

 zealously in the cause, and did much for Oriental Ornithology. 

 Owing to his repeated change of name, comparatively few 

 species bear the name he bore when taken from us, and this 

 bird, one of the very handsomest Raptors of the province 

 ■where he was first led to turn his attention to ornithology, 

 may most appropriately, it seems to me, assist in keeping his 

 memory green. — A. 0. H.J
