ON SOME BIKDS FROM THE CONGO REGION. 



By ERNST HARTEET. 



1. Lophoceros granti sp. imv. 



AMONG some birds collected on the Annviini l»ivui- liy Mr. W. I'xmuy, of the 

 notorious Rear-Colunui of Stanley's Emin Fasha Relief Expedition, I found 

 a little Hornbill which did not agree with any description or figure, and which, on 

 comparing it with its nearest ally, Lophoceros hartlaubi (Gould), in the British 

 Museum, i)roved to belong to an undescribed species. 

 It may be diagnosed as follows : — 



Lophoceros ex affinitate specie! L. luuilaahi dictae, eadeiu furnui eandue et 

 maguitudiue, sed differt remigibus primaries et tectricibus alarum omnibus albo- 

 macnlatis, maxilla pro maxima parte rubra. 

 Huh. Aruwimi Kiver, Congo. 



The undoubtedly perfectly adult bird has the maxilla deep red, except a streak 

 towards the base along the cutting edge, which is blackish ; the mandible blackish, 

 deep red towards the tip. In L. hartlaubi the bill is blackish, and only the tip is 

 crimson. Feathers of the head blackish, a greyish white superciliary stripe from 

 the lores to the nape. Feathers of the neck blackish, edged with pale grey. Back, 

 rump, and upper tail-coverts ashy black. Primaries black, the third to the sixth 

 with a white spot on the outer web ; the secondaries outwardly narrowly edged with 

 white, and the last ones with a white spot near the tip of the outer web. Wing- 

 coverts black, with a slight metallic gloss, spotted with white near the tips. Under 

 wing-coverts dirty white, the bare bases of the shafts of the wing-qnills white. 

 Under parts ashy, dirty whitish along the middle and on the under tail-coverts. 

 TaO black, the two (inter pairs tijjped with white, the third [lair obsoletely ; shafts 

 of rectrices blackish above, whitish below. The outer pair of rectrices is more than 

 an inch shorter than the central jjair, as is the case in L. hartlaubi, but in none of the 

 other species of Lophoceros. 



Total length about 15 inches : culmen, measured over the ridge, 2-5 ; bill, from 

 gape to tip, 2'3; wing, 6-1 ; tail, 6-4 ; tarsus, 1. 



Form of bill the same as in L. hartlaubi. In L. hartlaubi no white spots are 

 present on the wing-coverts of the adult bird, and the young bird has some white 

 tips to the greater coverts only, while the bill of such immature birds is uniform 

 blackish. 



1 have named the bird in honour of Mr. W. K. Ogilvic Grant, who described 

 the Bticerotidae in the Cat. Birds B. J/., vol. xvii. 



L. hartlaubi (Gould) is only known from Liberia* and the Gold Coast. 

 Reichenow, Jonrn. f. Orn., 1877, p. 18 (not quoted in Cat. B.), quotes it from the 

 Loango coast, but as his bii'd was a pullus there seems little doubt that it does 

 not belong to the northern L. kirtlaubi, but possibly to my new species. 



This l)ird may be said to bear the? same relation to L. hartloAibi as L.jocksoni 

 Grant bears to L. deckeni.
