314 BAZA SUMATRENSIS, Lofr.f 



throat stripe appears with age (it is much less conspicuous and 

 lighter in colour in the female than the male), and that with age, 

 also, the bands on the lower surface deepen in colour and spread 

 further up on to the upper breast. 



So little is known apparently of this species that even if in- 

 correct my hypothesis may be pardoned. 



One thing is certain, if not sumatrensis, these specimens be- 

 long to a new and unknown species,* which in that case may 

 aptly stand as Baza incognita, nobis. 



The following are the dimensions and colours of the soft 

 parts (recorded in the flesh) of the male, which I take to be 

 adult : — 



Length, 18-5; expanse, 4O0 ; tail, 9 62; wing, 13*12; 

 tarsus, 1*6; bill from gape, 1*35; straight from nostril to 

 point, 0'9 ; midtoe to root of claw, 153 ; its claw straight 

 from root to point, 0*66. Weight 16 oz. The double teeth in 

 the upper mandible very sharply cut and conspicuous. The 

 4th and 5th quills the longest ; the 3rd 0*25, the 2nd 1*15, and 

 the 1st 2*75, shorter. All the first five quills distinctly emarginate 

 on the inner web, the 2nd to the 6th emarginate on the outer 

 webs ; exterior tail feathers - 5 shorter than central tail-fea- 

 thers ; penultimate pair about 0*22 shorter than the central 

 ones. 



The tail has four dark bands, the 4th hidden by the upper tail- 

 coverts. The terminal band is 1*65, the 2nd # 76 and the 

 last visible one 0*62 broad. The first interspace is 1*15 and 

 the 2nd 067 broad. 



The legs and feet were white, slightly tinged with blue ; 

 the irides bright yellow ; the claws, upper and tip of lower 

 mandible and cere blackish ; the base of the lower mandible 

 paler. 



The forehead and a broad but inconspicuous band from the 

 latter over the eyes to the nape pale wliitey brown ; the shafts 

 darker brown ; the crown, occiput, nape and sides of the neck 

 rufescent buff, the feathers broadly centered with dark 

 brown ; the crest black, narrowly and obsoletely barred, the 

 feathers with pure white tips; the interscapulary regions and 



* I was at one time inclined to identify these birds with Lophastur Jerdoni, BIyth 

 (J. A. S. B., XI., 464 and XV. 4) from Malacca, and it is still possible that my 

 birds may pertain to this species; but he gives the wing at only 12 '5, the crest as 

 only 2'25 long and dull black ; whereas in our birds the wings are 13'1 (male) and 

 13 - 7 (female), the crest 3 inches long, glossy black, and with a most conspicuous 

 white tip, which would never have escaped BIyth. 



Mr. .Sharpe, adopting a suggestion of Blyth's, made when the latter had probably 

 never seen a skin or figure of B. Reinwardti, has identified Jerdoni with this latter, 

 but I cannot, after carefully perusing the original description, concur in this view, 

 since, in my opinion, the size of wing and general description point clearly to magni- 

 rostris. Salvadori (Uccelli di Borneo, p. 11,) says that he believes Jerdoni and 

 sumatrensis to be identical, but the absence of the pale tipping to the crest feathers 

 of Jerdoni in both adult and young, seems to me to preclude this identification.
