I have taken the young of this species and brought them up from 

 the time when their eyes were shut to the time when they were fully 

 fledged. I may mention that their eyes do not open for some days. 



As a rule, this little barbet laj^s three eggs, and sometimes only two ; 

 butj on the other hand, it does sometimes lay as many as four, as I have 

 taken this number of young. Sometimes when there are four eggs 

 they seem to be laid in pairs, as I once took two hard-set eggs and 

 two young, and, another time, four young birds of two distinct ages. 



Twenty-four eggs average '2&' X '70". The greatest length and 

 breadth is 1*07" and '83" and the least, either way •85"and 'Bo". Most 

 eggs are rather long ovals, but others are very broad. 



(401) Cyanops eobustikosteis. — The Thick-billed Barbet. 

 {Spec, nov.) 



Whole plumage green, brightest and tinged with yellow on the 

 forehead ; visible portions of the wing rather dull grass-green ; the 

 coverts tinged with yellow on the outer webs ; quills dark brown on 

 the inner webs and next the shaft on the outer webs ; the secondaries 

 edged pale yellow-cream on the inner webs ; tail below dull blue- 

 green. Whole lower plumage rather bright but pale grass-green, the 

 lores, cheeks, ear-coverts, throat and upper breast strongly suffused 

 with blue ; the remainder of the lower parts rather less so, the under 

 tail-coverts being quite free from this colour. 



Irides orange-brown ; orbital skin dull blue ; bill horny-black tinged 

 with yellowish-horny at the base; legs pale slate, claws almost black. 



Length 5-4" ; wing 3-25" ; tail 1-70" ; tarsus -75" ; bill at front -65", 

 and from gape '98", breadth at forehead '36". 



For a long time I considered this bird to be merely a young 

 C. cyanotis to which it bears a very strong resemblance, but on getting 

 some nestlings of C. cyanotis I was surprised to see the dark forehead 

 very distinctly developed, and these same nestlings, when full grown, 

 had the forehead almost as dark as in the adult bird, although none 

 of the bright colours had begun to show. In these birds the bill and 

 feet were still unmistakably those of very young birds. Comparing 

 my bird with these young ones, I then found other differences were 

 as follows : — 



In the first place, my bird, which showed by its feet and bill that it 

 was at least fully adult, had no trace of any dark forehi:ad but, on the
