184 Mr. J. Gould on new Sptecies of Toucans. 



Aulacorhamphus erythrognaihus. 



Base of the upper and hinder half of under mandible clear 

 uniform light chestnut-brown ; the remainder of the bill 

 clouded with black, with horny tips to both mandibles. 

 Entire plumage green except the throat, which is light blue- 

 grey ; a blue wash also pervades the six middle tail-feathers ; 

 over the eye a narrow line of blue, and also a spot of the 

 same colour on the cheeks next the bill and beneath the naked 

 skin round the eye, which is reddish brown ; legs green. 



Total length 12 inches, wing 4^, tail 4f, tarsus 1£, bill 2^. 



Ilab. Caripe, Venezuela. 



Remark. It is now many years since the late Jules Verreaux 

 presented me with a specimen of this little toucan, which 

 he considered quite distinct from any known species. In the 

 collection of Mr. Salvin there exists another example, sent, I 

 believe, to this country by Mr. Goering. If this bird be 

 compared with its ally A. sulcatus it will be found small in 

 size, while the bill is deep, short and robust, and not so deeply 

 channelled on the sides. The tail is perhaps shorter than in 

 other species of the family. 



Aulacorhanvph us ph ceo Icemus. 



General plumage deep grass-green, the green inclining to 

 yellow on the flanks and to blue on the tail ; throat deep greyish 

 blue ; a narrow stripe of blue surmounts the eye, and there is 

 an almost equally narrow line of blue beneath the bare space 

 at the base of the bill ; culmen of the upper mandible yellow, 

 except at the hinder part next the head, which, with the re- 

 mainder, is black ; under mandible black, with a deep-chestnut 

 base ; both mandibles, however, have a broad white line next 

 the face ; vent and all the tail-feathers tipped with chestnut- 

 red ; on the last feather the green runs up to the end on the 

 outer margin, but not so on the rest ; a conspicuous narrow 

 yellow line occupies the front of the shoulder — a mark which 

 is observable in other species, but much less conspicuous 

 than in the birds here described ; legs greenish. 



Total length 13 inches, bill 2$, wing 5, tail 5^, tarsus 1§. 



Hob. Concordia, in Columbia, and Merida, in Venezuela, 

 from both of which localities I have examples in my collec- 

 tion — those from Concordia sent by Mr. Salmon, that from 

 Merida by Mr. Goering. 



The nearest ally to this bird is the A. albtwlta, a bird 

 with a white throat.
