FROM TONKIN TO INDIA 



It possesses, however, certain species belonging to itself, of which four had not 

 hitherto been recorded, and the discovery of which is due to Prince Henry of Orleans. 

 These are inarked by an asterisk in the jireceding list, and a few words must be 

 devoted to their diagnosis. 



Criniger Henrici, n. sp. — Species near akin to that of the Crini};er i^iitturallis 

 (Bp.) of Sumatra, Borneo, Malay Peninsula, and Tenasserim, but distinguished from 

 it by a larger size, different proportions in the remiges, and by the colour of the 

 under part of the body, which is more strongly interspersed with yellow and almost 

 develops into red beneath the lower tail-feathers. The inner edges of the wing are 

 also brighter, of a yellowy or reddish white. Entire length of bird, 9.8 in. ; of 

 wing, from 3.90 to 4.5 in. ; of primary remige, 1.08 in. ; of tail, 4.33 in. ; of beak 

 (upper edge), .70 in. ; of tarsus, .82 in. 



This species is found at once in the south of Yunnan and the north of Tonkin. 

 The above description has been taken from four specimens, male and female, of 

 which one was killed on the 25th of March 1895 between Manhao and Ssumao 

 (Viinnan) on the banks of the Black River, while the others were obtained by Prince 

 Henry on a former expedition at Nam-Xong, Ban-Moi, and Hat-Hoa (Tonkin) on the 

 17th, 19th, and 25th of February 1892. 



IxuLUS Rouxi, n. sp. — Much resembles the Ixii/us flavicollis (Hodgs.) of the 

 Himalayan region in its system of colouring, but differs from it in the shade on the 

 top of the head, which is of a deep brown slightly tinged with grey and not of a 

 chestnut brown, also in its greater size and more developed wings. Entire length 

 of bird, 5.59 in.; of wing, z.55 in.; of tail, 2.1 1 in.; of beak, .39 in.; of tarsus, 

 .74 in. I have, unfortunately, only had one specimen for examination, a female, 

 killed on the 23rd of March 1895 in Viinnan, on the borders of the Ly-sien-kiang 

 or Black River. 



Chrvsomitris Ambigua, n. sp. — A most interesting form, recalling in a striking 

 manner certain Tarins of the New World, notably the Clirysomitris notata (Du Bus) of 

 Central America, by its hood of dark, almost black hue, its green mantle, the green 

 shade of yellow on the under parts of its body, the golden markings at the base of the 

 tail, and by the large yellow pattern that pervades a chief part of the remiges and 

 adorns the wings. The hood in this case, however, stops short beneath upon the 

 chin and middle of the throat, the shoulder is of a duller green and not distinctly 

 spotted with black, while the breast is instead flecked with greenish-brown ; the tint 

 on the abdomen also tends to green verging on the sides to rus.set grey, and not as 

 in the other of a brilliant yellow ; finally, the proportions are not the same as the 

 Chrysomitris notata, those of the Clirysomitris ambigua being : entire length of bird, 

 5. II in. ; of wing, 3.14 in. ; of tail, 2.00 in. ; of beak, .39 in. ; of tarsus, 3.54 in. 



Four birds of this species were killed by the Prince, namely, one female at 

 Mienning (\'unnan) on the 7th of May 1895; one male on the 13th of May 

 at Viinchou, a little north of Mienning : one male and one female on the banks 

 of the Vang-pi-kiang, an affluent of the ^lekong, on the 23rd of May. 



This species does not, however, appear rigidly confined to Yunnan, for in the 

 numerous collection of birds recently sent to the Museum by Father Dejean 

 from Tatsien-lou I have been confronted with the same Tarins, closely allied 

 to birds exhibiting the exact characteristics of the Chinese greenfinch, of the 

 Chluris sinica (L.), of which the Museum already possessed specimens obtained 

 at Pekin and at Moupin by the Abbe A. David. But what is more curious, 

 there exists in this same collection from Tatsien-lou all the transitions between 

 the specimens resembling those I have just described under the name Chrysomitris 

 ambigua and the specimens identical with the Chloris sinica of Moupin and 

 Pekin. These transitions are manifested not only in a modification of the shoulder 

 tint, which from green becomes a clear chocolate -brown, in the shade of the 

 under parts, which passes from yellowy -green to bright reddish -brown, and in 

 the fading and gradual entire disappearance of the hood, but also in a thickening
