with that species in the distribution of the black and blue colours ; the latter, however, 

 instead of being purplish, is of the most brilliant silvery turquoise-blue. I have named 

 tbis species, which bears the same relation to I. puella that I. turcosa does to I. cyanea, 

 after Lord Tweeddale, who has so carefully worked out the species of this genus, and 

 to whom we are indebted for his most excellent paper on the birds of the Pbilippines.

a. cJ • Negros. Eyes hazel ; a yellow ring round the eye. 

 The combination of an eye-wattle and a crest seem to me to indicate that this bird 

 should be placed in a distinct genus from JPycnonotus or Otocompsa ; and I therefore 

 propose the name of JPoliolophus. The colouring of the bird is very badly rendered 

 in the plate accompanying Lord Walden's paper — the greyish crest not being defined, 

 and the eye-wattle entirely omitted.

77. Criniger erateb, sp. n. 



<j ad. affinis C. gutturali, sed pectore ochrascenti-flavo et subcaudalibus ochrascentibus 

 distinguendus. Long. tot. 8'3, culm. 0-95, alse 4-0, caudse 37, tarsi 0-85. 

 a. c? . Puerto Princesa, Palawan, July 1874. 

 This new species is very closely allied to two others, viz. O. gutturalis and C. gularis, 

 all of them having brown heads and olive-green backs. It differs from C. gularis in 

 being larger, with a longer beak, and in having the under surface from the throat 

 downwards ochraceous yellow, , varying towards pale fawn. Other characters are the 

 brown tail with olive-green edges, and the greyish white cheeks with silvery white 

 shaft-streaks. In C. gularis the ear-coverts are uniform ashy brown, the tail is dull 

 chestnut-red with pale ochraceous brown edgings ; the under surface, with the excep- 

 tion of the throat and fore neck, is bright yellow, including the under tail-coverts. 



To C. gutturalis the Palawan bird is very similar, but it differs in the colouring of the 

 under surface. C. gutturalis has the chest ashy brown washed with olive, the under 

 surface pale yellowish with tawny under tail-coverts ; O. f rater has the throat white, 

 and the entire rest of the under surface ochraceous yellow, including the under tail- 

 coverts. The flanks in both birds are olivaceous, and they are both alike in the grey 

 facial markings and the white -streaked ear-coverts.
