specimens of cr /'status in the silvery white of the forehead, chin, and throat, 

 and in the almost entire absence above of any tinge of rufous except on the 

 upper tail coverts. Length 7*1, wing 3 - 5, tarsus - 95, bill at front 5 inches.

The collection contains five specimens of Graucalus, three of which 

 answer very closely to the characters of G. Macei or G. Javensis, being 

 indeed of intermediate size and thus affording a link between the Indian and 

 Javan birds which, according to Blyth, only differ in size. They have the 

 wings white underneath, and the outer tail feathers broadly tipped with 

 white. One specimen has the abdomen slightly barred, in the others it 

 is simply albescent.

The remaining two specimens I at at first thought might be the young 

 of the above ; but closer examination convinced me that they are adults in 

 full plumage belonging to a distinct species. 



f 23. Gbattcaltts Dobsoni, n. sp. 



So far as the literature available in Calcutta has enabled me to com- 

 pare this bird with the hitherto described species of this genus it appears 

 to be distinct. I at first supposed it might be striata, J5odd.=J¥ovce-ffuine<£, 

 Gmel. &c, but it differs in several particulars from Lesson's description of 

 that species. The following is a description. 



Above dark slatey, darkest on the head ; wings and tail brownish-black, 

 primaries, secondaries and tertiaries lighter on the inner webs, faintly edged 

 with white on the outer ; two outer rectrices on each side narrowly tipped 

 with dusky white ; a black stripe from the lores round the eyes to the ear 

 coverts, thence faintly continued as a collar in one of the specimens. Un- 

 demeath white barred with black from chin to under tail-coverts inclusive ; 

 under wing-coverts similarly barred. Bill conspicuously smaller than in 

 G. Macei. Length, 102, wing, 6"2, tail, 5 - 4, bill from gape, 123, tarsus, 

 •95 inch. 



I have named the species after Dr. Dobson. 



24. Peeiceocottts speciostjs, Lath. — Gould, B. of Asia, pt. IX, pi. 4. 



A good series of this bird has been brought. It includes several young 

 males with the transitional plumage. I have little doubt that P. Aiulc- 

 manensis, Tytler, is only P. speciosus in immature plumage. It is said to 

 have " the plumage of P. speciosus with more yellow or flame-colour min- 

 gled with the scarlet. It is also apparently smaller." The amount of red 

 on the central tail feathers of this bird varies much in specimens from 

 various parts of India and Barma. Four out of five males in this collection 

 have the central tail feathers wholly black.
