to be a distinct species, of the same form and style of coloration as 

 that bird, but witii the sides of the body entirely olive. I propose 

 for it the name of

 I may add that this species is not the same as D. sanghirense, 

 Salvad., of whicli I have seen two examples in Capt. Wardlaw 

 Ramsay's collection.

3. DlCEUM ^NETJM, H. & J. 



Mr. E. P. Ramsay has lent me a pair of birds from the Solomon 

 Islands, and I find that the species is a very distinct one, allied to 

 D. pectorale, but distinguished by its bronzy upper surface and the 

 greater extent of grey descending on the chest, as well as the bright 

 olive-yellow flanks. 



4. Dictum tristrami, sp. n. 



The type of this new species is in Canon Tristram's collection, 

 and was obtained by Lieut. Richards in the island of San Cristoval. 

 I add a full description of the specimen, as it is not to be compared 

 to any of the other known species of Dicaeidae, belonging as it does 

 to a group by itself, remarkable for its cliocolate-browu back, black 

 tail, and hoary grey face. 



Adult Male. General colour above chocolate-brown, the mantle 

 slightly streaked with a few hoary whitish margins to the feathers ; 

 wing-coverts darker chocolate-brown than the back ; bastard-wing, 

 primary-coverts, and quills blackish brown ; the inner secondaries 

 chocolate-brown, contrasting sharply with the back ; head brown, 

 but mottled with blackish-brown centres to the feathers, the plumes 

 of the forehead and vertex mai-gined with hoary white, the latter 

 slightly mottled with brown bases ; lores, eyelid, fore part of cheeks, 

 and base of chin blackish ; hinder cheeks, throat, and fore neck
