dark brown rectrices, with very narrow pale borders to the 

 outer webs, a slight alar band of dull white, shows no white 

 on the parapteral feathers, and has smoke-coloured under 

 wing-coverts ; it inhabits the great rivers of South America 

 which drain from the Andes (ascending to the cataracts), 

 and also the Pacific coasts of Chile, Peru, and Ecuador, On 

 the coast of South Brazil and Argentina, ascending the 

 Parana and Paraguay to their head-waters, is found a 

 species which chiefly resembles the northern R. nigra, but 

 differs from it in having a smaller alar band, and the rec- 

 trices chiefly browa, with broad white edges to the outer 

 webs. This he proposed to call 



Rhynchops intercedens, sp. n. 

 ^ . Similis R. nigrce, sed fascia alari alba angustiore, et rec- 

 tricibus prsecipue brunneis, late albo marginatis distin- 

 guenda. Long. tot. 18 poll., alae lo'25. 



The Hon. Walter Rothschild sent for inspection a new 

 species of Bower-bird, which he characterized as follows : — 



-itElurcedus jobiensis, sp. nov. 



Tbis species is nearest to ^. melanocephalus , Ramsay, from 

 British New Guinea, but shows suflBcient diflFereiices to 

 justify its separation. The head is black, uniformly spotted 

 with huffish yellow, and does not show the black band on 

 the sides of the occiput, so conspicuous in /E. melanocephalus. 

 Upper neck and back brownish buff, with black margins. 

 Ear-coverts consisting of the large patch of bristly feathers 

 found in its three nearest allies, but this patch passes straight 

 into the black of the throat, without any marked area of 

 pale feathers surrounding it, as in ^.-E. melanot.is, zE. melano- 

 cephalus, and ^. arfakianus. The pale spots on the tips of" 

 the wing-coverts not very distinct, and of a dusky buflF colour. 

 Throat, Breast, and uppermost part of abdomen black, with a 

 small central buflf spot in each feather, while in jE. melanotic 

 (from the Aru Islands] and jE. melanocephalus these feathers 

 are buff or whitish, with narrow black borders. The breast 

 is much greener in jE, arfakianus from Z\It. Arf'ak. Lower
