Fig. 11. Embryo of the same age as fig. 8, turned round and much com- 

 pressed, so as to exhibit the anterior whip of cilia and the large 

 aperture behind the vibratile ring, X 350 diams.

XII. — Descriptions of jive new Species of Birds from Queens- 

 land, Australia ; and a new Humming-bird from the Ba- 

 hamas. By John Gould, F.E.S. &c. 



Eopsaltria leucura, Gould, n. sp. 



Forehead, lores, and a line nearly surrounding the eye and 

 the ear-coverts black ; head and upper surface dark leaden 

 grey, fringed posteriorly with greyish white ; wings blackish 

 brown, darkest on the shoulders ; upper tail-coverts black ; 

 two centre tail-feathers black ; the next on each side black, 

 with a stripe of white on the basal part of the shaft and outer 

 web ; the remaining four on each side white at the base, and 

 black for the remainder of their length ; all the under surface 

 and the under tail-coverts white, with the exception of a broad 

 band of pale grey across the breast ; bill and feet black. 



Total length %\ inches, bill -j-§-, wing 3j, tail 3, tarsi 1. 



Habitat. The Cape- York district. 



Remark. This is the largest species of the genus yet dis- 

 covered ; it is somewhat allied to the Eojysaltria leucogaster of 

 Western Australia, but is distinguished from that and every 

 other known species by the white at the basal portion of the 

 lateral tail-feathers. 



I have for a long time entertained a belief that there is yet 

 another undescribed species of Eopsaltria inhabiting Queens- 

 land and the eastern portion of New South Wales — in other 

 words, or to make the matter more clear, that there are three 

 yellow-bellied species resident in the southern and eastern 

 portions of Australia. If this opinion be correct, I have com- 

 mitted the error of figuring the undescribed one in my folio 

 work on the birds of that country under the erroneous specific 

 appellation of australis. 



The three species may be thus defined : — 



Eopsaltria australis. 



Crown of the head, nape, and ear-coverts grey ; rump dull 

 wax-yellow ; chin greyish white ; under surface bright yellow.
