ALLIED PETREL. 
Of course, this description, which has given so much trouble, can only be 
construed as a nude name, no coloration whatever of the body of the bird 
being given. 
In the Synops. Birds Austral., Pt. iv., App., p. 7, 1838, Gould introduced 
his Puffinus asshnilis as follows : — 
Crown of the head, all the upper-surface, wings and tail sooty-black ; sides of the face, 
throat, and all the under-surface white ; bill dark horn-colour ; tarsi and toes greenish- 
yellow ; webs yellowish-orange. 
Total length, 11 inches ; biU 2| ; wing 6| ; tail 3 ; tarsi 1|. 
Habitat, New South Wales. 
The measurements, as usual with Gould’s figures, are not accurately given.
