the coracoid from that external to it much more convex and more 

 prominent, but without a raised hmiting hne of muscular attach- 

 ment ; oblique ridges on visceral surface of coracoid less regular, 

 less continuous, and less numerous, thinner, and more sharply 

 raised ; entepicondyle not prolonged distally so as to give the end 

 of the humerus a squarish appearance ; the trochlea radialis com- 

 parativel}^ small ; shaft of femur stouter ; linea aspera somewhat 

 less pronounced ; depth across the outer condyle of the distal end 

 of tibia much less, the two condyles of nearly or quite the same 

 length ; bridge over the tendon of the extensor digitoriiin connminis 

 muscle much narrower. 



Type Locality. — Lower Cooper's Creek, Lake Eyre, South Aus- 

 tralia. 



Geographical Distribution. — Vicinity of Lake Eyre, South Aus- 

 tralia. 



The remains which formed the basis of the description of this 

 species consist of coracoid, humerus, radius, ulna, femur, tibia, 

 tarsometatarsus, and vertebra ; and represent a bird somewhat 

 heavier than Chenopis atrata. They were found in the Pliocene or 

 Lower Pleistocene formation at the following localities about Lake 

 Eyre : — Lower Cooper's Creek, Malkuni, Kalamurina, Wanka- 

 maminna, L^nduwumpa, and Wurdulumankula. 



A Trip to the Upper Hunter River District, New 



South Wales.

To be first in the field of discovery is one of those prizes that 

 await naturalists, explorers, and scientists who go ahead to 

 make the path easy for those who follow ; generally speaking, it 

 is the only prize, yet to those who win it the knowledge of being 

 first on untrodden paths has a value not measured by a money 

 standard. In the naturalist's field it is not easy in these days to 

 occupy this enviable position, for the world is not as wide as it 

 was ; and therefore the next best thing is to follow in the track 

 of our earlier leaders, tracing step by step the course of their 

 investigations, and marking note by note all that they saw and 

 recorded. 



Such was my pleasant lot when, during a recent visit to the 

 valley of the Upper Hunter, New South Wales, I was fortunately 

 enabled to go over the very ground traversed in 1839 and 1840 

 by the late famous ornithologist, Mr. John Gould, F.R.S., &c., 

 London, from which he secured so many interesting specimens. 

 The Brisbane mail train often carried me to certain happy hunting 

 grounds near Ourimbah, on the Northern line, situated about 60 

 miles from Sydney and some 5 or 6 miles from the coast-line. It 

 is a belt of country timbered with dense sub-tropical forest, offering 

 a splendid field for research, and has become familiar to me in
