Eleotris grandiceps, sp. nov. 

 D. 7 1/9. A. \. L. lat. 38 to 40. 



Twelve series of scales between the origin of the posterior dorsal 

 fin and the anal. Head very large, broad, depressed, without any 

 apparent scales ; lower jaw prominent ; teeth villiform. The height 

 of the body is contained five times in the total length, and that of 

 the head three times and a half. The diameter of the eye is one- 

 fifth of the length of the head, and nearly one-half of the interorbital 

 space ; the pectorals reach to the origin of the anal fin. General 

 coloration yellowish, punctured with black in particular on the upper 

 part and sides ; snout blackish ; lower jaw sometimes punctured with 

 black also ; beneath whitish. Anal papilla very small. Total length 

 3|^ inches. 



Hub. Upper Hawkesbury River ; freshwater lagoons near Bronte 

 and Richmond, Eastern Creek, and other tributaries of the Hawkes- 

 bury. 



There are just twelve species of fishes from the Nepean and 

 Hawkesbury ; but I am assured by Mr. George M. Pitt, jun., to 

 whom I am chiefly indebted for my specimens, that the river con- 

 tains more than twenty different kinds of fish : the remaining spe- 

 cies I hope to capture during the course of this summer, and I 

 shall furnish an account of them in due time. Of our northern 

 rivers the Hastings, the Richmond, and the Clarence I know but 

 little ; that they team with fish there is no doubt, and that many 

 new genera and species will be found amongst them is certain. 

 Many of the settlers upon the banks of these streams have pro- 

 mised their cooperation; and Mr. James F. Wilcox, who resides 

 on the Clarence River, has supplied me already with many inter- 

 esting specimens. I received from him Oligorus macquariensis, 

 Cuv. & Val., Therapon unicolor (?), Galaxias scriba, Rich., Eleo- 

 tris mogunday Rich., and E. compressus, sp. nov., which may be 

 described as follows : — 



Eleotris compressus, sp. nov. 



D. C. I to 10. A. ^. L. lat. 28/30. 



Eight series of scales between the origin of the posterior dorsal fin 

 and the anal. Body cyprinoid, compressed ; the height of the body 

 is contained three times and three-quarters in the total length, and 

 the head four times ; the horizontal diameter of the eye is one-fourth 

 of the length of the head, and is contained once and a half in the 

 interorbital space ; the snout is short, lower jaw longest ; mouth 

 rather small ; head scaly. 



Coloration reddish brown, with five or six indistinct cross bands, 

 formed of the close-dotted black spots with which the scales are 

 covered. The second dorsal and the anal are rather long, and more 

 or less marked with black at the base and top ; besides this, the hinder
