208 DESCRIPTIVE CATALOGUE OF AUSTRALIAN FISHES, 



810. Neosilurus iiyrtlii, Steind. 



Sitzgsber. Ak. Wiss. Wien. 1867, p. 14. 



I have never seen Steindachner's description of this species, 

 but I think it very probable that it is identical with a fish which 

 I have received from a river of Northern Queensland, and of 

 which the following is a description. 



First D. 1/4. Second D.4-C.+A. 115. P. 1/9. V. 13. 



Body very compressed, its height about equal to the length of 

 the head, and one-fifth of the total length ; the diameter of the 

 eye is about one-fifth of the length of the head, is contained twice 

 in the length of the snout, and more than twice in the width of 

 the interorbital space. None of the barbels reach the eye. The 

 second dorsal fin commences about one-fifth of the length of the 

 body from the tail, the rays at first are very short, but lengthen 

 gradually to the middle of the caudal fin which is pointed, the 

 rays of the anal also lengthen gradually to the tail. The colour 

 seems to have been reddish-brown, white beneath. 



River of Northern Queensland. Length seven inches. 



Genus Otcdoglanis, Gunth. 



A short dorsal fin in front, with a pungent spine ; a second 

 long dorsal is united with the caudal and anal into one fin, 

 pointed behind. Teeth in the upper jaw conical, on the vomer 

 molar-like, in the lower jaw mixed. Barbels eight or more ; 

 nostrils as in Plotosus. Cleft of the mouth transverse. Eyes 

 small. The gill-membranes are united below the throat, and 

 attached to the isthmus along the entire median line. The second 

 and third branchial arches with a series of long cartilaginous 

 processes, covering the base of the gill-lamina) on the sides facing 

 each other. Ventral fins many-rayed. 



Rivers and Coasts of Australia.
