Differs from the preceding species in having the anterior 

 portion of the second dorsal fin replaced by a pad of fat, from 

 which the rays gradually emerge behind ; the anterior portion 

 does not contain any rays. The anal fin is composed of about 

 eighty-five rays. The nasal barbel extends to the origin of the 

 dorsal fin, none of the others reach beyond the extremity of the 

 pectoral. The eye is one-seventh of the length of the head. 

 Entirely black.

The height of the body is rather less than one-sixth of the 

 total length, and is less than the length of the head. The body 

 is compressed and tapers to the tail ; the head is rather depressed 

 with the eyes on the upper surface ; the distance from the eye to 

 the snout is equal to three diameters of the eye, and the width 

 of the interorbital space to two diameters. The lips are extremely 

 verrucose, with two prominent nasal flaps on the upper ; the teeth 

 in both jaws and on the roof of the mouth are strong, bluntly 

 conical, and distant. The barbels are very long, the nasal ones 

 reaching to the first dorsal fin. The first dorsal fin is somewhat 

 pointed and more than half the height of the body. The colour 

 seems to have been black or very dark brown. 



Long Island, Torres Straits. Length thirteen inches. 



Genus Neosilurus, Steind. 



A genus distinguished from Copidoglanis by the rudimentary 

 condition or entire absence of the anterior part of the second 

 dorsal fin. The Copidoglanis brevidorsalis, Gunth., should perhaps 

 be referred to this genus.
