AUSTIULIAN GORIID^ :\rcCDLLOCII AND OGILP.Y. 207 



This species appears to differ from L. mordax principally in its 

 proportions, and in having fewer dorsal and anal rays. The dorsal fin 

 commences a little farther forward, and the median mandibular barbies 

 are paired on each side. 



The above proportions are those of a specimen 185 mm. long, from 

 the Richmond River. The illustration is prepared from a small example 

 92 mm. long, from an unknown locality, in which the cephalic ridges 

 are well preserved. 



Syuonyniy. — We have examined the holotype of Amhlyopna niger, De 

 Vis, and find it quite similar to the specimens described and figured. It 

 is much shrivelled and quite black, but has the cephalic ridges and other 

 characters of L. puiyurascens.

 235, pi. xiii., fig. 5. 



This briefly characterised species has not been recognised since it was 

 first secux'ed by Kent in the Cambridge Gulf, North-western Australia. 

 It is perhaps incoi'rectly associated with Trrriioides.

General form short and compressed ; body naked, but covered with 

 a thick granular mucous, which when removed, may leave small pits in the 

 skin resembling rudimentary scales. Head compressed, the profile 

 rounded ; mouth a little oblique, jaws subequal. Large tubular pores 

 open between the nostrils, on the interorbital space, behind the eye, and 

 around the preopercular border ; lower margin of the preoperculum and 

 mandible with minute papilltp. Teeth in a narrow band in each jaw, the 

 outer row of which is largest ; a few stronger inner teeth on each side of 

 the mandibular symphysis. Tongue partly free, truncate or rounded 

 anteriorly. Gill-opening opposite and as wide as the pectoral base, 

 isthmus very broad ; shoulder-girdle smooth. Dorsal with six spines and 

 about eleven rays ; anal similar to the dorsal. Ventrals small, ctip-shaped. 

 Caudal and pectorals rounded.
