Head small, compressed, attenuated, and swelling into a rather deep 

 thorax. Jaws long, slender, and with equally convex sui'faces above 

 and below. Snout long, slender, its tip projecting well beyond man- 

 dible, and sides not steep. Eye a trifle longer than deep, its center fall- 

 ing about last fourth in space between tip of snout and corner of 

 mouth, and its lower margin close to edge of mouth. Maxillary 

 slender, concealed, and projecting about an eye-diameter beyond 

 posterior margin of eye. Mouth large, gape long. Jaws narrow and 

 furnished with rather large and more or less equal teeth, above along 

 edges at first triserial, or for a space about f length of snout, and then 

 biserial. Vomerine teeth biserial. Mandibular teeth at fh"st, or about 

 first fifth of length of mandible, triserial, and then biserial, though 

 becoming irregular posteriorly. Anterior nostril evidently in a short 

 fleshy tube near end of snout. Posterior nostril opening in a fold of 

 upper lip about opposite anterior margin of eye. Interorbital space 

 rather narrow and convexly elevated. 



Gill-opening small and a little low. 



Skin naked and apparently smooth, without any scales. A few pores 

 on snout and head above. Lateral line apparently continuous, superior 

 along side of trunlv. 



Vertical fins only developed, low, dorsal and anal continuous evi- 

 dently around caudal? (damaged), and former inserted about first f 

 in space between gill-opening and vent.

Type, No. 33,121, A. N. S. P. Victoria. 



This species differs from the last chiefly in the biserial vomerine teeth, 

 triserial teeth in the upper jaw, and more posterior insertion of the 

 dorsal. From M. breviceps it differs in its triserial upper teeth. Like 

 Murcenichthys nicholsce Waite, Rec. Austr. Mus., V, No. 3, 1904, p. 142, 

 PI. 17, fig. 1, from Lord Howe Island, this species has a sac under the 

 throat. It differs however in the more anterior insertion of the 

 dorsal.
