length from the tip of the snout 2| in that of the head. Anterior 

 nostril with a raised rim, which forms a flap behind; posterior an 

 ov^al foramen some distance in front of the middle of the eye. 

 Teeth in the jaws fine, acute, and cardiform, of equal size, and 

 directed slightly backwards ; premaxillaries densely toothed ; 

 maxillary and mandibular bands triserial anteriorly, gradually 

 narrowing to a single series posteriorly; vomerine teeth continuous 

 with the premaxillary, those on the shaft short, stout, and conical, 

 biserial in front, uniserial behind. Gill-opening rather small, the 

 length of the slit about |^ of the width of the isthmus and less 

 than k the diameter of the eye. Vent well in advance of the 

 middle of the length, its distance from the extremity of the 

 snout 1^ in the length of the tail. Dorsal and anal fins wel- 

 developed, the former commencing above the base of the pectoral, 

 the space between its origin and the tip of the snout 54 in the 

 total length and 2| in the body ; pectoral well developed, pointed, 

 its length 2| in that of the head and li in the gape. Uniform 

 pale yellow ; {fijieusis, a native of the Fijian Seas.) 



There is a single specimen of this leptocephalid in the museum 

 of the Sydney University, which was collected many years ago 

 by Mr. A. J. Boyd and measures 152 millimeters. 



A second species has been described from the Fiji Group by 

 Dr. Giinther under the name gnitulata; compared with the 

 present species it will be seen that the head is longer in comparison 

 with the trunk and the body much shorter as compai-ed with the 

 tail: the eye is also smaller.
