 of the mandible is liin its distance from the base of the caudal:* 

 ventral inserted below the posterior border of the eye, composed 

 of five rays, standing on a narrow Ijase, the two outer ones being 

 elongate, the others short, slender, and filiform; the second ray is 

 the longest, not quite reaching to the origin of the anal, its 

 length li in that of the head : pectoral fin pointed reaching 

 well beyond the origin of the anal, and If in the length of the 

 head : caudal fin rounded, with twenty slender, mostly branched 

 rays, and numerous short unarticulated ones, extending forwards 

 nearly as far as the dorsal and anal tins, above and below, its 

 length 8f in the total length. 



• Pale brownish-yellow, the snout, orbital ring, dorsal and caudal 

 fins, and the outer border of the anal, especiall}' near its termina- 

 tion, much darker; throat and abdomen silvery. 



This is yet another of my friend Mr. Whitelegge's Maroubra 

 Bay discoveries, the single specimen as yet known having been 

 picked up by him on the beach in a somewhat shrivelled and sun- 

 dried condition. 



Length 73 millimeters. 



Type in the Australian Museum, Sydney; register number I. 

 3655. 



Otophidium genyopus, sp.nov. 



Body moderately elongate, strongly compressed, tapering very 

 gradually to the base of the caudal fin; its depth at the shoulder 

 one-seventh of its length; head of moderate size, with the upper 

 profile very convex; its length one-fifth of the total length; its 

 depth two-thirds, its width four-ninths of its length; snout short 

 and rounded in front, projecting beyond the lower jaw, which is 



* Owing to the state of the specimen I am unable to determine m ith 

 accuracy the position and length of the longest dorsal and anal lay.s, but 

 some of those in the posterior third of the latter fin are about half the 

 length of the liead.
