370 MR. C. TATE REGAN ON THE FISHES [Nov. 28, 



I'eaehing the veitical fi-oni the anterioi' mai^gin of the eye), and in 

 having the dorsal and anal opposite one another and the caudal 

 emai'ginate. It appears to differ in the deeper body (depth 4|- in 

 the total length) and the fewer fin-rays (Dorsal 9, Anal 12). It 

 is desci-ibed from a specimen of 140 mm. from a marsh near 

 St. Kilda, Victoria.

Teeth apparently as in G. attenuatits. Depth of body 10-12 in 

 the length, length of head 7-7 1. Snout a little shorter than eye, 

 the diameter of which is 3^-3g in the length of head and less than 

 the interorbital width. Jaws equal anteriorly ; maxillary ex- 

 tending neai'ly to the vertical from the anterior margin of eye. 

 5 or 6 branchiostegals. 9 or 10 gill-rakers on the lower part of 

 the anterior arch. Dorsal 11-12 (III-IY 8-9); distance from 

 origin of dorsal to base of caudal about 3| in the length of the fish. 

 Anal 16-17 (III-IY 13-14), commencing below the origin of 

 dorsal, when laid back not extending to the caudal. Pectoral ex- 

 tending about |- of the distance from its base to the base of venti-al. 

 Yentrals 7-rayed, originating at a point nearer to tip of snout than 

 to base of caudal, and nearer to origin of anal than to base of 

 pectoi'al, extending about j of the distance from their base to the 

 origin of anal. Caudal slightly emarginate. Caudal peduncle 2g 

 as long as deep. Some small blackish sjoots on the head and on 

 the uppei- part of the body ; a line of black dots along the middle 

 of the side and one at the base of each of the unpaired fins.

Possibly this species may be based on a larval form of G. attenuatus, 

 but if so it is remai'kable that it has been recorded only from 

 South America and that larval forms of other species have not 

 been described.
