they appear to be usually nearer forty tliaii fifty. We have examined a 

 photoofraph of the type of G. caiulatns, Casteluau, which is preserved in 

 the Paris Museum, and are couvinced that species also is synonymous 

 with G. hifrenatus. 



Locs. — Botany Bay and Port Jackson. Richmond River estuary, 

 northern New South Wales. Eden, south coast of New South Wales. 

 Near the Yarra River mouth, Hobson Bay, Victoria. Goolwa, Noarlunga, 

 and near Adelaide, South Australia. 



Hah. — This species has so far been recognised only from New South 

 Wales and Victorian waters. Many specimens lent for examination by 

 the South Australian Museum, prove the species to be common in the 

 estuarine waters near Adelaide also. 



[GoBius] SEMIFRENATUS, Macleay. 



(Plate xxxiv., fig. 2.) 



Gohhis semifreuatus, Macleay, Proc. Linn. Soc. N.S.Wales, v., 1S81, p. 

 598. Id., Ogilby, Cat. Fish. N.S.Wales, 1886, p. 35. Id., Waite,

D. vi/11 ; A. 12 ; P. 17 ; V. i/5 ; C. 17. About 32 scales from above 

 the base of the pectoral to the hypural joint, and about 11 between the 

 anterior dorsal and anal rays. 



Depth almost 5 in the length to the hypural joint; head 36 in the 

 same. Eye 4"6 in the head, shorter than the snout. Interoculai- space 3 

 in the eye. Snout 3'8, depth of the caudal peduncle 23 in the head. 



Form and structural details almost exactly similar to those of ^7. 

 hifrenatus, but with the scales rather more regular and somewhat larger 

 anteriorly. The posterior dorsal and anal rays are a little shorter, and 

 the caudal is less produced, the median vnya being only 0'2 longer than 

 the head. 



Colour green, white below. Snout and upper surface of the liead 

 with numerous small dark spois, which become laiger on the nape ; a 

 broad incomj)lete dark bar extends from below the aye, across the opercles 

 to the lower base of the pectoral, and terminates between the pectoral 

 and ventral bases; another imperfect bar is situated in the nuchal groove, 

 and ends in a dark shoulder-spot. An incomplete dark bar commences 

 behind the pectoral and becomes confused with a row of seven or eight 

 dark blotches on the lower portion of the sides, which are correlated 

 with some irregular transverse bars on the body. Many scales on the 

 anterior parts of the sides with opalescent sj)ots. Dorsal fins with series 

 of grey spots forming oblique rows which run forward and upward ; a 

 broad light margin to each fin. Caudal with small dark, light-edged 

 spots between tlie i-ays near the base; rarely these coalesce to form a 

 broad bar at the extreme base. Anal and ventral dusky. 



Described and figured fioni a si)ecimen 113 mm. long.
