AUSTRALIAN GOBIID^ McCDLLOCH AND OGILBY. 219 



fins are dark, with some still darker spots on the rays; the anal has a 

 light boi'der. Pectorals and ventrals light coloured, the former with grey 

 spots. 



Described and figured from a specimen 85 mm. long from Port 

 Jackson. 



Variation. — A large number of specimens from Port Jackson, South 

 and South-west Australia, prove this form to be variable in colour ; the 

 southern specimens are very dark with their markings obscurely defined, 

 while those from Port Jackson and South-west Australia are often lighter 

 and more or less conspicuously banded. The scales near the caudal fin 

 are generally cycloid, but are sometimes markedly ctenoid ; those on the 

 operculum and cheek are often very rudimentary and sometimes wholly 

 wanting. A most critical comparision of these specimens fails to discover 

 any character by which they may be definitely distinguished from the 

 typical G. husseltii of tropical waters. 



Locs. — We have examined over one hundred specimens from the 

 following localities: — Port Jackson and the neighbouring coast ; including 

 the holotype of Gobius dein-essns, Ogilby. Port Phillip, Victoria ; coll. 

 C. "J. Gabriel. South Australia, various localities. South-western 

 Australia; coll. A. Abjornsseu.

D. vi/10; A. 9; P. 17; V. i/5 ; C. 15. About 31 rows of scales 

 between the axil and the hypural joint, and about 13 between the anterioj- 

 dorsal and anal rays. 



Depth before the ventrals 4-6 in the length to the hypural joint ; head 

 3"4 in the same. Eye as long as the snout, 4-4 in the head ; interorbital 

 space 2*5 in the eye. Depth of the caudal peduncle equal to half the 

 length of the head. Breadth before the pectorals I'l in the depth. 



Head depressed, broader than deep. The cheeks and opercles are 

 completely covered with large scales, vphicli are usually hidden in thick 

 mucous. The whole head bears upstanding ridges of mucigerous papilla?, 

 which are regularly arranged as illustrated in the accompanying figure. 

 Ey^s superolateral, separated by a narrow concave interorbital space. 

 Nostrils close together, tubular, the anterior overhanging the upper lip. 

 Snout depressed, the lower jaw much longer than the upper ; mouth 

 oblique, the maxilla not quite reaching the vertical of the orbital margin. 

 An outer series of enlarged conical teeth in the premaxillaries, followed 

 by a narrow band of villiform ones ; in the mandible the larger teeth are 

 present anteriorly only, and the villiform ones are somewhat larger on the 

 sides of the jaw. Tongue free and rounded anteriorly. Gill-openings 

 lateral, about as bi^oad as the isthmus separating them. Exposed edge of 

 the shoulder girdle smooth.
