AUSTRALIAX GOBIID^ McCULLOCH AXD OGILBY. 285 



Hah. — Eastern rivers of southern New South Wales. 



GohioniorpJiiis ijohioides, Cuvier & Valenciennes, has been wrongly 

 recorded from Port Jackson by Steindachner'^^, who probably had 

 specimens of the foregoing species before him. G. ijohloides is confined to 

 New Zealand rivei-s and estuaries.

Body compressed, deep or rather slender ; head small, compressed. 

 Scales large, ctenoid, about 28-35 between the base of the pectoral and 

 the hypural joint ; they extend forward to between the hinder margins of 

 the eyes, but leave the interorbital space naked, and cover the cheek and 

 operculum. Rows of minute pores extend around the eye, across the 

 cheek, behind the preoperculum, and on each side of the mandible. Mouth 

 rather small, oblique, lower jaw longest ; no barbies. A band of villiform 

 teeth in each jaw, palate toothless. Tongue broad, subtruncate or 

 rounded anteriorly, and largely fi^ee. Gill-openings separated by a i-ather 

 narrow isthmus, the membranes not united across it. Exposed edge of 

 shoulder girdle a smooth, curved ridge. Pseudobranchise present ; about 

 eleven gill-i-akers on the lower limb of the first arch, which ai'e stout and 

 longer posteriori}', becoming tubercular anteriorly. D. v-viii/10-13 ; A. 

 10-14 ; V. i/5. Caudal rounded. 



Affinities. — This genus is scarcely distinct from Hypseleotrix, Gill, 

 apparently differing principally in having the interorbital space and snout 

 naked instead of scaly. 



a. Second dorsal with 9-10 rays ; vertebx'se 24-25 Subgenus Carassiops. 



b. D. vi-vii/9-10, A. lO-U; sc. long. 27-29 compressus. 



aa. Second dorsal with 11-14 rays ; vertebra; 30-31 Subgenus ^its^rojobto. 



c. Medio-lateral series of scales without dark markings galii.
