scattered on the cbeek ; numerous upraised rows of papillae are arranged 

 regularly on all surfaces of the head, and along the middle of the sides. 

 Snout obtuse, mandible projecting. Mouth oblique ; no barbies. Several 

 rows of small, subequal teeth in each jaw anteriorly ; palate toothless. 

 Tongue rounded and free anteriorly, slightly emargiuate on the median 

 line. Gill-openings lateral, separated by a broad isthmus; exposed 

 edge of shoulder-girdle smooth. Pseudobranchiae present ; gill-rakers 

 of first arch short, thick, and few in number. First dorsal rounded, 

 with six spines; second dorsal with ten to eleven rays. Anal similar to 

 the second dorsal. Pectoral large, rounded. Ventrals i/5, either com- 

 pletely united or with only a narrow membrane connecting the bases of 

 the inner rays ; anterior interspinous membrane present or absent.

Identity. — Bleeker's description of the species appears to have been 

 incomplete, so we rely upon Weber's notes and figure for the identification 

 of our specimens as C. hasseltii. They agree with his illustration in all 

 details, and exhibit the same variation in their colour-marking as noted 

 by him. 



We are unable to detect any differences between specimens from 

 tropical waters (G. hasseltii) and many others from southern Australian 

 coasts (G. mucosas) by which they may be definitely distinguished as two 

 species. Northern examples are usually more conspicuously marked than 

 those from the south, and generally have more of the posterior scales 

 ctenoid. But both characters are variable, and overlap in examples from 

 intermediate localities, so we recognise the southern specimens as a variety 

 of G. hasseltii only. ^
