220 KECORDS OF TUB Al'SIKAMAN MUSEUM. 



Body I'obust, compressed posteriorly. It is covered with large strongly 

 ctenoid scales, which completely cover the nape, bases of the pectorals, 

 breast and abdomen ; they are largest posteriorly, and the hinder ones of 

 the median row on the caudal peduncle ai-e larger than the others. Candal 

 peduncle very broad and compressed. Genital papilla small. 



Fii*st dorsal tin originating over the anterior halt' of the pectoral; tlie 

 second to fourth rays ai-e subeqnal in length, and tlie latter reaches the 

 origin of the second dorsal when adpressed. Dorsal rays increasing 

 slightly in length to the penultimate, which is about as long as the spines. 

 Anal opposite to, and of similar form to the second dorsal, but with a 

 shorter basal length. Pectoi'als obtusely pointed, the median rays reaching 

 to tlie vertical of the anterior dorsal ray. Caudal bi-oadly rounded. 

 Venti-al tins united at their base l)y a narrow membrane ; the rays increase 

 in length to the fourth, but the tiftli is much shorter. 



Culoiir-inarL-iiiij. — Light brown in alcohol, with broad darker brown 

 cross-bands ; one of these is placed below each dorsal fin and one across 

 the caudal peduncle, and they liave numerous irregular dark markings 

 between them. The cross-bands extend onto the dorsal tins where they 

 break up into irregnlai- dai-k marblings. Pectorals, caudal, and anal with 

 irregular dark cross-bars, the base of the former with two darker stripes. 



Described and figured from a specimen -i? mm. long, from Twt) Isles, 

 North Queensland. 



Variation. — A series of over one hundred specimens 23-56 mm. long, 

 exhibits some variation in the details of the colour-marking, which is 

 much more pronounced and more variegated in some specimens than in 

 others. The mucigei-ous system of the head is as well developed in the 

 youngest as in the largest specimens, and the ridges are similarly arranged. 



This species has been associated with Gi)hioiiiorphn!t, Gill, by Jordan 

 and Seale, but it differs from that genus in the great development of the 

 cephalic mucigerous system. This character distinguishes it from all 

 other genei-a known to us except C alloy ohiuh; from the tj'pical species of 

 which it only differs in the structure of its ventral tins. In C. Iiasseltii, 

 these are truly gobiqid in form, having a distinct though narrow basal 

 membnine uniting the spines; the fifth rays are slightly .shorter than tlie 

 fourth, but are united by membi-ane to their tips : in C. srhiteri the 

 ventrals have no anterioi- basal membi-ane connecting the spines ; the inner 

 i"ays are much shorter than the others, and are connected by membrane 

 only at their extreme bases. There being no other major differences 

 between them, it seems probable they are congeneric.
