The Tufted Chirus is distinguished by a sub-cartilaginous six-cleft superciliarly barbel. 

 In this respect, in the thickness of its fins and skin, as well as in its general habit, Pallas 

 thinks that this species is allied to the Blennies. The scales are small, thin, adhering firmly, 

 and are finely streaked and ciliated. The top of the head and the gill-covers are scaly, but 

 there are no scales on the fins, the caudal excepted. There are two thick porous lines above 

 the lateral line and two below. The dorsal is notched, the rays of the anterior portion being 

 simple, those of the posterior articulated. The rays of the anal are thick and scarcely forked . 

 Colour of the body brownish-olive, with transverse irregular blotches of pale green. The 

 under jaw, throat, and anterior part of the belly, are tawny-yellow. The dorsal is clouded ; 

 the pectorals have two broad brown stripes towards their bases, and the anal is marked with 

 about five wavy bands of sea-green.

{Mem. de Petersb.) 



Chirus lagocephalus and hexagrammus are not mentioned as having been taken on the 

 American coast. The latter is considered by Pallas to be the Hexagrammos asper of Steller, 

 and is said to be very frequent during the autumn, in the harbour of St. Peter and St. Paul. 

 Like the C. octogrammus, it is named Terpuclc, on account of the roughness of its scales ; and 

 in Pallas's opinion Steller confounded these two species together. In C. hexagrammus the 

 dorsal is deeply notched, and the rays of both parts, and also of the anal, are simple and 

 setaceous. Steller describes it as wanting an air-bladder, and having ten or twelve pyloric 

 caeca. The stomach, which was a sac of the size of a pigeon's egg, with the pylorus on the 

 right side, contained Nereides and roe of fishes. 



The Hexagrammos Stelleri of Tilesius is also called Terpuck at Kamtschatka, and is con- 

 sidered by its describer to be the Hexagrammos asper of Steller ; but it differs from Pallas's 

 figure of that species in having a three or five-cleft superciliary tuft, and indeed from all the 

 species of that naturalist, in the number of its rays and several other particulars. Tilesius's 

 figure was drawn from a living fish, and ought to be more correct than Pallas's, whose speci- 

 mens were dried, and who may therefore easily have overlooked the superciliary tufts. It 

 deserves to be remarked, however, that the number of rays in Tilesius's figure do not. cor- 

 respond with his own description.
