CLASS PISCES. 243 



male; silvery points, and white black-edged lines on 

 the flanks ; the caudal long and pointed \ 



Trichonotus, Schn., 



Appears to be a mere callionymus, with a very elon- 

 gated body, whose single dorsal and anal have a cor- 

 responding length. The first two rays of the dorsal, 

 extended into long setae, represent the first dorsal of 

 the common callionymus. The branchiae, however, 

 are said to be well cleft 2 . 



Comephorus, Lacgp. 



First dorsal very low ; the muzzle oblong, broad 

 and depressed ; gills much cleft, with seven rays ; very 

 long pectorals, and, what constitutes their distinguish- 

 ing character, a total absence of ventrals. 



But one species is known, from lake Baikal, the 

 Callionymus baicalensis, Pall. Nov. Act. Petrop. I. ix. 1 ; 

 a foot long, of a soft fatty substance, from which oil 

 is obtained by compression. It is only to be had 

 when dead, after a storm. 



1 N.B. The Call, diacanthus, Carmich., Lin. Trans, xii. pi. xxvi. 

 does not appear to me to belong to this genus. The Call. Indicus, 

 Lin., is nothing more than the Platycejihalus spatula, Bl. 424. 

 Add Call, cithara, Cuv. C. jaculus, and other new Mediterranean 

 species ; and, of species foreign to Europe. The C. orienialis, Schn. 

 pi. vi. C. ocellatus, Pall. viii. pi. iv. f. 13. C. sagitta, id. ib. 

 f. 4, 5 ; and some others to be described in our Ichthyology. 

 Trichonotus setigerus, Bl., Schn. pi. xxxix.
