166 TRICHODON, &C. 



New Holland Seas, H. sexlineatus, and charac- 

 terized, like the last, by longitudinal bands of a 

 deep colour. 



Trichodon. In this place Cuvier, in his 

 Appendix, directs that Trickodon and Sillago 

 should be placed. They vary from those imme- 

 diately preceding in the dorsal fins being separated 

 from each other, as in the first division of the 

 family, and the first has a certain resemblance to 

 the genus Trachinus. The preopercle has four 

 or five very strong teeth or spines, and the opercle 

 is finished by a flat plate ; the skin is without 

 scales. One species only is known, T. SteUerii, 

 found on the coast of Kamtschatka, and parti- 

 cularly round the island of Unalaschka. It is 

 well known to the inhabitants, who take them 

 when burrowing in the sand like the Weavers. 

 The females deposit their spawn in furrows of the 

 sand, and are remarkable in being said to attend 

 the young after they have been hatched. 



Sillago is of an elongated form, the mouth 

 small, but the upper jaw rather protracted ; the 

 preopercle is toothed on its rising edge, and 

 beneath bends under, so as almost to touch that on 

 the opposite side when the animal is in a state of 

 rest ; the opercle is terminated by a single sharp 

 point. The dorsal fins are separated from each
