JULIAN relates ftrange things of the affecti- 

 on this ipecies bears to its young: among 

 others, he fays, that it will permit the fmall 

 brood, when in danger, to fwim down its mouth, 

 and take fhelter in its belly. This faft has been 

 fmce confirmed by the obfervation of one of our 

 bed idthyologifts *, and is no more incredible, than 

 that the young of the OpcJJum mould feek an afy- 

 lum in the ventral pouch of its parent, a fact too 

 well known to be contefled. But this degree of 

 care is not peculiar to the blue mark, but we be- 

 lieve common to the whole genus. 



This fpecies frequents many of our coafts, but 

 particularly thofe of Cornwall during the pilchard 

 feafon, and is at that time taken with great iron 

 hooks made on purpofe. 



It is of an oblong form : the nofe extends far be- Descrip. 

 yond the mouth : it wants the orifices behind the 

 eyes, which are nfual in this genus : the nollrils 

 are long, and placely tranfverfely. Artedi remarks 

 a triangular dent in the lower part of the back.
