JULIAN relates ftrange things of the afFedli- 

 on this fpecies 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 fad has been 

 fince confirmed by the obfervation of one of our 

 beft idthyologifts *, and is no more incredible, than 

 that the young of the OpoJJum fhould feek an afy- 

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

 well known to be contefted. But this degree of 

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

 lieve comm.on to the whole genus. 



This fpecies frequents many of our coafls, 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 ufual in this genus: the noflrils 

 are long, and placely tranfverfely. Ariedi remarks 

 a triangular dent in the lower part of the back,
