Note on a Shark and Ray obtained at Lhtle 



Metis, on the Lower St. Lawrence. 



By Sir William Dawson, F.R.S. 

 (With Plate IV.) 



Some of the summer resorts on the Lower St. Lawrence 

 are not destitute of supplies of fish. In addition to the 

 delicious trout of the lakes and streams, the sea affords, at 

 certain seasons, an abundant harvest of various kinds. At 

 Little Metis, for example, salmon are taken in the St. Law- 

 rence in early summer. A little later, mackerel, herring, 

 and the delicate sardine make their appearance, and floun- 

 ders, loche or tom-cod, and smelts are taken by juvenile 

 anglers. Now and then the brush wears erected on the 

 shore capture a specimen of the great Albecore or horse 

 mackerel, an excellent fish, and the striped bass is some- 

 times taken in the same way. Formerly the cod was taken 

 in considerable quantity, but it seems to have deserted the 

 locality, except that a few " rock cod " and young cod, 

 scarcely larger than the loche, are sometimes caught. Of 

 late years, however, the halibut has appeared in sufficient 

 numbers to make a profitable fishery for local use, and it is 

 in connection with the halibut fishery that the animal to 

 which this note refers has made its appearance. 



The halibut fishers, using herring or sardine for bait, oc- 

 casionally hook a large shark, and find little difficulty in 

 capturing it. Five or six specimens, some of them ten feet 

 in length, were thus taken and towed ashore last summer. 

 They are not valued for food, but the liver yields a consid-
