 This species was once very abundant, especially from 1814 to 1825, 

 but appears now to have become extinct in our waters. Specimens 

 are much desired by naturalists. It is probably identical with one 

 of the European species, perhaps S. pneumatophorus.

 thunnina Giinther, Cat. Fish. Brit. Mus., ii, 1860, p. 364. This species 

 has lately made its appearance on our coast in summer. We are not

 are certain to be found at no distant period.
