‘Hh’ieoral i)ortion of the snout as long as the longitudinal axis of the 
cleft of the mouth, tetrahedral, pointed. Angle of tlu^ mouth midway 
hetween the gill-opening and nostril. Teeth ^ on each side; long, lan- 
ceolate, Avith sharp lateral edges, without basal cusps. The third tooth 
on each side of the upi)er jaw is much smaller than those next to it. Gill- 
openings extremely Avidc, the Avidth of the first being rather more than 
its distance from the last. Origin of the dorsal fin at a v(‘ry short dis- 
tance from the base of the jjectorals, Avhich are talciform, the length of 
their loAver margin being one-fourth of that of the upper.” {(riinther.) 
(Storer’s figure of Lamna pimciata'’'’ (Fish. Mass. pi. 37, f. 1) repre- 
sents, so far as the position of the dorsal is com.'erned, the ju’esent 
European species, instead of the iireceding. No mention is made of the 
presence of lateral ciisjas on the teeth. The occurr<mce of a true Imnin 
on our coast does not seem, hoAvcAmr, to liaA^e been A’erified, although it 
is uot improbable.)
