Drummond’s echiodon. 
flentatum is described as having in each jaw “deux dents en 
crochets,” but no further details are given: in this only 
character, however, he judges that the 0. dentatum differs 
from the present species, which had four large hooked teeth 
in the upper, and two in the under jaw. This specimen was 
found dead on the beach at Carnlough, in the county of 
Antrim, by Dr. Drummond, in the month of June — thrown 
on shore probably by a strong easterly wind. 
The length of this example was eleven inches; and the 
greatest depth, which was at one inch and four lines from 
the snout, was six lines, behind which it became gradually 
narrower and thinner to the tail. The head was one inch 
and two lines long — the profile sloping forward equally on both 
sides to the snout, which is truncated and projects beyond 
the lower jaw, and is narrow; compressed at the sides, and 
rather flat above from the eyes backward; from the eyes 
forward a central bony ridge; a few large punctures extend 
from the snout below the eye, and are continued just behind 
it; a series of small ones closely arranged extend from the 
upper portion of the eye in a curved form posteriorly to near 
the edge of the preopercle, and thence in a double row 
extends downwards. Nostrils very large, oval, transverse, a 
little in advance of the eye. Eye large, occupying the entire 
upper half of the depth of the head; wider than high, its 
distance from the snout equal to its diameter; operculum 
terminating above in a minute point directed backward, and 
strongly radiated. Mouth cleft a little obliquely. Two large 
strong teeth placed close together, and curving inwards at 
each side of the extremity of the upper jaw, the two inmost 
a little separate. In the lower jaw one slender rounded tooth 
on each side, curving outward at the base and inward at the 
point. The upper and lower jaw, and vomer, thickly covered 
with small bluntish teeth; a series of such teeth on the bones 
of the palate; those of the upper jaw exposed to view when 
the mouth is closed. On the dorsal ridge is a short stout 
spine, the point of which alone is uncovered with the skin. 
Lateral line scarcely perceptible. Vent one inch and three 
lines from the end of the lower jaw. The dorsal fin begins 
at one inch and six lines from the snout; low at first, but 
becoming wider as it draws near the caudal fin, which it
