Head conical, thicker than the body and about one-fifth the length 
of it. Bothria inversely heart-shaped (the broader part being at the 
lower margin), deep, divided at the bottom by a narrow septum ; 
edges thick and raised. Proboscides round and club-shaped at their 
tips. Inferior extremity of body, as it were, truncate. Total length 
(in spirits) 103 lines, breadth of head 23 lines, of lower part of body 
3 lines, bothria 2 lines in length. 
In one specimen the head is much broader than the inferior extre- 
mity of the body, being about 3 lines broad, while the inferior extre- 
mity is only 2 lines and is terminated by a heart-shaped appendage 
of about 1 line long and of a light-rose colour (the male’).

tab. 2. f. 4. 
Body flat, of a light yellowish colour, thickish, elegantly and mi- 
nutely striated across and marked with slight longitudinal sulci, which 
run the whole length of the body. The head is narrower than the 
portion of the body which immediately succeeds it, is about 4 lines 
in length, longitudinally sulcated on the sides, smooth on the two 
faces, and distinctly separated from the body by a contraction 
which gives the appearance, as it were, of a shoulder to the com- 
mencement of the body. The bothria are shallow, oval-shaped and 
divided at the bottom by a septum, which, at about the half of its 
length, divides into two portions; the edges are raised and thickened. 
Proboscides short and stout; the inferior part of the body terminates 
in a blunt conical papilla. Length from 1} to 23 inches; breadth 
from 2 to 34 lines.

Tenia Bremseri, Baird, Cat. Entoz. Brit. Mus. 73, t. 2. f. 5. 
Head of a moderate size, surrounded with a double crown composed 
of upwards of twenty small hooks; neck very short. Articulations 
of body numerous, at first very small and nearly oblong, gradually 
enlarging in size as they descend, and becoming campanulate. They 
are marked with numerous fine transverse lines, which again are 
crossed by several strong longitudinal lines or grooves. The inferior 
angles of each joint are slightly prolonged into a point, and the margin 
is somewhat thickened (especially in the lower joints of body) and 
undulately waved or slightly scalloped. Orifices of ovaries irregularly 
alternate. Length of specimens about 7 inches; greatest breadth 
about 23 lines.
