Those of the largest fish measured 5'4mm. in length by about 2mm. in 
depth (see fig. 45, pl. iii. B.), while those of the smallest (fig. 18, pl. ii. B.) 
measure 5mm. by about 2mm. It will be noticed that the earstones of 
the pogge are moderately large in proportion to the length of the fish. 
Those cf the smallest specimen are about the one twenty-third part of its 
entire length. 
Fam. PEDIcULATID. 
Genus Lophius. 
~ Lophius piscatorius, Linn. The Angler-fish. PI. iii. B., figs. 61 aud 62 ; 
pl. iv., fig. 31; pl. v., fig. 19. 
The earstones from a fairly large angler, 36 inches long, are represented 
by fig. 61 on pl. iii, B. They are comparatively broad, and their out- 
line is somewhat irregular; the lower margin, which has a stout rib 
extending nearly from erd to end, is obtusely geniculated, the angular 
part being nearly intermediate between the two extremities. The upper 
margin is arcuate and thin, and at the anterior end where it meets the 
lower margin it forms a blunt-pointed angle, but the posterior end is 
obliquely truncated. Numerous and somewhat obscure lines radiate from 
the middle portion of the lower rib to the edge of the upper margin, 
which may be crenulate or notched. These earstones are about 10°5mm. 
in length by about 7mm. in depth. The earstones of the smaller angler, 
the size of which has not been recorded, have the upper margin more 
regularly arcuate, while the lower want the angular outline of the larger 
otoliths. They measure about 5°5mm. by 35mm. The angler’s earstones 
are small when compared with the length of the fish, those of the large 
specimen mentioned being only a little over one-ninetieth part of the 
entire length of the fish, 
Fam, TRACHINID#. 
Genus T'rachinus. 
Trachinus vipera, Cuvier. The Lesser Weaver-fish. PI. ii, B., figs. 8 and 9. 
The earstones of the lesser weaver-fish are narrow and somewhat ovate 
in outline ; both ends are pointed. Those represented by the figures on 
pl. ii. B. have thin surfaces slightly decorticated, so that the markings 
are obscure. The larger of the two fishes represented (fig 8) measured 
127mm. long (about 5 inches), and the earstones were fully 6mm. in 
length by 25mm. in depth; the smaller fish measured 119 mm., and its 
otoliths were slightly smaller than the others. 
Trachinus draco, Linn, The Greater Weaver-fish. PI. ii. B., fig. 10. 
The specimen of Trachinus draco, from which the earstones represented 
by fig. 10 were obtained measured 11} inches in length. The earstones, 
though somewhat similar in shape to those of the lesser weaver just 
described, were considerably larger, being at least 10mm. long by fully 
4-5mm. in depth.
