350 BONES OF LOPHIUS PISCATORIUS — MORROW. 
centre: at about one-third of its length from its proximal extre- 
mity, the ridge mentioned becomes reduced, and this extremity 
droops so as to form its articulation immediately beneath the 
paroccipital and against the exoccipital, thus lying nearly at 
right angles with the vertebral column. 
47. In this fish the interclavicle is not represented. 
48. The clavicle is very difficult to describe ; from the proxi- 
mal extremity of its upper limb to midway of the lower limb, 
lines drawn through the centres of these portions of the bone 
would in general terms form a right angle; they are not unlike 
the wooden knee of a ship in the curve formed by the upper and 
lower limbs, the lower half of the lower limb curving towards 
the centre of the fish. | Upon its proximal superior extremity 
the bone curves upward, and projecting above the supraclavicle, 
forms one of the spines of the head. A very long and strong 
spine rises just above the point of junction with the distal end of 
the supraclavicle. Upon the outer edge of the clavicle there is 
also a process for the attachment of the muscles, and at about 
one-third of the length (from its inferior extremity) of the lower 
limb of the clavicle, rises the ligament which serves for the at- 
tachment of the pelvic limbs. 
49, Accessary bone: at the base of the long spine at the up- 
per outer posterior edge of the clavicle, and attached to it, is the 
accessary bone (post clavicle, of some); it is thin and delicate. 
52. Scapula: close to the accessary, and upon the clavicle, 
and close to its outer edge, is the very small fenestrate scapula, 
and immediately beneath the scapula, attached to its inferior 
edge, but lying, its central limb in the centre of what may be 
called the junction of the upper and lower limbs of the clavicle, is 
the (51) coracoid, which is an irregularly oval cup-shaped bone, the 
edges of which are attached to the clavicle, and from its apex a 
thin process projects angularly towards the outer edge of the 
clavicle, to which it is attached by cartilage. 
53. The carpals, or brachials, in the Lophius, are (on each 
side) two in number, they are very long and are attached to the 
scapula, the coracoid, and to the clavicle. The upper carpal 
being about half the length of the lower, does not bear fin rays,
