cularly to the lower end of the tibia. 2nd. Carpopatagial (Plate XVI. fig. 1, g) consisted 
of radiating fibres starting from the carpal spur, and passing backwards and inwards to 
be lost in the wing-membrane. 3rd. Coraco-patagial (Plate XVI. fig. 1, h ), a strong 
band starting from the tip of the coracoid process, and lost in the plagiopatagium by 
spreading along with the last. 4th. Coraconotal, deeper and further back than the 
last, arising, like the dorsi patagial of the Bats, from the integument over all the dorsal 
spines, and inserted into the coracoid process under the last; this muscle also arises 
from the fascia over the lower half of the lateral aspect of the thorax, and in it ramify 
the lateral cutaneous thoracic nerves. 5th. Transversus nucha? (Plate XVI. fig. 1, a), a 
singular muscle, which I think is the same as the muscle described under this name by 
Professor F. E. Schultze, of Rostock, joined to the zygomaticus major; it arises imme- 
diately below the occipital line from the median line of the back of the neck over the 
deep cervical muscles, passes forwards and crosses the next muscle to be inserted into 
the middle of the margin of the lower lip ; it runs transversely, lying on the splenius, 
the next muscle, the masseter, and the ramus of the mandible. 
The sixth of the cutaneous muscles is the most remarkable ; it may be named jugo- 
pollicalis (Plate XVI. fig. 1, b, c ) : it arises from the zygomatic arch by a flat wide expan- 
sion ; crossing under the transversus nuchge, it is inserted into the base of the rudimental 
pollex ; it is only fleshy for about half its course, and it runs in the propatagium. 
It is easy to see of these muscles that the last is of the same nature as the continued 
portion of the occipito-pollicalis, together with the platysma myoides superior ; as there 
is a rudimental occipital trapezius, there is no occipito-pollicalis proper ; the others, with 
the exception of the first and fifth, have their representatives among the Bats, and the 
nuchal slip of some of the Cheiroptera may be a depressed transversus nuchse. I could 
not trace any filaments of the spinal accessory into any part of this group of muscles. 
Pectoralis major is divisible into two parts; one of these arises from the upper half of 
the sternum and the inner half of the clavicle, the other from the lower half of the sternum : 
it is inserted as usual, and is a small muscle in comparison with its namesake in the Bat. 
Pectoralis minor arises from the third, fourth, and fifth rib-cartilages, crosses over the 
coracoid process to be inserted into the upper part of the greater tuberosity of the 
humerus. A distinct fourth pectoral arises from the fascia over the ensiform cartilage 
and upper fifth of the abdominal linea alba, crosses the tendon of the pectoralis minor 
to be inserted into the humerus even higher up than that muscle. 
The clavicular and acromial deltoids are united, and make one small muscle with short 
fibres, which only occupies a very small section of the outer extremity of the clavicle, 
and is inserted high up on the humerus ; the scapular deltoid lies over the infraspinatus 
exactly as in the Bats, and its insertion has the same relation to the foregoing muscle as 
in the Cheiroptera. 
Sterno-cleido-mastoideus is not separable into its components, except at its origin ; and 
its insertion is into the paroccipital and into the whole length of the supraoccipital 
transverse ridge.
