40 MESSRS. MURIE AND MIVART ON THE 
and from the septum between itself and the flexor carpi radialis, but it takes no origin 
from the ulna. It is inserted for more than an inch along the outer margin of the 
radius and also into the anterior surface of the radius, between the insertion of the 
supinator brevis and part of the radial origin of the flexor longus pollicis. 
In ZL. varius it is continued by strong muscular fibres as far down as the bottom of 
the shaft of the radius. Cuvier represents it as we have said, pl. 68. fig. 2, a. 
In G. allenii it is large and very strong. It arises from the inner condyle and covers 
the median nerve; insertion into the shaft of the radius, its middle third. The external 
cutaneous nerve lies between it and the supinator longus. Alike in Galago crassicau- 
datus (Pl. IV. fig. 14, P.r.t). 
In Loris gracilis Cuvier represents it very short as compared with Lemur’. Figured 
in Nycticebus, woodcut, fig. 12, Pt. 
In TZarsius* it is substantially the same as in Lemur. 
The FLEXOR CARPI RADIALIS® arises from the internal condyle by a strong tendon, and 
from the intermuscular septa. Its fibres terminate at about two-thirds down the fore- 
arm, in a tendon which is inserted in the ventral surface of the proximal end of the 
second metacarpal. 
In L. varius it is figured by Cuvier, pl. 68. fig. 2; also in Loris gracilis, pl. 67. fig. 2. 
Figured in Galago crassicaudatus (P1. II. fig. 3, and Pl. IV. fig. 14, F.c.7r). 
PALMARIS LONGUS.—This muscle is about the same size as the flexor carpi radialis. It 
arises from the internal condyle and intermuscular septa, and a tendon begins to appear 
at the surface above the middle of the forearm; but muscular fibres continue to be 
inserted into it for two-thirds of its length; passing over the annular ligament, it 
becomes continuous with the palmar fascia. 
Cuvier represents it as cut short in JZ. varius, pl. 68. fig. 2,@. Figured in Galago 
crassicaudatus (Pl. IL. fig. 8, and Pl. IV. fig. 14, Pa./). In Tarsius* it is as in L. catta. 
FLEXOR CARPI ULNARIS.—This is rather large, and arises from the internal condyle, the 
inner edge of the olecranon and the upper five-sixths of the inner or, rather, posterior 
margin of the ulna. Its tendon, which becomes visible somewhat below the middle of 
the forearm, receives fleshy fibres as low down as the wrist, and is inserted into the 
pisiform bone and‘also into the ulnar side of the proximal end of the fifth metacarpal °. 
Alike in all the genera®. Figured in Galago crassicaudatus (PI. II. fig. 8, and Pl. IV. 
fig. 14, F.c.u). 
FLEXOR SUBLIMIS DIGITORUM.—This is a small muscle, and only arises from the internal
