Show 366 PROF. K. VON BARDELEBEN ON THE [Apr. 17, lower end of the radius, but also an aponeurotic expansion reaching to the first and second metacarpal bones. The extensor digitorum communis (" sublimis") arises from the humerus and goes to digits 2-5. The extensor digitorum "profundus," as I should like to call it, takes origin from the ulna and has the following insertions :- (1) Three tendons for digits 3-5 (ulnar border); (2) a tendon dividing and going to the 3rd and 2nd digits ; (3) a strong muscular belly with a very broad tendon divides into two, which end on the first metacarpal and on the Pp. 3. PARADOXURUS, sp. a. Flexores. There are two palmares longi (as in Linsang), the stronger radial one being supplied by the n. medianus, the other (ulnar) by the ulnar nerve. Two m. ulnares interni are present, both being supplied by the ulnar nerve :- (1) The uln. int. rad. (humeralis) comes from the humerus and is inserted into the top of the pisiform ; (2) the uln. int. ulnaris springs from the ulna and ends in the wrist in a fascia (hgam. carpi transversum). These muscles are supplied by the ulnar nerve. The "flexor digiti brevis superflcialis'' is present in this animal; it springs from an aponeurotic expansion on the wrist (which is connected with the Pp.) and has three bellies, two of them being inserted into the fifth digit, one into the fourth ending on phalanx I. and on the sheaths of the tendons. The tendon of this^.ror br. superfic. for the 4th digit is cleft and perforated by the corresponding tendon of the flexor sublimis. Both flexores longi, sublimis, and profundus take origin from the humerus, the radius, and the ulna; the sublimis is weak and goes to phalanx II. of digits 1-4 (!), the profundus is strong and ends on phalanx III. of digits 1-5. There are four lumbricales; tbe third is the strongest, the fourth arises from the tendon of the sublimis (4th digit). O n the radial border of the forearm runs a strong muscle from the humerus (interned condyle) to the radius and the Pp., where it ends in an aponeurotic expansion which is perforated by the art. radialis. The superficial muscles on the Pp. are connected with the tendon of the pronator radii teres. 8. Extensores. The extensor pollicis et prcepollicis longus (ext. poll. I., M a n ) present; it arises from the ulna and the radius. The supinator longus is weak. The radialis ext. long, and brev. are both present. The ulnaris ext. is extremely strong ; it takes origin from the |
