THE LUMBO-SACBAL PLEXUS. 779 external genital organs, are represented in Solipeds by the ramifications of the lumbar nerves, which have been separately described. The terminal branches are the obturator crural, and anterior femural (or anterior crural). There is nothing to be said respecting the obturator nerve ; FiV. 358. it Ictives the pelvis by the obtura- tor foramen, as iu all the animals mentioned. The crural has been described as having four terminal branches: the internal and external musculo-cutaneous, the nerve of the triceps crureus (muscular hrancli), and the m- ternal saphenous. The two mus- culo-cutaneous branches have their analogue in the Horse, in the filament we have named the accessory branch of the internal saphenous. The nerve of tlie triceps is expended in the an- terior rectus, and the vastuo intemus and extemus. Tlie saphenous defcends between the muscles of the inner aspect of the thigh, beneath the aponeu- rosis, aud becomes superficial at a short distance from the con- dyle of the femur, giving a patellar branch that divides in the skin of the knee, and a tibial branch that is expended on the inner face of the tarsal articulations and the foot. The sacral plexus comprises the first three sacral nerves, t > which is added a luriibo-sacral branch furnished by the lumbar nerves, and a fine filament that ascends from the fourth sacral. Ten collaterals ami a ter- minal branch urise from this plexus. The collateral branches are divided into intrapelvic and extrapelvic: they are five iu each group. The first are des- tined to the muscles of the inner aspect of the pelvis, and tn those of the perineum and t e skin of this region. The second are distributed to the muscles on the outer aspect of the pelvis, and the sltin on the posterior face of the thitrh. They are : 1. Visceral branches that descend on the sides of the rectum and are lost in the hypogastric plexus; 2, Ne
