[Eeceived M a y 3, 1892.] The visceral anatomy of this Rodent has been described in the 'Proceedings' of this Society1 by M r . Garrod. The death of a specimen recently deposited in the Menagerie enables m e to supplement that paper by a few notes upon the brain and the musculature which were uot investigated by m y predecessor. I. MUSCULAR ANATOMY. The Pectoralis major may be said to be composed of four more or less distinct portions ; the attachments of these were at any rate separate : the first part of the complex muscle is inserted on to the deltoid ridge and is 16 m m . across at the insertion; immediately below this is a slip of the extensive Panniculus carnosus. Above this the second part of the pectoral is inserted on to the head of the humerus and for a certain distance down the shaft; the insertion is only slightly narrower than that of the first part, measuring 15 m m . ; two smaller slips are inserted just below the second part 1 "On the Visceral Anatomy of the Ground-Rat (Aulacodus swinderianus) " P.
