calibre. The kidneys vary somewhat in shape ; one measures -rVths 

 of an inch in length and ^Vt^s in breadth, that on the opposite side 

 is much more spherical. The specimen is a female, and the uterine 

 cornua measure each 3^ inches in length. 



"Of the skeleton, when mounted, the whole length from the 

 nose to the end of the tail is 13 inches T^^ths ; the upper surface 

 of the cranium from the occiput to the inter-orbital space is in 

 form triangular and flat, the width at the occiput 1 inch -rVth, 

 of the inter-orbital space -rVths, the whole length of the head 2 

 inches -Vths, the mastoid processes and auditory cells of very 

 large size, the external meatus also large, oval, directed upwards 

 and backwards ; the zi/goma narrow and slender posteriorly, but 

 deep and stronger at its junction with the malar bone, which has 

 an ascending bony division between the orbits and temporal /o5S(^ ,• 

 the nasal bones narrow, convex, and of parallel diameter ; the lower 

 jaw is curved, broad and strong, the course of the incisor teeth is 

 visible, and the alveolar cavities of the molar teeth are well defined 

 externally ; the coronoid processes are wanting, apparently as if 

 broken off during the preparation of the skeleton, but have obviously 

 been of very small size ; the condyle elongated from before back- 

 wards, the plate deep, and the posterior angle of considerable length. 

 Dentition fzl : the exposed portion of the incisors measures -rVths 

 of an inch in length ; the molar teeth are all made up of three parallel 

 portions or bony lamincB, each portion invested with a thin coat of 

 enamel and closely united, the base of a molar tooth presenting six 

 lines of enamel and three cavities; the anterior third of the first 

 molar tooth on each side, above and below, is smaller than the 

 other two portions, and gives to these teeth a triangular-shaped 

 crown ; the posterior third portion of the last molar tooth on each 

 side above is nearly round, and gives an increase of surface to these 

 also ; in the molar teeth of the lower jaw the fold of enamel between 

 the first and second portions of the bony lamincB of each tooth does 

 not reach quite to the outer edge, and the two portions of bone ap- 

 pear therefore to be only partially separated. The direction of the 

 parallel lamince of all the molar teeth is not at right angles with the 

 line of the maxillary bones, but inclining obliquely from without 

 backwards. 



"The length from the atlas to the end of the tail is 11 inches 

 -rVths ; cervical vertebrcB 7, dorsal 13, lumbar 6, sacral 2, and cau- 

 dal 23. The scapulcB are small, measuring 1 inch from the exter- 

 nal angle to the articulation with the humerus, the spine is but 

 Utile elevated, the acromion ample, the clavicles perfect; length of 

 the humerus 1 inch -rvths, the bone strong and furnished with an 

 elongated crest descending from the head ; from the olecranon ro 

 the carpal articulation 1 inch -i^ths, the ulna and radius firmly an- 

 chylosed throughout the distal half of their length ; thence to the 

 end of the longest of the five toes ^Vths of an inch. The ribs 13 pairs. 

 The bones o{\\\e pelvis slender and elongated ; from the crest of the 

 ilium, which is but little produced, to the inferior edge of the 

 ischium is 1 inch Aths ; the ossa pubis, slight in structure, advan-
