waved, owing to the points of each tooth being disposed rather obliquely. The first and fifth
are tricuspidate, two points on the outer, and one on the inner edge ; the second, third, and
fourth quinquecuspidate, two points on the outer, and three on the inner edge ; the anterior
point of the inner series of each tooth very small.
Fig. 7. The lower jaw of double its natural size. The incisors nearly horizontal, the four
middle ones very slender, laterally compressed and disposed in pairs, the lateral ones much
stronger, and each slightly removed from the centre-series ; the canines are slightly curved, the
convexity directed forward, the false molar is nearly of the same form as the canines, only
shorter, and with a heel or obtuse denticulus behind near the alveolus; the first, second, and third
true molars, quadricuspidate, two points on the outer and two on the inner edge ; the fourth, quinquecuspidate,
two points on the outer and two on the inner edge ; the fifth directly behind.
Fig. 8 . The trachea, and thoracic viscera,—a the heart, in situ ; b the right lung, consisting
of three lobes ; c the left lung, consisting of two lobes.
Fig. 9. The stomach a the cesophagus, b the duodenum, c the biliary duct.
Fig. 10. The cæcum :—It is slight, sacculated on one side, and about seven inches in length :
a the termination of the small intestines ; b the commencement of the large intestines : the total
length of the former is 14^, and o f the latter 16 inches.
Fig. 11. The spleen.
Fig. 12. A view of the anterior or convex surface of the liver. This viscus consists of three
lobes ; the right lobe, a, is entire, the middle one, b, is divided into three, and the left, c, into
four lobules—one of the latter set is bicornate.
Fig. 13. The posterior or concave surface of the liver a the g a ll bladder ; b the gall duct.
Fig. 14. The penis. It is pendent from the pubis, and supplied with an os penis ; a the
prepuce ; b the glans, covered with a delicate smooth skin ; c the orifice of the urethra ; d the
body of the penis, which is depressed, spatuliform, and with the skin forming irregular longitudinal
rugæ, each of which is beset with slender^ retroverted, horny spines.
Fig. 15. The testis ; the epididymis and vas deferens distinctly shewn, the latter proceeding
from the inferior lobule of the former.

state ; b b the ligamenta lata ; c c the ovaria—thin, and of a circular form ; d d the Fallopian
tubes ; e e the kidneys; f f the ureters; g the bladder; h the urethra; i the vagina.
Fig. 17. The uterus laid open, and the foetus and membranes of the right side exposed :—
a the inner surface of the uterus, covered with delicate spongy points or villi ; b the foetal membranes
; c the isthmus, by which the membranes of the one foetus is connected with those of the
other ; d a portion of the outer surface of the chorion. This membrane is covered externally
with minute spongy points, similar to those which exist upon the inner surface of the uterus,
and among these points occur a number of somewhat circular bodies like rudimentary
cotyledons. Several of the latter, particularly those which exist upon the isthmus c, are
distinctly cup-shaped ; e the amnion, through which, near to the umbilical cord, are seen the
rudimentary cotyledons ; ƒ the umbilical cord attached to the inferior and posterior part of the
membranes ; g the foetus.
In June 1836, when I first published at the Cape of Good Hope, a description of this little
animal, my principal reason for regarding it as distinct from Galago Senegalensis, was, all the
