12 MESSRS. MURIE AND MIVART ON THE 
two smaller subequal ones (nos. 3 and 4) respectively between the roots of the third and 
fourth and the fourth and fifth pedal digits. Another, elongated but narrower, pad 
(no. 5) occupies the peroneal border of the sole. 
In Galago (woodcut, fig. 8) the pad beneath the hallux is not marked by so deep a 
furrow (if by any) asin Lemur. The other pads are similar, except that a rather shorter 
one occupies the place of that elongated pad which is placed beneath the peroneal 
border of the sole in Lemur. 
A marked difference, indeed, is presented between Lemur and Galago, in the large 
extent of hairy surface at the hinder part of the sole corresponding with the elongated 
naviculare and os calcis. 
In Microcebus myoxinus Peters’ mentions that the naked anterior sole of the foot has 
six pads, of which that between the first and second toes is found particularly large. He 
does not state, however, whether there is a tendency to division in the hallucial eminence. 
In Nycticebus tardigradus (woodcut, fig. 10) the pad beneath the hallux is marked by 
a depression which seems to correspond to the antero-posterior groove of Lemur opened 
out (nos. land 1*). The pad beneath the root of the index (no. 2) has another, smaller 
pad placed immediately behind it, while the third and fourth digits have each their 
own, very small pad placed at the root of each respectively (nos. 3and 3*). The pad at 
the root of the fifth digit (no. 4) is very imperfectly divided from the one bounding the 
peroneal side of the sole behind it (no. 5). 
In Zarsius, according to Burmeister’s description’, there are three, unequal, elliptical, 
transversely wrinkled pads, of which the largest corresponds to the ball of the great 
toe; the middle one occupies the base of the second and third digits; and the smallest 
but longest one, partly applied to the outer border of the foot, is placed opposite the 
fourth and fifth digits. 
In Chetromys the plantar surface of the foot and the pads thereon correspond almost 
identically with those of Lemur. 'The peculiar delicate tracery or papillary structure 
and the fine parallel lines upon the pads themselves, both of the hand and foot, have 
been beautifully illustrated in Peters’s monograph (op. cit. tab. i. figs, 2 and 4). 
II. Muscunar System. 
1. Muscles of the Head and Neck. 
a. Epicranial and Auricular Regions. 
OccIPIT0-FRONTALIS.—This muscle is well marked in Lemur catta, and covers each side 
of the skull, its fibres being far more strongly developed posteriorly. Its origin and 
insertion are as in Man. 
In L. varius the muscular fibres are very sparse, the entire sheet of aponeurotic and 
fibrous material being exceedingly delicate.
