ZOOLOGICAL LITEUATUKE. 
Spot above the root of tlio tail (croupion), it may be distinguished by a 
specific name, L. mayottensis (p. 76). The author then describes the varia- 
tions of colour in ten specimens. 
The species from the south-west coast of Madagascar examined by the 
author is represented by two examples : the female agrees with L. Icucomys-’ 
tax (Bartlett); the male with Z. macaco (L.)=Z. niyer (Geofir.), which 
names must be considered synonyms of the same species (p. 77). 
Otolicnus crassicaudatiis. Dr. Sclater, after a comparison of the typical 
specimens, arrives at the same conclusion as before (Proc. Zool. Soc. 1864, 
p. 711 j Zool. Record, i. p. 15), viz. that Galago monteiri (Bartlett) is little, 
if anything, more than a pale variety of O. crassicaudatus ] and that O. cras- 
sicaudatus, var. kirhii, is intermediate between it and the type of 0 . crassi’- 
caudatus. 
\\ Nycticelus tardigradus. Messrs. Mivart and Murie have examined and 
described the muscular structure. Proc. Zool. Soc. 1865, pp. 240-256. As 
points of especial interest are pointed out — 1. The appearance of that anthro- 
poid muscle, the flexor lougus pollicis, and its resemblance, by the inter- 
lacements of its tendons with those of the flexor profundus, to the conditions 
always ofiered by the foot in Primates. 2. Tlie almost atrophied gastrocne- 
mius, but concomitantly augmented flexor longus communis, which last, 
inverting the analogy of the flexor longus pollicis, resembles a hand-flexor 
in its origin from the proximal bone of the limb. 3. The very large size of 
the rectus anticus major, and the generally extensive development of the 
muscles of the ventral surface of the spine.

vol. ii. 
Mr. Bartlett states that the Aye-Aye in the Zoological Gardens in Regent’s 
Park is fond of fresh sugar-cane, vdiich confirms him in his belief that the 
creature feeds upon the juices of trees. Ann. & Mag. Nat. Hist. 1865, xvi. 
p. 142. 
FERiE. 
ClIIROPTERA. 
Prof. Peters has communicated a s}^stematic synopsis of 
the groups and genera of Chiropteres, whieh will form the 
base of a monograph of this family, on which he is engaged at 
present: Monatsher. Akad. Wiss. Berlin, 18’65, p. 256, As 
we shall soon have occasion to record the forthcoming work, 
and as no characters are added in this synopsis, the present 
notice will suffice. 
4 Prof. Peters has examined the typical specimens of the 
Brazilian species described hy Srix : they appear to have suf- 
fered much from the way in which they have been prepared ; 
but by softening some of them in a weak solution of alum, the 
author was enabled to recognize the original form of the dis- 
torted parts. The chief results of this examination are the 
following [Ibid. pp. 568-588) : —
