In a course of lectures given at the Museum d’ Histoire Naturelle, and 
printed in Keviie Scientifique, 1871, i. no. 10, pp. 222-227, M. Milne-Eb- 
WARDS treats of the same subject, as well as of the characters of the Lemurs 
generally, their systematic arrangement, specific distinctions, and geogra- 
phical distribution. 
The same view is adopted by P. Gervats in a paper entitled ‘^M^moiro 
sur les formes cdr^brales propres a I’ordre des L^mures, accompagnd de re- 
marques sur la classification de ces aiiimaux.” Journal de Zoologie, i. 1872, 
pp. 6-27.

Lemur, Mr. Sclater remarks on the synonymy of some of the species, 
particularly from observations upon specimens living in theZoological Society’s 
menagerie (P. Z. S. 1871) : — 
1. Lemur macaco, which Schlegel justly distinguished from L. varius 
(Geofir.), p. 229. 
2. Lemur xanthomystax (Gray), p. 230. 
3. Lemur mongoz (Van d. Hoev.) or L. coUaris (Geoffr.) is the male, and 
L. nigrifrons (Gepffr., not F. Cuv.) or L, duhitis (F. Cuv.) the female of the 
same species, p. 231, pi. 16. 
4. Lemur brumieus (Van d. Iloev.) probably = Prosimia 7nelanoccp1iala 
(Gray), p. 231. 
6. Lemur Jlavifrons (Gray), p. 232.

Martin G has calculated the extent of the wings and weight 
of the pectoral muscles in flying Vertebrates, Arch. Neerl. iv. 
A Bat of the weight of a man would require a pair of wings 
two and a half metres long, and with a surface equal to one 
and a half square metre. — C. J. L. Krarup-Hansen enters 
into the mechanism of the flight of Bats in a pamphlet entitled

und Fledermause.^^ Copenhagen: 1869. 8vo, pp. 43, Avith
