REPORT ON ZOOLOGY, MDCCCXLII : 
Blasius, in his remarks on the European Marmots (Verb, der 19ten 
Versamml. d. Naturf. Braunschw. p. 87), laments that the knowledge of 
the species is not altogether clear. Sp. guttatus, the least diffused 
species, was found by him in the regions of the upper and middle 
Donetz. Nearly allied to it, he describes the Sp.- musicus, of the high- 
est Alps of the Caucausus. Sp. citillus appears to be diffused from the 
Danube and Schlesia as far as the Altai. 
Arctomys Jlaviventer has been brought by Douglas, from the moun- 
tains between Texas and California; and is described by Bachmann 
under this name (Journal of Philadelph. viii. 2, p, 309). It is nearly 
allied to the A. empetra, but the feet are brownish-yellow instead of 
black; abdomen yellow instead of rich rust red; hair of the back yel- 
lowish-white and black-coloured instead of rust brown, black and white ; 
claws half as long ; body 16" ; tail, with hair, 6" 10'"^ Bachmann men- 
tions of A.monacc (Journ. Phil. p. 322), that rudimentary cheek-pouches, 
into which a pea could be inserted, are present. 
Myoxina. — E iippell has described a new species as Myomis 
cineraceus, in the Mus. Senck. iii. p. 136. 
Tail bushy, as in the M. glis; upper surface and tail mouse-grey, with 
a tinge of a light tawny colour ; under surface yellowish-bright grey ; 
throat and paws milk white ; body 4^" ; tail 2" 5'" : From Port Natal 
in South Africa. 
A remarkable link has been found between the Sciuridce and the 
Myoxidce in the Anomalurus Fraseri.- Fraser discovered this Rodent 
at Fernando Po, and Waterhouse gave it the above name in the Ann. x. 
p. 201. The external appearance is that of a Pteromys; fur very deli- 
cate and soft, and of a sooty colour on the upper parts of the body, 
freckled with yellow ; beneath whitish ; on the under side of the basal 
third of the tail, there is found a doubled longitudinal series of large 
horny scales, with projecting angles, which assist the animals in climb- 
ing ; skull in general like that of the Squirrels, but without the post- 
orbital process, and with a comparatively large ant-orbital opening; 
molars the palate contracted between them. This genus I rank 
provisionally with the Myoxidoe, or Dormice. 
Dipoda. — To Scirtetes a species has been added by J. E. 
Gray. (Ann. x. p. 262.) 
He calls it Alactaga indica, and says that it agrees with Sc. acontium 
in the proportion and length of the hind feet, but differs from it in this, 
that it is yellowish, and that the hairs of the tuft of the tail are yellow 
with black tips ; whilst in the Sc. acontium the black hairs are one 
colour to the base, and there is only a slight indication of the peculiar
