ZOOLOGICAL LITERATURE. 
Lemmus norvegicm, M. Guyon has described his observations of an ex- 
ample kept for some time in captivity. Oompt. Rend, 1866, Sept, 7 (Rev. 
et Mag. Zool. 1866, pp. 426-432). 
•4 Sdurus atrodorsalis (Gray). Capt. Beavan and Prof. Peters point out that 
Sc. hypei'ythrus (Blyth) is identical with this species. Proc. Zool. Soc. 1866, 
p. 428. — Sdurus chrysonotus (Blyth). Notes on this species by Capt. Beavan. 
Ibid. p. A29.-^Sdurus 2 nceus, sp. n., Peters, ibid. p. 429, from Tennasserim. 
Arctomys et S^wrmophihis. Hr. E. Schauer has written on the species of 
these genera which occur in Poland and Galicia, Wiegm. Arch. 1866, pp. 
93-112. He gives an account of his observations on Sp>. guttatus (Temm.), 
and shows by a plan (pi. 4) the complicated structure of its subterranean 
burrow. Sp. dtillus has not been found. Neither the Marmot nor the Bobak 
(if they be two distinct species) occurs in Poland and Galicia Proper; they 
appear to be very scarce and nearly extinct in the Tatra and Carpathian 
Mountains. The Bobak is provided with cheek-pouches. 
Arctomys marmota. Prof. O. Schmidt reports that in the immediate vici- 
nity of Graz, on the Rainerkogel, about 200 feet above the Mur, an old 
Marmot-dwelling has been discovered, with the skeletons of four individuals, 
belonging to three generations. This discovery, the first and only one of the 
kind in Styria, leads directly to that diluvial period when, by the extension 
of the glaciers in the higher regions of the Alps, the Upper Alpine animals 
and the Alpine flora were driven down into the low grounds, the evidences 
of which have hitherto been detected chiefly in Switzerland. — Sitzgsber. Ak. 
Wiss. Wien, 1866, iii, March 8, pp. 266-269. (Ann. & Mag. Nat. Hist. 
1866, xvii. p. 392.) 
Hystrix. Dr. Gray lias examined the specimens of Porcupines 
"in the Collections of the Zoological Society and of the British 
/Museum (Proc. Zool. Soc. 1886, pp. 306-311). The results of 
/ his researches refer chiefly to the species formerly united in the 
I genus Acanlhion'y which is now divided into three groups : — 
I a. (EdocephaluSy with Acanthion cuvieri (Gray) = Hystrix africm australis 
■ (Ptrs.). This species cannot be externally distinguished from Hystrix cris- 
; tata. 
b. Acanthochoerus, with A, hartlettUy sp. n,, p, 310, formerly believed to be a 
I hybrid between Acanthion javanicum and Hystrix cristata ; and A. grotd^ • 
sp. n., p. 310, pi. 31, from the jungles behind Malacca (ibid, p, 417). 
c. Acanthion, with A. {Acanthion') hodgsonii, A. {Acantherium) javanicum, 
and A. {Acantherium) Jlemingii. 
The author adds the synonymy of each species, and remarks that Brethizon, 
Sphiggttrus, and Chcctomys have a well-developed clavicle. 
>Wasyprocta cristata. Messrs. Mivart and Murie have given an account of 
the anatomy of this animal, paying particular attention to the myological 
part. Proc. Zool. Soc. 1866, pp. 383-417. 
Lepus. Dr. Hilgendorf has communicated a preliminary notice on the 
distribution of the enamel on the teeth of the Leporine Rodents. Monatsber. 
Ak. Wiss. Berl. 1865, p. 673. 
Dr. Pigeaux states that the hybrids between hare and rabbit are not fertile, 
and that so-called fertile hybrids were merely a variety of the rabbit. Bull, 
Soc. Zool. d’Acclim. 1866, p. 334.
