ZOOLOGICAL LITERATURE. 
The specimen described is from California, and differs in several points from 
II. leporinus. Monatsber. Acad. Wiss. Berl. 1864, p. 177. 
Georyckus. Dr. Gray (Proc. Zool. Soc. 1804, p, 123) proposes a further 
subdivision of this genus, and mentions one or two new species from Eastern 
tropical Africa. 
1. The name of Georychus is retained for species with three molars above 
and below j the species are G. capensis (Pall.) and G. alhifrons, sp. n. 
2. The species with four molars in each jaw are arranged according to the 
size and form of the molars : 
a. Ileliophohius (Peters ?). The author has some doubt whether the only 
species known to him — Georychus palUdus (sp. n. ?) — be not identical with 
Ileliophohius {Bathyeryus') argenteo-cinereus (Peters). 
b. CryptomySy Gray ; type G. holosericeus (Wagn.). 
c. CcetomySj Gray ] type Bathyet'gus ccecictiens (Licht.).

EDENTATA. 
\ Prof. Peters (Monatsber. Acad. Wiss. Berl. 1864) describes the following 
new species : Basypus pentadactylus from British Guiana, p. 179 j D. fenes- 
tratus from Costa Pica, p. 180. Another Mexican Armadillo is a variety of 
D. novemcinctus. 
^Basypus peba (Burm.). Prof. Peters has found that the Basypus happier i 
of Krauss is identical Avith this species, and that Krauss has described the 
true B. peha as B. longicaudatus. Monatsber. Acad. Wiss. Berl. 1864, p. 179. 
Bradypus torquatus. Prof. Peters proposes the generic name of Scceopus, 
if it should be thought necessary to separate this species from the other 
Bradypus. Monatsber. Acad. Wiss. Berl. 1864, p. 678. 
V Cholcepus hoffrnanni. Peters has examined six skeletons of this species, and 
found in all six cervical vertebrae only. There is in this family a great ten- 
dency to anchylosis of the various parts of the skeleton. Monatsber. Acad. 
Wiss. Berl. 1864, p. 678. 
PACHYDERMATA. 
Dr. Eitzinger lias written a paper in which lie gives full de- 
scriptions of the species of pigs (Setiyera) (Sitzgsher. Akad. 
Wiss. Wien, vol. 50) ; also the synonyms of the different species 
are added. No new species is described; Sus ceylonensis of 
Blyth is considered to be probably identical with Sus barbatus 
(S. Miill.) from Borneo. The author admits 9 species of Sus, 
2 of Potamochaerus, 2 of Porcula, 2 of Phacocliosi'us , 1 of Porcus 
(Babyrussa) , and 2 of Dicotyles. For Centuriosus pliciceps 
(Gray), he has invented the new name Ptychochcsrus plicifrons, 
and supposes that this pig is not from China or Japan, but from 
Abyssinia — an opinion founded on a very vague statement by 
the traveller voii Ileuglin, and already eoiitradieteil by Dr. Gray
