MAMMALIA.

Insectivora. 
Prof. Peters proposes, in his memoir on Solenodon (Abhandli 
Akad. Wiss. Berl. 1864), the following arrangement of this 
family : — 
A. Intestinal tract with a large ceecum. 
a. Bones of lower leg separate ; zygomatic arch complete. 
a. Ulna imperfect. 
I. Gaeeopitheci {Galeopitlicms), 
(3. Ulna perfect. 
II. Tupay^ (CladohateSf PtilocercuSf Ihjlogalc). 
b. Bones of lower leg coalesced ; zj^gomatic arch complete. 
III. Macroscelides {Wiynchocijon^ MacrosceUs). 
B. Intestinal tract simple, without caecum. 
a. Bones of lower leg separate ; no zygomatic arch j bullae osseae none, 
os tympanicum ring-shaped. 
IV. Centetina (Solemdon, Centetes^ ?JEriciduSj ?Pchinogale). 
b. Bones of lower leg coalesced ; zygomatic arch complete j bullae 
osseae more or less developed ; cranium completely ossified. 
a. Ears w’ell developed. 
V. Erinacei {JErmaceus, Gymnurd). 
(3. Ears rudimentary or absent. 
VI. Talpina (3Iyoyale, U7'otrichus,Condyhira, Scalops, Talpa,Chrysochloris). 
c. Bones of lower leg coalesced ; no zygomatic arch ; parts of the base 
of the skull membranaceous; os tympanicum ring-shaped. 
VII. SoRiCES {Sorcx). 
\Solenodon. Prof. Peters has received a specimen of this very 
rare mammal through Prof Poey, who discovered it in Cuba ; 
it proved to be a species distinct from the Solenodon of San Do- 
mingo ; the diagnoses of the two species are — ' 
1. S. paradoxus. S. supra fuscus vel nigro-fuscus, lateribus, gastraeo 
pedibusque ochraceis ; pilis incumbentibus. — From S. Domingo. 
2. S. cuhanus. S. capite, collo, pectore, gastraei lateribus fulvis vel dilute 
ochraceis ; corpore reliquo, stria longitudinali nuchm abdominisque fuscis vel 
nigro-fuscis ; pilis longissimis villosis. — From the mountains of Bayamo and 
Trinidad (western and southern parts of Cuba). 
fhe two species differ also in the form of different parts of the skull and of 
the dentition, although the formula of teeth is the same for both, at 
least in the adult state : y ; ^ ^ ; yj y^=40. Prof. Peters gives 
a minute description of the external characters, of the teeth, and of the 
anatomy, comparing them in this and in allied genera ; he is inclined to group 
it with Madagascar genera like Centetes. This memoir is illustrated by three 
plates. Abhandl. Akad. Wiss. Berl. (1863) 1864. 
Th'otrichus. Mr. Lord describes the habits of this singular animal, which 
he found on the western slope of the Cascade Mountains in North-west 
America. The specimens collected by him would belong to Urotrichus gibsii 
(Baird), but he could not find the slightest difference between this species 
and the Japanese U. talpoides. Broc. Zool. Soc. 1864, p. 161.
