Jtaly, which, he names var. meridionalis ; it is intermediate hetweeji M. 
vulgaris and M. hoccamela as regards the length of the tail, which is two- 
fifths pf that of the body in the Sardinian Weasel, two-ninths in the comnion 
species, and two-sevenths in the variety mentioned. Kendic. Accad. Sc.

\Zorilla alhinucha (Gray). Du Bocage proposes to change this name into 
Z.Jlavistriata, because his specimens have yellow markings' instead of white 
ones. Proc. Zool. Soc. 1865, p. 401. This alteration is inadmissible accord- 
ing to the rules of nomenclature. 
■d Vison lutreola. Dr. M. Schmidt has given an account of a specimen living- 
in the Frankfort Zoological Garden. Zoolog. Gart. 1865, pp. 168-175, with 
a woodcut. Hr. Claudius states that this species is not uncommon within a 
limited district in the vicinity of Lubeck. Arch. Ver. Freund. Ntrgesch.

Lutra vulgaris. Prof. Bischotf has discovered a sac-like appendage to the 
placenta, containing blood and hsematoidin. X. o. p. 213, with two plates.

Cystophora crisiata. Prof. Reinhardt (Vidensk. Meddel. naturh. Foren. 
Kjobenh. (1864) 1865, pp. 248-264, 277) has examined the milk-teet}i. 
The embryo, 2 feet long, was evidently not mature, and probably would 
not have been born before some weeks. It had been brought from Green^ 
land as a skin. ^ The milk-teeth were still covered by the gingiva 3 and 
after removal of the latter all became visible, with the exception of the 
lower incisors, which, probably originally present, were lost during the first 
preparation of the skin in Greenland. The milk-teeth; although fully de- 
veloped, are minute in size, and comparatively much smaller than those of 
other seals ; they are evidently never used, and it is not improbable that 
they never break through the gingiva. There are on each side of. the upper 
jaw two incisors, one canine, and three molars. T|ie incisors and the canine 
are below, and somewhat inwards of the corresponding permanent teeth, 
which are entirely hidden in the alveoli ; the three molars correspond to the 
■ second, third, and fourth of the five permanent molars. The first milk- 
incisor is styliform, about 1 millim. long, half as large as the second ; the 
canine tooth is *7 millims. long, one-third of which projects horizontally 
beyond the alyeolus, a peculiarity observed also by Nordmann in Haliclicerus 
grypus, but not by Steenstrup in Fhoca groenlandica, hispida, and harhata, 
who, however, seems to have examined specimens in Avhich a portion of 
these milk-teeth was apparently resorbed, so that their original position had 
become indistinct. The first milk-molar is 4 millims. long, its single root 
being 3 millims. ; the second is scarcely half as large, and has also a single 
root ; the third the largest, with two short but distinct roots. There was 
probably one incisor on each side of the lower jaw \ the lower milk-canine is 
vertically implanted in the jaw; three molars, also corresponding to the
