The author remarks that the species provided with a pouch are exclusively 
neotropical, that the pouchless American species are more closely allied to 
those with a pouch than to those of the Old World, and that the single 
African species shows more affinity to the American forms than to Emhal- 
lonura, which is limited to the East.

'^Amhlyotus atratus. Kolenati had described a bat from Mount Altvater, Jn 
Moravia, under this name (Sitgsber. Ak. Wiss. Wien, 1858, xxix. p. 250). 
Its existence as a distinct form had been doubted ; however. Hr. Jeitteles (1. c.) 
has rediscovered it, and, after having given a detailed description, he sums up 
its characters thus (p. 9) : — Amhlyotus. Molars Ears without folds, and 
with the outer margin terminating in front of the tragus. Tragus convex on 
the upper third of the inner margin, its end being rounded and bent upwards 
and outwards. Calcaneum with an extremely narrow, lateral cutaneous flap, 
not projecting outwards. Thus the genus would be intermediate between 
Vesperugo and Vespertilio, — Char. spec. Ears much shorter than head } 
wing-membrane reaching to the root of the toes ; extremity of tail projecting 
beyond the membrane. Cutting-surface of the lower front teeth parallel to 
the direction of the mandible. The first upper front tooth bicuspid, some- 
what higher, and transversely conspicuously stronger than the second. Snout 
broad and obtuse, with but few hairs, black. Hairs on the back shining 
golden. The author adds that this bat is possibly a hybrid between Vespe- 
rugo nilssonii, or discolor, and some species of Vespertilio, perhaps dauhentonii 
or mystacinus. (A translation of this paper appeared in Ann. & Mag. Nat. 
Hist. 1868, i. pp. 157-160). 
Insectivora. 
^ Mr. St. G. Mivart has published an elaborate paper on the 
osteology of this family, dwelling principally on the structure 
of the skull and dentition. Journ. of Anat. & Physiol. 1867, 1st 
ser. pp. 281-313, and 2nd ser. i. pp. 117-154. He first describes 
six typical forms, viz. : — Rrinacms, Talpa, Sorew, Tupaia, Ma- 
croscelides, and Centetes. The other genera examined are : — Hy- 
lomys, Ptilocercus, Petrodromus, Rhynchocyon, Gymnura, Con- 
dylura, Scalops, and Scapanus (in the first part of the paper) ; 
TJrotrichm, Myogale, Ericulus, Echinops, Solenodon, Potamogale, 
Chrysochloris, Calcochloris (g. n. = Chrysochloris , spec., with two 
molars and without vesicular enlargement in the temporal fossa).
