REPORT ON ZOOLOGY, MDCCCXLII: 
volgensis, Eversm., as identical with V. Dauhentonii, a conclusion which 
I did not venture to mention in former reports, because, in my specimen, 
which was much injured by insects, the skin of the wing did not reach 
to the under end of the shin. The other species of Eversmann, the 
Vespertilio turcomanus, which I have not seen, Blasius describes as a 
decidedly new species, belonging to the group of Vespertilio serotinus. 
Schinz has found in Switzerland, Vespertilio discolor and Natter eri^ 
and has also discovered a new bat in the environs of Zurich, which he 
calls Vespertilio minutissimus. According to his description, the back is 
dark cotfee-brown ; the belly dark brown, almost black; ear small, heart- 
shaped, sloping at the outer margin ; tragus broad, lanceolate, with blunt 
point. Whole length 2" 8"', of which the tail occupies 1" ; the whole 
breadth only 6". (Verb, der schweiz. Gesellsch. 1841, s. 76). It is a 
pity that Schinz has not followed the plan laid down by Keyserling and 
Blasius, in the recognition of this species. 
Selys Longchamps (Faune Beige, p. 21) insists, that Vespert. ernar- 
ginatus is a peculiar species ; he wonders how it could be confounded 
with V. mystacinus ; it rather resembles, as he says, the V. Nattereri ; 
but differs from both by its woolly projecting hair, bright red on the 
back and over the interfemoral membrane, by very emarginated ears, 
thick snout, &c. Its colour is very like V. serotinus. The reporter 
would here remark, that Koch has also placed a separate species very 
like the V, mystacinus in the V. SchranMi, which agrees with that one 
jn the number of glanders, the form of the ears, and the flying mem- 
brane, but is different in colour. The hair, both on the upper and under 
surface, is double coloured, namely, — black on the inner half, and on the 
outer a glittering fulvous brown, perceptibly lighter on the abdomen. 
Is this the V. emarginatus ? Selys remarks also (p. 300), that accord- 
ing to his examination of the V. hrachyotis of Baillon, it is nothing 
more than a casual variety of V. pipistrellus with the oars destroyed. 
Cantor’s Vespertilio irretitus comes from the Chinese Island of Chusan 
(Ann. ix. p. 481) ; ears rounded, shorter than the head; tragus lanceolate ; 
muz;zle blunt, with some long hairs ; fur soft, upon the back brownish- 
grey, on the belly dust coloured ; tail slightly protruding from the inter- 
femoral membrane, the latter thinly haired beneath ; grinders 4-5 ; body 
2" I'" ; tail 1" V" ; length of ear 2^ lines ; breadth of ear 2'" ; length 
of the tragus 1'". 
J. E. Gray has wished to surprise zoologists, by the defining 
of seven new genera of Vespertilionidm (Ann. jNat. Hist, x, 
p. 257). 
It is evident, that he has paid no attention to the labours of Keyserling 
and Blasius, as they are in the German language. It is nothing to him, 
that from this neglect, exactly those characteristics are passed over, on
