REPORT ON ZOOLOGY, MDCCCXLIl : 
The tail has fourteen vertebrae, as in the variabilis, but it is (excluding 
the hair) of the length of the head, and marked in the same way as in 
the L. timidus, above black, beneath white. The ear is also, as in the 
L. timidus, of the length of the head, the slit of the ear much shorter 
than the head ; upper side brown ; head and sides of trunk, thighs, and 
after part of back, on the outside, dirty greyish-white, without rust 
colour. This new species appears principally to inhabit between 55° 
and 63° north latitude, where, in Russia, the Z, timidus is totally absent. 
Across the Baltic, towards the west, it is not observed. 
Kiister has remarked of the Hares of Spalatro (Dalmatia), that they 
are smaller than ours, with a very bright grey tinge on the loins (Isis, 
1842, p. 611). 
The dark-tailed variety of the Lepus crassicaudatus was correctly 
described by Riippell, in the Mus, Senckenb. iii. p. 137, under the name 
L. melanurus, 
Baclimann has revised his earlier Monograpli on North 
American Hares, and added four new species. 
His new work is contained in the Journ. of the Acad, of Nat. Sc. of 
Philad. viii. 1, p. 75. — a. Species in the higher latitudes, in winter 
becoming white. 1. Lepus glacialis : 2. L. campestris, Bach. : 3. L. ame- 
ricanus, Erxl. (L, virginianus, Harl.) : not found, as the author re- 
marks in his corrections, on the other side of the Rocky Mountains ; but 
confined to the north parts of the United States, Canada, and the north- 
east coast, as far as 64°. — h. With long ears and tail : all from the 
north-west coasts. L. Totvnsendii, Bach., new species, tab. 2 ; size of 
L. americanus ; ears, tail, legs, and tarsi very long ; fur above bright 
gTey, beneath white : at Columbia River. 5. L. longicaudatus, Gray : 
6. L. nigricaudatus, Benn. ; 7. L. Richardsonii, Bach., new species ; 
somewhat larger than L. sylvaticus ; ears and legs much longer and 
slenderer ; tail shorter ; upper side grisled grey, under side white : Ca- 
lifornia. Z. californicus, Gray. — c. Tarsi thinly haired, claws pro- 
jecting over the fur. 9. Z. aquaticus, Bach. : 10. Z. palustris, Bach. 
—d. Like c, but the feet thickly haired. 11. Z. sylvaticus, Bach. — 
e. Small ears ; head and tail short. 12. Z. artemisia, new species ; grey, 
on the nape and the limbs rusty red ; under side white ; tail above same 
colour with back, beneath white ; tarsi well haired ; body 12" : at Walla- 
walla. 12. Z. Bachmani, Wat., new species; like the L. palustris, but 
about Jd less ; ears longer ; feet thickly haired ; colour less yellow ; tail 
above greyish -black, beneath white ; body 10" : in the south-west parts 
of North America. 14. Z. Nuttallii, Bach. 
A new species of Burrowing Hares {Leporidce) has been discovered 
on the mountains of Cabool, Lagomys rufescens, Gray (Ann. x. p. 266).
