MAMMALIA. 179 
Richardsonii, having, when its hairs are distichously arranged, a pale chocolate-brown 
colour down its middle, bounded on each side by a deeper colour, approaching to black, 
and lastly the whole tail is margined by pale brownish-gray. ‘The same colours occur on the 
under surface of the tail, but there is more of the pale-brown colour and less of the black. 
The feet are formed like those of A. Richardsonii. The thumb is smaller, but it has a 
larger nail; it has one joint and its nail is obtuse.

-The largest individual I saw was a male, which measured nearly nine inches to 
the insertion of the tail. The females were smaller than the males. 
In addition to the nine marmots described in the preceding pages from speci- 
mens either recent or prepared, and to the four of which I have given compiled 
notices, North America most probably possesses many others, among which may 
possibly be reckoned the Techallotl of FerNanpz*, which, like the Coztiocotequallin 
(referred to the A. Beecheyi) feeds on grain, and lives in burrows. The author 
has not mentioned whether either of these two animals has cheek-pouches or not. 
The European species of the genus are :— 
1. A. gosac (Polish marmot). 
2. A. MARMoTTA (marmot of the Alps). 
3. A, SPERMOPHILUS GuTTATUS (souslik or marmot of the Wolga). 
=“ Techallotl candam feré depilem gestat, ac breviorem, nec dodrantem vincit longitudine; non cicuratur, sed 
perpetuo mordet atrociter et corrodit oblata omnia ; fusco et candenti colore promiscué tingitur ; et posterioribus quoque 
innixus pedibus oblatam edit alimoniam, sed precipué maizii spicas apprehensas anterioribus ; oculi sunt magni si illos 
cum ceteris partibus conferas ; vivit in antris que unguibus facile excavat ; consternitque lana, gossipiove et quovis alio 
molli stramento, ac passeres voce imitatur.” FERNANDEZ, Quadr. Nov. H isp., p. 9.
