The following anatomical notices were furnished by Mr. Collie:—This spermophile has an 
epiglottis ; a firm, bony clavicle; a large, simple stomach, resembling that of man in form, 
and equalling, in bulk, the whole stomach and liver, The intestinal canal is five times the 
length of the body, and it is not furnished within with valvule conniventes. 'The cecum is a 
large, curved, membranous pouch, three inches and a half long. ‘The liver is of a dark-red 
colour, and has a large lobulus spigelii, but its left lobe is small. The gall-bladder is deeply 
imbedded in the liver. Thespleen is oblong and purplish. There is no well-marked pancreas. 
The kidneys are situated close to the liver ; and there are no vestiges of capsule_renales*.

A, SPERMOPHILUS ? (Douglasii), auriculis conspicuis, corpore super anticé pruinoso linea interscapulari nigrescenti ;

cylindrica pilis albis nigro torquatis vestitd. 
Douglas’s Marmot, with cheek-pouches, conspicuous ears, upper surface of the body hoary anteriorly, with a black 
stripe betwixt the shoulders; pale-brown posteriorly, with many indistinct transverse dark marks; tail 
long, cylindrical, and clothed with hairs, which are ringed alternately with black and white, 
Through the kindness of Mr. David Douglas, I have received from the banks 
of the Columbia, a hunter’s skin of an animal, which very much resembles the 
preceding one. The skull and teeth are wanting, neither is it possible now to 
ascertain whether cheek-pouches existed or not, so that, until more perfect speci- 
mens are procured, some doubt must remain as to its place in the system. The 
* Fernandez gives the following account of the Coztiocotequallin : —*‘ Quauhtecallotl-quapachtli, aut Coztiocote- 
quallin a luteo alvi colore dictus, in duplam feré crescit magnitudinem (Sciwri Mewicani) alboque, nigro et fusco colore 
promiscué tegitur, si ventrem excipias qui pallens est, aut fulvus quemadmodum attigimus, et caudam gerit prelongam, 
pilosamque qua se interdum operit; vivit in terre foraminibus, et antris inclusus, in quibus quoque educat prolem : 
vescitur indico frumenti, quod raptum ab arvis in hyemem recondit. Versutus est velut et reliqui, nec unquam 
cicuratur, aut congenitam deponit feritatem.’
