A descriptive list of the plants collected on the expedition, 

 drawn up by Dr. John Torrej, has been published in the fourth 

 volume of the America?! Journal of Science. References to this 

 standard work may be conveniently made by botanists. 



5. ZOOLOGY. 



No professed zoologist was attached to the expedition, the topic 

 being left to such casual attention as members of it might find it 

 convenient to bestow. Of the fauna of the region, it was not 

 believed that there were any of the prominent species which were 

 improperly classed in the Systema Naturae, of Linnasus. It was 

 doubtless desirable to know something more particularly of the 

 character and habitat of the American species of the reindeer {C. 

 sylvestris) and hyena, or glutton. Perhaps something new was to 

 be gleaned respecting the extent of the genera arctomys and 

 sciurus, among the smaller quadrupeds, and in the departments of 

 birds and reptilia. The mode of travel gave but little opportunity 

 of meeting the larger species in their native haunts, but it afforded 

 opportunities of examining the skins of the quadrupeds at the 

 several trading stations, and of listening to the narrations of per- 

 sons who had engaged in their capture. 



In effect, the Crustacea of the streams furnished the most con- 

 stant and affluent subject for enlarging the boundaries of species 

 and varieties. The collections in this department were referred 

 to members of the Lyceum of Natural History at New York, and 

 of the Academy of Natural Sciences at Philadelphia. The results
