Mr. Peale caught this animal in a pitfall, which he had dug for the purpose of catching a wolf. It is a female.

Barton, in his Medical and Physical Journal for 1806, p. 67, says, that, "Sorex minutissimus of Zimmerman, has been discovered in the trans-Mississippi part of the United States, in the country that is watered by the Missouri;" —had he reference to this species?

This sorex minutissimus, is probably synonymous with S. exilis, to which our specimens cannot be referred, whilst the character attributed to that species, of "tail very thick in the middle," is considered essential.
