One right ramus, bearing all three molars but lacking the other teeth and the tip of the coronoid process, needs close comparison only with certain of the smaller North American species of Sorex . From S. merriami of southeastern Wyoming, it differs in having a shorter, much shallower dentary, a shorter molar row, and a lower coronoid. In every particular it is identical with Sorex cinereus . Sorex cinereus from northern British Columbia and the specimen from Nuevo León differ from Sorex saussur

Fragments of three other specimens of Sorex occur in the collection. One of these is a right ramus, C. I. T. No. 3943, and is complete except for the canine. The other two bear no numbers and I have designated them "A" and "B." "A" is a left ramus with the dentary broken off anterior to the canine and bears p4 and the canine. "B" is a right ramus bearing m2 and the roots of m3 and is broken off at the middle of the alveolus of m1. Each specimen has certain peculiarities but they resemble one ano

The San Josecito collection contains 22 rami of a species of Cryptotis . Many are nearly complete although none possesses the incisor. In addition there is a rostrum that on the right side bears the last two unicuspids, P4, M1, and M2. I have compared these fossils with specimens of the following species of Cryptotis : C. mexicana , C. magna , C. nelsoni , C. thomasi , C. alticola , C. parva , C. orophila , C. pergracilis , C. guerrerensis , C. obscura , C. mera , C. soricina , C. fossor , C. go
