Specimen examined, 1: no. 100062, 1 mi. E and 6 mi. S Tacámbaro, 4,000 ft.
Remarks.—The one unsexed subadult measures 5.5 mm. from Ml to M3 inclusive, which measurement is near the minimum that Tate (1933: table 1, Sec. 5) records for this subspecies but larger than the maximum that he (loc. cit.) records for the subspecies sinaloae which occurs to the northward of Michoacán. Tate (op. cit.:141) lists two other specimens from Los Reyes. Our specimen was caught in a mouse trap set in dry grass between a sugar cane field and a patch of banana trees.
Sorex saussurei saussurei Merriam
Saussure Shrew; Spanish, Musaraña
Sorex saussurei Merriam, Proc. Biol. Soc. Washington, 7:173, September 29, 1892, type from north slope Sierra Nevada de Colima, approximately 8,000 feet, Jalisco.
Range.—In and above Quercus belt, probably throughout northeastern half of state.
Specimens examined, 14: nos. 8688, 52131-52141, 100076, 100077, distributed by localities as follows: Pátzcuaro, 1; 4 mi. S Pátzcuaro, 7,800 ft., 2; Mount Tancítaro (7,800 ft., 8; 9,500 ft., 1; 9,600 ft., 1; 10,000 ft., 1), 11.
Remarks.—Two males from Mount Tancítaro, with much worn teeth, catalogue nos. 52132 and 52138, measure, respectively, as follows: Total length, 122, 114; length of tail, 46, 43; length of hind foot, 15, 14; condylobasal length, 18.4, 18.3; palatal length, 8.0, 7.3; cranial breadth, 9.4, 9.2; least interorbital breadth, 3.7, 3.8; maxillary breadth, 5.5, 5.5; maxillary tooth-row, 6.8, 6.7. The long palate in no. 52132 and the broad brain case in both specimens appear to be only individual variations or possibly variations correlated with the advanced age of the two animals since in other features they do not differ from specimens which are smaller in these two dimensions. Jackson (1928:156) records specimens of this shrew from Mount Patambán and Nahuatzin.
