_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. =Cryptotis pergracilis pergracilis= (Elliot) Short-tailed Shrew; Spanish, Musaraña Colicorta _Blarina pergracilis_ Elliot, Field Columb. Mus., publ. 71, zoöl. ser., 3:149, February, 1903, type from Ocotlan, Jalisco, México. _Cryptotis pergracilis pergracilis_, Miller, Proc. Biol. Soc. Washington, 24:223, October 31, 1911. _Range._--Probably statewide. _Specimen examined_, 1: no. 1721 B. Villa R. from Colonia Ibarra, Pátzcuaro. _Remarks._--Our one specimen, originally a mount, proves to have a crushed brain case. The specimen was saved on March 10, 1944, by P. Luna, who in March, 1943, told one of us (Hall) that many of these shrews fell into the cement fish-rearing tanks at the biological station situated at Colonia Ibarra, a suburb of Pátzcuaro, on the shore of Lake Pátzcuaro. We are indebted to Dr. H. H. T. Jackson for examining our specimen and assigning a name to it. =Balantiopteryx plicata= Peters Sac-winged Bat; Spanish, Murciélago Sacoptero; Tarascan word for bat is Huasís (Wasis) _Balantiopteryx plicata_ Peters, Monatsber. k. preuss. Akad. Wiss. Berlin, p. 476, 1867, type from Puntaarenas, Costa Rica. _Range._--Statewide. _Specimens examined_, 2: nos. 52224, 52225, from Apatzingan, 1,040 ft. _Remarks._--This bat is a cave dweller, not infrequently found roosting with other species. =Glossophaga soricina leachii= (Gray) Long-tongued Bat; Spanish, Murciélago Siricotéro _Monophyllus leachii_ Gray, Voyage of the Sulphur, Zoöl., 1:18, 1844, type from Realejo, Nicaragua. _Glossophaga soricina leachii_, Miller, Proc.
