fined in a cage with a screech owl, ate a considerable portion of the bird 

 in one night. (See Proc. Ind. Ac. Sci. 1904, p. 84). 



Taken at Cascades, Cedar Grove (i mile east of Stony Spring), and 

 Mayfield's Cave. The following notes on breeding habits are perhaps 

 worthy of note. Dates of specimens taken and description of the embryos 

 they contained : March 27, 1903, five embryos, J inch long; March 28, 

 1903, fonr embryos, \ inch long; March 29, 1903, four embryos, very 

 small. A brood of five young, four females and one male, were taken 

 from an exposed nest in an orchard, April 7, 1903. They measured from 

 85 mm. to 87 mm. in lengtli, tlie tail from 35 mm. to 35.5 mm., and the 

 hind foot from 15 mm. to 15.5 mm. At tliis stage, the eyes are not open 

 and the ears are rather small and laid back in the fur. The prominence 

 of the head and feet is great, tlie skull is soft, and the tail translucent. 

 The color is slaty, sprinkled with gray and yellowish above, sides of head 

 light ochraceous, nose darker. The under parts and legs and feet, except 

 a narrow strip on the outside of the legs, are abruptly white. Tail, bi- 

 color. 



10. Peromyscus michiganensis (Aud. and Bach.). 



Common. This is the white-footed mouse of the fields, P. leucopus, 

 the one of the woods. Their ranges overlap to some extent, but in 

 general, a change from the vicinity of forests to open fields means the 

 vanishing of learopu^ and the appearance of michiganensis. I have col- 

 lected but one of the present species in a wood. It was with another, 

 presumably of the same kind, curled up in a snug little nest under a log. 

 They were found in the month of December while snow was upon the 

 ground. When their home was destroyed they ran over the snow in a 

 dazed way and one was caught in the hands. 



Several of this species were taken about the old ruins of a barn in a dry 

 pasture. Dunn's meadow, Bloomington, also Ih miles northwest. 



I do not recall having seen this species recorded from Indiana. My 

 identification has been verified by W. H. Osgood. 



11. Fiber zibethicus (Linn.). 



MUSKRAT. 



Very common. Still occurs along the Jordan River in the town and in 

 the University campus. In fall, many are found dead along the roads 

 where they have been killed by hoof or wheel. In December, 1903, two 

 were taken in a single week from a cellar which they entered through a 

 tile drain. Tiiere is also a migratory or running season in late May and 

 early June.
