3942 Quadrupeds, 



Long-eared Bat. — December 21, a specimen found abroad, attached 

 to a wall. May 24, one was on flight at half past 3 o'clock in the af- 

 ternoon; its flight heavy and with labour. April 25, at half past 9 in 

 the morning, one hawking for flies in bright sunshine. On being pur- 

 sued it became confused, and was caught : in captivity it rose from 

 the ground with great facility. Extent of wings, lOj- inches; weight, 

 95 grains. 



Vespertilio emarginatus. — A specimen weighed 97 grains ; extent 

 of wing lOj- inches. 



Pipistrelle. — I find the extent of wing to vary from 7 inches to 8j, 

 and the weight from 42 grains to 55. There is also a note of one with 

 the extent of wing 7 T 3 o inches, which weighed 93 grains ; but this I 

 imagine to be a mistake. A friend observed of one to which the 

 young ones were attached, that they were separated from the teats 

 with difficulty, and that when separated, they were not again able to 

 lay hold of them : and the old one then seemed quite indifferent to 

 her young, running over them without care. 



February 10. — One of this species was seen on the wing at 1 o'clock 

 in the day, with the weather bright, appearing much at its ease. It 

 came from a cove in the sea-cliff. 



In July, twenty-eight of them were discovered, congregated toge- 

 ther in a square hole in the w T all of a mill ; they were all of one 

 species, but differing in size and colour. The smallest weighed 40 

 grains, the largest 83 ; colour of the former very dark, the fur less so 

 than the membrane; colour of the old ones much more fulvous. They 

 made a stridulous noise when irritated, or when creeping over each 

 other; the sound being uttered with a jerk, with the mouth thrown 

 widely open. When left at rest they huddled together. One of the 

 smaller ones held on by the teats of the dam until she escaped from 

 its hold. 



August 30, at half-past 5 o'clock, the sky clear, with a bright sun, 

 a bat, probably of this species, mounted high in the air in pursuit of 

 food ; and whilst engaged in this occupation it was seen by a swallow, 

 which immediately gave chase to it. The swallow persecuted this lit- 

 tle animal by repeatedly striking at it, and followed it closely, until at 

 last the bat was compelled to descend for shelter near to the houses. 

 But when the persecutor appeared to have withdrawn, the bat boldly 

 mounted again to the upper region of air; there, however, it was soon 

 discovered by the swallows, two or three of which now joined in the 

 persecution, and ultimately forced it again to descend to a place of 

 safety. For the third time it mounted aloft, and there turned and
