344 University of California Publications in Zoology (Vou. 17 
sent to the Museum of Vertebrate Zoology by Mr. W. C. Hanna, 
who found it on March 13, in a cave near Whitewater, Riverside 
County. When received at the Museum the bat was cold and torpid 
and the long ears were folded backward and downward and against 
the sides of the head; the long narrow tragi, however, stood rigidly 
erect (pl. 17, fig. 12). The ears were not bent sharply back, but 
curved by a regular and even crimping of the folds along the inner 
edges of the auricles, the effect thus produced reminding one strongly 
of the curving horns of a mountain sheep (pl. 15, fig. 4). 
When the bat was taken into a warm room and handled his ears 
gradually unbent (pl. 15, fig. 5) until they stood erect and directed 
slightly forward (pl. 15, fig. 6). He soon became lively and protested 
in shrill cicada-like notes, and when released he quickly took flight. 
The aerial motions of the little mammal were fascinating to watch 
as it repeatedly circled the room in its search for an exit. At one 
moment it was drifting as easily and slowly as a butterfly on a sum- 
mer breeze, at another it was skimming as swiftly as a swallow, down 
almost to the surface of the floor, then up among the recesses of the 
beamed ceiling, an instant hovering where a draft of air came 
through the crack beside the closed door, then over to each window 
in turn, hovering up and down before the pane, touching nothing but 
the light cord which hung from the edge of each window-shade, and 
which retreated before the fanning wings. 
A wild bird loosed in a room stirs one to instant pity by its head- 
long dash against the window glass; but the wild bat aroused only 
keenest admiration, for the dexterity of his searching flight was such 
that not a hair was ruffled. 
Tired by his long flight the bat at last retreated to a beam of the 
ceiling where he hung in a shaded recess, head down, but ears and 
eyes alert. Finding himself unmolested his vigilance gradually re- 
laxed, his eyes closed, his ears curled backwards, the tip of his tail 
curled under him, his thumbs turned back under his wings, the tiny 
claws thus aiding in the supporting of his body, and he was asleep.
