cracked and irregular roof 4 to 7 feat from a floor of loose fragments 
of rock, fhe bottom of the incline is filled with water, and the 
rumbling of a subterranean stream can bo heard. Close to the oava a 
very largo spring breaks out of the hillside. In the lower part of 
this cave, hundreds of bats were hanging to the roof and it was for 
them that X came to the cave. 
% the aid of a stick, a large number (over 100) bats were killed 
as they flew in a swarm about the cave when disturbed. On gaining 
the surface I found that my captures included 11 bats of one species 
• - J*, w; t, i 
and over 90 of another, the latter are very curious creatures being 
without a tail and having long slender heads with a tongue almost ex¬ 
actly like a woodpecker*s. fhe tongue is subcylindrical,-broadest 
laterally , with a slender tip which is armed along both 
sides by a row of spines like the tongue of a woodpecker, thus 
and the likeness is still further in the glutinous secretion covering 
the tongue which is readily extensible 
beyond 
the tip of* the nose, as 1 found by actual measurement. 
The tip of the nosebas a small, upright, leaf-like appendage. 
I cannot account for the use of this peculiar tongue except that 
the animals feed on the insects which abound in the flowers of the 
numerous species of cacti found all over the country here. 
These flowers are usually filled with stamens and leaflets about 
the bases of which various insects feed ami find shelter, and to se¬ 
cure these the tongue of this bat would be a perfect instrument. In 
the traps put out last night were secured & Eesperosgyg and 2 specs, of 
another mouse of a genus unknown to me. In the afternoon a Lepus 
insolltus and Sciurus were obtained. 
March 19, The mouse traps yielded quite a harvest last night.
