its flight, and immediately shuffle round in order to assume the in- 
verted position, as is the usual custom of our British vespertilionid 
species. The difficulty I at first experienced in getting the Bat to eat 
was overcome by smearing the expressed juices of a mealworm upon 
its nose ; thereafter it ate eight or nine of these insects each evening. 
It persistently refused to eat some cockroaches which I put in the 
cage with it, and indeed seemed to be afraid of them, starting back 
nervously when it encountered one in its rambles on the cage-floor. 
After some coaxing I induced it to seize a cockroach as I held it in 
my hand, and it consumed it entirely, but would not take another. Ii 
permitted to do so, it always ate on the wing, rising with ease from 
the table on which I fed it. I never saw the Bat use the interfemoral 
membrane as a pouch to assist it in adjusting its grip on its prey; it 
seemed quite capable of overcoming the struggles of the mealworms, 
and a cockroach is always a spiritless, submissive creature when 
seized by a Bat. On two occasions, it is true, particularly vigorous 
mealworms were thrust for a moment beneath the Bat’s belly, 
although not right into the interfemoral, and I have little doubt that 
if occasion required the membrane would function as a pouch, as it 
does in other species. House-flies were adroitly picked off the ceiling 
and consumed as the Bat flew about the room.— CHARLES OLDHAM

Notes on the Tuco-Tuco and the Hairy Armadillo.—tThe congre- 
gations of mounds of sand seen by Mr. L. HE. Adams, and the sounds 
which he renders ‘“‘Touc-Touc” (ante, p. 342), are made by some 
small rodents called Tuco-Tucos (Ctenomys), which live in colonies. 
The collections of mounds and burrows are called ‘tuco-tuconales,”’ 
and it is necessary to ride carefully and slowly over them, the ground 
often giving way under your horse’s feet. They are also very laborious 
to walk over, being sometimes extensive and very soft. Indeed, 
“tuco-tuconales” are among the things which you have to keep a 
sharp look-out for when galloping over the “camp,” and soon in- 
stinctively dislike. Few people have seen a Tuco-Tuco alive and above 
ground of its own accord, and they seem rarely to come to the sur- 
face ; perhaps they may do so at night. I obtained the remains of two 
species in Uruguay, viz. C. brasiliensis and C. magellanicus. The com- 
paratively educated man who told Mr. Adams that the ‘‘ Touc-Touc” 
was the same as the “Peludo” was, it is almost unnecessary to say, 
wrong—vyery wrong. Peludo is the name always used in the Uruguay 
camp for the Hairy Armadillo (Dasypus sexcinctus) ; it is a slightly 
different species to that found about Buenos Ayres (D. villosus), to
