BARBADOS-ANTIGUA EXPEDITION 175 
side of the base of the canine. The mouth has a peculiar expres- 
sion owing to the wide triangular cleft in the lower lip, the sides 
of which are fleshy and bare, showing on each side six rounded 
parallel ridges giving a ctenate appearance. This structure is, 
I believe, peculiar to the genus Chilonycteris, to which this spe- 
cies appears to belong. The color is dark brown with a plumb- 
eous cast. 
We were told that attempts had been made to use the bat 
manure from this cave as a fertilizer. I imagine, however, that 
it would be hard to secure any considerable quantity as it 
would have to be scraped from the surfaces of the angular 
masses of rock which form the floor of the cave as far as we ex- 
plored it. 
Mr. Collens told us, by the way, that there was a species of 
fish-eating bat, Noctilio leptrinus on Trinidad, and showed us 
an item in the ‘‘ Journal of the Field Naturalists Club of Trini- 
dad,’’ giving a detailed account of this strange habit. Mr. Col- 
lens’ personal observations are as follows: 
‘*‘T have time after time seen them catching fish (Girardinus 
Guppyi) a minute viviparous fish called locally ‘millions,’ 
which used to exist in the shallow concrete drains in Tranquil- 
ity, Port-of-Spain. The same or a similar type is to be seen any 
evening, being especially visible on moonlight nights, skimming 
the sea surface in search of small fish anywhere about the small 
islands in the Gulf of Paria, Trinidad. They usually disappear 
to the caves which they inhabit at about half past five or day- 
break, and I have watched them time after time when out fish- 
ing at night or at early dawn.”’ 
About the only other wild mammals that we saw or heard of 
at Antigua were the mongoose and the ‘‘cane rat,’’ both of 
which are regarded as ‘‘vermin.”’ 
There is but one snake on the Island and that one would be 
very easily mistaken for an earth-worm, which it greatly resem- 
bles in form, size, and color. It is doubtless a species of Typhlops 
or ‘‘blind worm.’’ The head is not all differentiated from the 
body and is similar to the tail in form except in being somewhat 
biunt. The body is cylindical throughout with none of the ven- 
tral flattening of other snakes. It is covered with small im- 
bricating scales, those on the ventral surface not differing from
