ALLEN: NOTES ON CHIEOPTERA. 61 



Two specimens, skinned out from alcohol, seem to be this species, and were col- 

 lected on Margarita Island, Venezuela. They have quite lost the rich gloss seen 

 in fresh skins. Of the specimens whose dimensions are given, the first and second 

 are skins kindly loaned by the U. S. National Museum, and the remainder are 

 alcoholics in the collection of the Museum of Comparative Zoology. 



Following are the measurements of a skull from Paraguay, No. 114,900, U. S.
