returned to the cage an hour later the bat was found hanging head 
downward in a dark corner. In this position she remained for several 
days, and seemed absolutely indifferent to particles of fresh meat or 
insects held very near to her mouth. 
When placed upon a smooth rug the bat scrambled forwards using 
her folded wings with great dexterity. In this instance the terminal 
joints of the wing were tucked away close to the bat’s body, beneath 
the lateral membrane. When placed upon pebbly and twig-strewn 
ground the bat, before starting forwards, folded her slender wings 
closely and placed the delicate terminal portion upon the dorsal sur- 
face of the wing itself, in the angle between the humerus and radius, 
safe out of harm’s way. After being kept alive in captivity for 
three weeks the bat was chloroformed, as it refused to eat. The 
weight of the living bat when first received was found to be 114 ounces 
(42.5 grams). 
In the latter part of May, 1913, Mr. Camp procured three more 
living Humops from the same Sierra Madre haunt. These were kept 
alive at the Museum of Vertebrate Zoology from May 24 to June 5, 
1913, and were then chloroformed, as they unfailingly ignored all food 
offered them. Hach individual proved to be a female containing a 
single embryo. The breeding time of the species is thus indicated.
