munched up, moving the jaws only vertically. The eating was 

 attended with a loud and very harsh cranching of the teeth, not 

 produced by crushing the horny parts of the insect, for it was 

 equally perceptible when munching a bit of soft flesh. The jaws 

 moved rapidly, but yet the mastication was a long operation, for it 

 appeared to me to be performed almost wholly by the canines. As 

 the insect was progressively masticated, portions were allowed to 

 fall into the cheek-pouches (the one being pretty well filled before 

 the other was used), which when full hung down on each side of 

 the lower jaw to the depth of three or four lines, like distended 

 bags, displaying a warted surface. When the whole of one cock- 

 roach had been masticated, and deposited in the pouches, it would 

 take another, which was gradually disposed of in the same re- 

 ceptacles ; then, after a few moments intermission, by a contortion 

 of the jaw, aided by the motion of the muscles of the pouch, a 

 portion was returned to the mouth, and again masticated. This 

 was repeated till all was swallowed, and the pouches appeared 

 empty and contracted up out of sight. Small portions of the muscle 

 of a bird, which were presented to one, he chewed up and deposited 

 in the pouches ; but after being regurgitated, and a second time 

 m^asticated, they were expelled instead of being swallowed. The 

 process of eating seemed an awkward one ; it was a rapid succession 

 of choppings with the long canines, through which the tongue was 

 thrust about so nimbly that it appeared a wonder it was not im- 

 paled perpetually. 



" In order to rest like other Bats, they crawled upwards and 

 backwards by means of the hind feet, seeking the greatest elevation 

 they could attain which afforded a hold for the claws. They were 

 social, though both were males ; usually hanging side by side, or some- 

 times with the leg of one crossing the leg of the other, or even one 

 upon the other. Sometimes they brought their faces together, and 

 licked each other's open mouths in a singular manner ; and this 

 appeared grateful to them." 



The following note accompanied some specimens obtained by Mr. 

 Fraser in Ecuador : — " Esmeraldas, Nov. 1859. Skimming the bank 

 of the river, every now and then making a dash along, and actually 

 striking the water, catching the minute shrimps as they pass up 

 stream. He had a very offensive fishy smell."
