hanging together might be undefined? All others taken were males. On the north side of the trail from the main grove were a few banana trees along the team. I found two Uroderma there. In the main grove I saw two Artibeus hanging under a bent over banana leaf. They were too close together that their bodies touched. I shot and got one, No. 12229. This is a very peculiar form in that it has the following dental formula -3 1, - - 3 4 5 6 7 In Miller's +2-1, -2-4 5 6 7 Families and Genera of bats he speaks of only one species of Artibeus having such a formula, that being A. planirostris a much larger form. In some of the Uroderma and the one Artibeus taken the pelage had greenish olive tinge. Specimens taken today. Artibeus No. 12229; Uroderma Nos. 12224 to 12228 inclusive cloudy in afternoon. Rained a little during early evening.
