Agalychnis calcarifer Boulenger. 



A single specimen of this most beautifully colored of all frogs 

 was taken the night of December 18 near the Van Tyne tree. It 

 is the third known specimen, the two others having come from 

 Ecuador and from Colombia. 



Agalychnis spurrelli Boulenger. 



This large species has been taken twice on the Island, the 

 night of November 15 near the Laboratory, and the night of 

 July 22 near Drayton 15. 



Centrolene pulveratum (Peters). 



Two calling males were caught near the Laboratory on a bush 

 above a stream on the night of November 20. The note was 

 'tsee.' The male has a green vocal sac. 



Centrolene prosoblepon (Boettger). 

 The University of Michigan has two from the island. 



Centrolene fleischmanni (Boettger). 



This species is quite common on the Island. The breeding 

 habits of this species have been described by Noble under the 

 name of Centrolenella parabamhae (1923, Amer. Mus. Nov. 165, 

 p. 13) from notes by Breder. I can confirm his remarks. The 

 note I cannot distinguish from that of pulveratum. The eggs are 

 laid on the under sides of leaves above streams. My first were 

 November 21, twenty feet up on a palm leaf. On the next pinnate 

 piece of the leaf a male was calHng. On another pinnate piece 

 was a later batch of eggs. The chances are these two batches 

 were laid the nights of November 19, and 20 respectively. This 

 looks like a case of a male taking a calling station and mating 

 two successive nights and calling for a third mate. They were 

 noticed calling on November 26. 



On July 18 they were calling and eggs were noted in the stream 

 valleys on both sides of the laboratory both high up in palms and 

 low down in bushes. Again I noticed two batches of eggs in 

 different stages associated with a single calling male. Calling 

 males might be with or without eggs. I got eggs again on July 

 21, and they were calling on July 23.
