After a rain on the night of November 17 a calling male was 

 found with a female and a batch of 11 eggs. The eggs were be- 

 tween a leaf and the side of a rock and were stuck to both. The 

 female was still gravid, and the eggs were well developed, and 

 probably laid after the last rain (night of Nov. 13 or 14). This 

 looks like a case of male station and second mating. 



Phyllobates truncatus Cope. 



What I provisionally identify as this species is a tiny frog which 

 I have seen three times on the south side of the Island. 



Phyllobates talamancae (Cope). 

 I have seen one from Gatun in the Michigan collection. 



Phyllobates kingsburyi Boulenger. 

 I have seen two from the Rio Calobre. 



Phyllobates latinasus Cope. 

 I have seen two from the Cerro Azul. 



Phyllobates flotator Dunn. 



A very common frog from the stream banks of the Island. It 

 is diurnal and calls in the daytime. The call is a faint 'peep 

 peep.' Two were taken in amplexus 8 feet up on the bank of 

 the stream at Shannon 4, about 3 p. m. on November 14. The 

 male was calling, after a morning rain. I noticed the umbrella 

 mouth tadpoles feeding on the surface film on November 15. 

 Tadpoles were found in a puddle in a hollow rock off the Wheeler 

 trail November 30 well away from any permanent stream. A 

 male was taken carrying tadpoles on December 14, and another 

 carrying three tadpoles on July 31, at Pearson 15, 440 yards 

 away from water. They were calling July 23. I saw one out at 

 night on February 9. 



Dendrobates auratus (Girard). 



Not common, found in the higher parts of the Island. I have 

 three records. 



• Atelopus varius cruciger (Lichtenstein and Martens). 

 I have seen this from Val de Anton.
