1928. Of the 33 species known from the island the breeding 

 habits of over half are completely unknown, and the information 

 concerning most of the others is very meager. For more refined 

 work on individuals the field is almost unHmited. And nowhere 

 on, earth can such work be done so easily or under such good 

 conditions. It is with the idea of facilitating such life-history 

 work that this paper has been written. 



In the list and key which follow persons acquainted with the 

 literature may notice certain differences from records pubhshed 

 by Noble (1924, Proc. Biol. Soc. Washington 37, p. 65-72) based 

 on the collections of the National Museum. These records follow. 

 The record of Bufo valliceps from Porto Bello (based on a specimen 

 of B. coniferus); Agalychnis moreletii from Panama (based on a 

 specimen of this species collected in Guatemala by Van Patten) ; 

 Atelopus varius from Miraflores (no such specimen is in the 

 National Museum); Eleutherodactylus hrocchi from Cerro Bruja 

 (not seen, but specimens from Pirri Range labeled hrocchi are 

 what I am calling ventrimarmorata) . 



The only other recent list from the region is that of Barbour 

 (1906, Bull. Mus. Comp. Zool. 46, p. 224-229). This is for islands 

 in the Gulf of Panama, and for the savanna region near Panama 

 City. 



Mr. Arthur Loveridge has kindly looked up some of these 

 specimens for me. The following records need to be changed: 



Coecilia gracilis (p. 228), M. C. Z. no. 2502, is really Caecilia 

 ochrocephala. 



Hylodes hrocchi (p. 229) from San Miguel Island is a specimen 

 of Eleutherodactylus fitzingeri, M. C. Z. no. 8024. 



Bufo spinulosus (p. 229) is a specimen of Bufo marinus, M. C. 

 Z. no. 2438. 



Phryniscus laevis (p. 228) which was M. 0. Z. no. 2437, has 

 been 'spoiled and discarded.' In the absence of any other modern 

 specimens, this record may be questioned. 



Hyla leucophyllata (p. 229). The 'five' examples from Panama 

 cannot now be found, nor can Mr. Loveridge find any clue as to 

 their whereabouts or identity. The record may well be held in 

 abeyance for the present.
