be made out. Cope says that the finger disks equals 34 the 

 tympanum, and that finger I equals finger II. In my specimens 

 the finger disks equals the tympanum, and finger I is much 

 shorter than finger II. But the coloration of mine agrees very 

 well with Cope's description, and nothing else from Panama 

 does, and no other name at all fits them. I feel rather that I 

 have seen only young specimens, and with both this and lugubris 

 I am not certain as to their allocation in Phyllobates. The two 

 are very much alike. Perhaps adults would have maxillary 

 teeth, as my specimens of beatriciae-lugubris unquestionably do. 

 Also, as I hope to make clear, they fit into no known Dendrobates 

 species from the region. I am simply doing what I can with the 

 material seen. 



Note on Hylozalus and Dendrobates from Nicaragua and 



. Panama. 



One species of what might be called webbed-toed Phyllobates 

 has been seen from the region (U. S. N. M. no. 50227, 66319-20 

 from Cana, Panama). Of the five species whose descriptions I 

 know from Ecuador, Colombia, and Venezuela it agrees well 

 enough with the very brief account of Hyloxalus fidiginosus 

 Espada (1870, Jour. Soc. Lisboa 3, p. 59, San Jose de Moti, 

 Ecuador). The five species have been described on a minimum 

 of material, and I do not wish to add a name. In Dendrobates 

 three forms are known to me from the region: a rather large 

 species, black, spotted with green, usually called tinctorius, and 

 quite widespread; a small red, black-spotted form, usually 

 called typographus, from Nicaragua to western Panama; and a 

 rather large, uniform red beast, from high altitudes in western 

 Panama for which the name speciosus Schmidt 1858 (type, 

 Ivrakau no. 1017) is applicable. The typographus form is Ke- 

 ferstein 1867, and is definitely preoccupied by pumilio Schmidt 

 1858 (type Krakau no. 1018). True tinctorius has dorso-lateral 

 light lines, and the Central American form had best be known 

 as Dendrobates auratus Girard (1854, Proc. Acad. Nat. Sci. 

 Philadelphia 7, p. 226; type not in existence, from Taboga 

 Island, Panama). 



To auratus belongs maculatus Peters (1873, MB Ak. Berlin, p. 

 617) from Chiriqui, and amoenus Werner (1901, Verh. Ges. 

 Wien 51 from Costa Rica; type Vienna 1904, 3, p. 95). Possibly
