80 years ago can be matched spot for spot with recent specimens 

 from the same trail. 



We have then in Costa Rica and Panama the species Atelopus 

 varius, smooth, with slim form, fully webbed toes. It is divided 

 into the following races: 



Atelopus varius varius (Lichtenstein and Martens) from upper 

 Costa Rica and into Panama. It is small and heavily spotted 

 above with irregular red and yellow marks. 



Atelopus varius maculatus (Lichtenstein and Martens) from 

 high western Panama. This is large and sparsely spotted with 

 rounded yellow spots. 



Atelopus varius cruciger (Lichtenstein and Martens) from 

 mountains near Panama City to the west. This race is large 

 with the black much reduced or entirely gone, or occasionally 

 persisting as an X-mark on head. 



Atelopus varius glyphus Dimn from the mountains of Darien. 

 It is brown marked with lighter, the brown predominating, and 

 sometimes uniform; a large race. 



Atelopus varius cerius Barbour from the mountains of Gara- 

 chine peninsula. A small race with dark predominating in 

 close-set, rounded spots. The light markings are red in life. 



I might add that Noble (Proc. Biol. Soc. Washington 37, p. 66, 

 1924) has stated that the National Museum possesses Atelopus 

 varius from Miraflores, but no such specimens are now in the 

 collection, nor anything from Miraflores which could possibly 

 be confused with Atelopus. Also there is no record in Washington 

 of any such specimens having been there. Noble says they were 

 collected by Goldman. Error has certainly crept in here. 



I might also add that the types of Giinther's Phryniscus 

 laevis 1858 (Cat. Batr. Grad. Brit. Mus., p. 43, pi. 3, fig. 1) were 

 said to come from Panama (two), Quito, and Chile. I have 

 seen no modern Panamanian specimens. I am inclined to think 

 that Phirix pachydermus Schmidt 1858 (loc. cit., p. 256, pi. 3, 

 fig. 26) from near Bonaventura, 5,000 feet, is the same and 

 antedates it.
