expansions, the skin smooth, or nearly smooth, above, and a 

 strong fold across the chest. 



Two specimens from Pichincha (11,000 to 12,000 feet), one 

 from the valley of Collanes (12,500 feet), one from Cotocachi 

 (13,000 feet), and two from Tortorillas, lower slopes of Chim- 

 borazo (13/200 feet). 



Besides these tliree well-characterized Hylodes there are 

 eleven very small specimens from Chillo, 9 to 15 millim. 

 long from snout to vent, too young to be properly determined. 

 Upon these Mr. Whymper observes, " This miniature species 

 was first brought to my notice by an English resident ; and he 

 assured me that the largest of the specimens represents the 

 full size of the species." This is evidently a mistake, as all 

 the specimens prove to be young. They perhaps belong to a 

 new species; but with the materials before me I Avill not 

 venture to describe it. 



35. Bafo ca/rideosticfus, Gtlir. 

 A male specimen. Nancgal, 4000 feet. 



36. Bafo marinus (L.). 



Two very young specimens, from near the bridge of ChiniI)o 

 (1000 feet). 



37. Bufo crucifei'^ Wied. 

 Two half-grown specimens, from Tanti. 



38. Nototrema marsvpiatum (Dum. & Bibr.). 



Thirty-one specimens from the neighbourhood of Machachi, 

 and eight from the neighbourhood of Hacienda of Antisana, 

 13,300 feet ; six tadpoles from Pedregal, 11,600 feet. 



Mr. Whymper informs me that the ground-colour was 

 bright green. " These frogs were in great numbers at this 

 locality (Machachi) ; and in the evening their music was so 

 loud as almost to interfere with hearing when walking out."
