surfaces of the legs and posterior part of belly, although brighter on 

 the webs between the toes. Ventral surface malachite gi-een, with 

 suffusion of orange on sides and on the anterior femur. Posterior 

 part of belly terre verte, the skin transparent, showing the peritoneum. 

 Mouth green inside, and bones green. Iris white or silvery; pupil 

 narrow, transversely elliptical with a triangular median lobule on its 

 upper and lower margin. 



Just after preservation, the whole series was com.pared, with the 

 following notations: Dorsum apple green, sometimes a very brilliant 

 deep emerald or olive-yeUow, or golden deep citron yellow. A very 

 bright cadmium-orange spot constantly present on posterior lower 

 half of distal part of femur. A sulphur-yellow stripe above anus. 

 A whitish patch below anus. Another sulphur-yellow stripe from 

 eye halfway to groin along granular dorsolateral ridge. Webs of toes 

 and fingers deep cadmiun orange. Throat oil green, the central skin 

 orange on the wrinkles. BeUy chrome yellow. The green flesh shows 

 through on the legs. Inside of mouth deep sea green to beryl green. 

 Tongue lighter glaucous green. Guanine spots sulphur yellow. Iris 

 french gray. 



A metamorphosing tadpole with legs, from this series, displayed 

 these tints: Dorsum bright apple green. A citron-yellow line from 

 eye to shoulder. Anterior part of head and snout lightening to nearly 

 citron yellow. Upper limbs olive-yellow. Chin verdigris green, belly 

 malachite. Upper part of femur light oil green. Hands brilliant 

 lemon yellow, feet gamboge. Apparently the intense orange color 

 does not develop at this early age. 



Variations. — This species is rather easily recognizable over the whole 

 of its very considerable range and does not appear to vary much in any 

 important characteristic. The Pernambuco frogs from Tapera and 

 Zona da Matta have longer and sharper snouts than the described 

 specimen, with the nostrils more projecting and nearer to the end of 

 the snout, while the heel on the adpressed hind limb reaches somewhat 

 beyond the tip of the snout. These differences are nob significant, 

 however, as other frogs in the Manguinhos series have equally long 

 legs and projecting nostrils and less rounded snouts. The seven ex- 

 amples from Hansa, Santa Catarina, are not unusual in any feature 

 unless it be that guanine spots are lacking in aU, while most of the 

 Manguinhos frogs show at least a few. In the frog from Bonito, 

 Pernambuco, the vomerine teeth are medially in contact; this con- 

 dition is approximated in some of the southern specimens. So promi- 

 nent is the dorsolateral glandular ridge on the front half of the body 

 that it shows up even in very old and soft specimens such as the im- 

 mature frog from "Brazil," USNM 12775. 



Remarks. — I have examined the type of H. massarti, MRHN Reg.
