pect that the differences in the tympanum and (possibly) in the teeth 

 are due either to sex or to geography. 



Most of the adult specimens from the northern part of the range 

 fall within the range of variation discussed above. Parker (1933, p. 5), 

 however, reports that the young have quite an ontogenetic change in 

 color and pattern. He describes young individuals as having a pattern 

 similar to that of adult calcarata, but since that species lacks the 

 reticulations on the palpebral membrane it should be readily separable 

 from young H. geographica geographica. 



Boulenger included a specimen from Bahia (BM 69.11.3.25 

 [1947.2.13.6]) in the series of cotypes of appendiculata. That specimen 

 probably should be referred to II. geographica punctatissima, as it is 

 much paler than the northern form of H. geographica dorsally, and 

 the belly is uniformly, but not thickly, speckled. There is a beautiful 

 bright yellow spot on each heel. 



Remarks. — Lutz and Kloss (1952, p. 649) point out that all their 

 specimens from the upper Amazon region were taken in the daytime 

 on the forest floor, but always near still or slowly flowing water. 

 Their young specimens were the slate-blue color of early metamor- 

 phosed forms, but even at that early age they had the reticulations on 

 the palpebral membranes which are characteristic of the species.
