Color description from life (May 23, 1924) ■ — On^ tadpole very large, 

 brownish olive mummy brown or brownish ohve. In general, dorsum 

 very dark. A few large widely scattered black spots on the dorsum. 

 The brownish olive on rear sides surrounds lemur yellow or greenish 

 yellow spots, this yellowish color on either side of belly with a few 

 small dark flecks. Middle of belly pale grayish vinaceous or vina- 

 ceous buff. Ventral pectoral and branchial region grayish violaceous 

 blue or the body color with vinaceous buff and greenish yellow spots. 



Tail. — In general a grayish color. Along the middle of the upper 

 crest is row of large spots or these connected. This a much broader 

 and more conspicuous row than in R. grylio, being about 2 inches long. 

 In middle of musculature is a dark line or area to tip of tail paralleling 

 the upper tail crest line of black. The upper tail crest is irregularly 

 black-margined to tail tip. This black more or less outlines pale 

 chalcedony yellow spots. The musculature has numerous pale gray- 

 ish vinaceous or vinaceous buff spots. Lower tail crest narrow, with 

 irregular black margin in tip region for 1 to 1^ inches, this crest 

 with numerous pale chalcedony yellow or vinaceous buff spots. Iris 

 largely black with ochraceous salmon or greenish yellow flecks.
