Remarks.—This species is differentiated from other Phil- 
ippine species of Rana by the very much-flattened head, the 
very large tympanum, and the presence of the two transverse 
glandular folds, or tubercles, below the anus. Specimens were 
discovered seated on the leaves of Pandanus trees which extended 
over a pool of water in an old stream bed. Two other specimens 
observed, one in the forest, the other in the same locality, es- 
caped, The species is named for my esteemed friend Elmer 
D. Merrill, director and botanist of the Bureau of Science, 
Manila. 
Rana everetti Boulenger. 
Rana everetti BOULENGER, Cat. Batr. Sal. Brit. Mus. ed. 2 (1882) 72,

A large specimen of this rare species was taken at Pasananka, 
near Zamboanga. It was found in a rain pool near the small 
park and water reservoir. The specimen agrees in detail with 
Boulenger’s admirable figure and description. The dorsolateral 
glandular fold is dim, but it can be traced for two-thirds the 
length of the body. While not mentioned in the description, 
Boulenger’s figure shows a tubercle between the shoulders 
slightly to the right of the median line. My specimen has 
a well-developed, conspicuous tubercle in the same place. The 
specimen is probably a female and consequently without vocal 
sacs.
