16.3 Taylor: Philippine Amphibia 285 
Remarks. — This specimen differs from the Mindanao specimen 
by the following characters which appear very slight: Nostril 
not so near end of snout ; snout not so high, lores sloping more ; 
end of snout not so truncate ; tympanum nearer eye ; eye-to-arm 
fold more distinct ; distance of eye and nostril from mouth less ; 
tympanum somewhat smaller; the webbing of feet and toes 
agrees with that in the male described from Mindanao save that 
on one or two fingers the web reaches the disk on one side. 
That Rhacophorus rizali Boettger is a synonym of this species 
is scarcely to be doubted.^'^ A photograph of the type specimen 
in Germany is in my collection. It agrees very well with my 
Mindanao specimens. 
The two Mindanao specimens, a male and a female, were 
copulating when taken. They were found on the side of a tree 
about 3 meters from the ground, just above a small cavity filled 
with water. No eggs were found. The tv\^o forms were so 
strikingly different in coloration and size that it seemed two 
species were at hand. It is certainly a rare species in Agusan 
Valley. Although remarkably familiar with the fauna and 
flora of the forests, the natives to whom these specimens were 
shown had never seen the species. 
Polypedates macrotis (Boulenger). 
Rhacophorus macrotis Boulenger, Ann. & Mag. Nat. Hist. VI 7 
(1891) 282; VI 14 (1894) 87. 
Description of species. — (From Boulenger. ) “Vomerine teeth 
in two oblique groups on a level with the front of the choanse, 
which are very large. Head nearly as long as broad; skin ad- 
herent to the frontoparietals, which are rugose, studded with 
granules ; snout triangular, a little longer than the diameter of 
the orbit; canthus rostralis angular; loreal region concave; 
nostril near the tip of the snout; interorbital space (in the 
middle) not wider than the upper eyelid, the frontoparietal bones 
narrowing posteriorly; tympanum very distinct, as large as the 
eye. Fingers long, with a distinct rudiment of a web ; toes nearly 
entirely webbed ; disks of fingers about half the diameter of the 
eye, of toes smaller; subarticular tubercles moderate; a very 
small inner metatarsal tubercle. Tibio-tarsal articulation reach- 
ing the tip of the snout; tibia half as long as head and body. 
Skin smooth, granular on belly and under thighs.” 
Color. — “Grey-brown above, with a few small dark brown 
spots ; loreal region greyish white ; a dark brown band from the 
end of the snout through the nostril, the eye, and the tympanum to 
“ See Zool. Record, Kept. (1897) 30.
