Remarks. — The species was discovered in Luzon by F. Jagor. 
It appears to have been founded on a single specimen, and I 
believe it has not been rediscovered in the Islands. 
Genus HAZELIA novum 
Upper jaw with teeth; no vomerine teeth; head with well- 
defined bony ridges; a low supratemporal ridge; tympanum 
distinct; no ridges across palate in front of oesophagus; fingers 
unwebbed, with large disks; a distinct kink above disk, caused 
by a bone intercalated between last two phalanges; terminal 
phalanges bifurcate; body covered with spiny tubercles; toes 
partly webbed; pupil horizontal. This genus is named for my 
wife. Hazel Clark Taylor, who has assisted me greatly in making 
collections and in the preparation of this work. 
Type, Hazelia spinosa sp. nov. 
This genus combines certain characters of Philautus and Poly- 
pedates; it has the intercalated bone between the last two pha- 
langes on each digit; the vomerine teeth are wanting as in 
Philautus (rarely wanting in Polypedates) ; the terminal phalan- 
ges are bifurcate, shaped something between a Y and a T; the 
bony crests on head are not unlike those found in certain species 
of Bufo.
