Remarks. — The type is the only specimen known. It is with 
some hesitancy referred to the genus Chaperina as it differs 
somewhat from that genus in the palatal characters. It is not 
improbably a species of Sphenophryne. No specimen of that 
genus is at hand for study. 
Genus PHRYNIXALTJS Boettger 
Phrynixalus Boettger, Zool. Anz. 18 (1895) 17; Stejneger, Proc. U. S. 
Nat. Mus. 33 (1908) 573. 
No vomerine teeth; with or without a doubly arched palatal 
ridge; a smooth dermal ridge in front of Eustachian tubes and 
another denticulated one behind them; tongue large, rounded, 
free; tympanum present; fingers and toes free, with disks; no 
subarticular tubercles ; no metatarsal tubercles ; pupil horizontal. 
Remarks. — In this genus, only Phrynixalus annulatus Stejne- 
ger is known from the Philippine Islands. This differs some- 
what from the genotype, in that it lacks the doubly arched 
palatal ridge.

Description of species. — (From Stejneger.) “No vomerine 
teeth; no ridge between or behind the choanse which are large, 
but nearly concealed by the overhanging lip ; an indistinct, smooth 
dermal ridge between the eustachian tubes, and a well-marked 
denticulated one behind them; tongue large, rounded behind, 
extensively free (about one-half) behind and on sides; snout 
somewhat acuminate, projecting; nostrils much nearer tip of 
snout than eyes ; distance from tip of snout to eye greater than 
diameter of latter; interorbital space nearly twice as wide as 
upper eyelid; canthus rostralis rounded; lores concave; tym- 
panum rather distinct, its diameter about one-half that of the 
eye; fingers free, club-shaped, first very much shorter than 
second, much less widened at the tip than the others, the tips of 
which are nearly truncate; toes entirely free, the tips dilated, 
but not quite so much as the fingers; no subarticular tubercles 
and no metatarsal tubercles; outer metatarsals united; skin 
smooth above; upper eyelid granular with a larger and more 
prominent tubercle near the middle of the palpebral edge ; under- 
side smooth, except belly which is faintly areolated, and the 
preanal region, which is granular.” 
Color (in alcohol) . — “Dark brown above, with an indistinct 
pale band between the anterior half of the upper eyelids followed
