24 millimeters and is doubtless an immature form of the spec- 
imen described here. The variations are obvious. Stejneger 
states that there is no supratympanic ridge. In young specimens 
in my collection the fold is very dim, but distinct in older ones; 
the “small star-shaped spots” are rarely evident on the back, 
but on breast and belly they are usually numerous, although 
frequently entirely wanting. The smallest specimen in the col- 
lection measures only 15 millimeters. 
It is not improbable that Kalophrynus stellatus and K. acuti- 
rostris are merely variations of the same species. It will be 
noted that I have described a specimen of very nearly the same 
size as the type of K. acutirostris. The limbs are distinctly 
longer than in Boettger’s species. 
Kalophrynus stellatus is common in western Mindanao, espe- 
cially in the swampy forests of the upper Agusan country. They 
are usually encountered hopping about during or after a rain; 
they are very clumsy and very easily captured. During the 
breeding season of Kaloula conjuncta at Bunawan several male 
specimens of Kalophrynus stellatus were taken clasping females 
of the other species. In spite of their being common I failed 
to discover their tadpoles. Several females in the collection, in- 
cluding the one described, are packed with eggs. The eggs are 
small, measuring about 1 millimeter in diameter. 
This species is known from Bunawan, Agusan, in Mindanao, 
and from Basilan. Three specimens were collected by myself in 
the latter island, which is the type locality. The types were 
collected by E. A. Mearns.

Description of species.— (After Boettger.) No vomerine teeth 
present, tongue almost circular, as wide as long; snout sharp, 
peak-shaped ; the outer metatarsal tubercle very indistinct; thighs 
comparatively short; the tibiotarsal articulation reaches only 
to the posterior edge of the tympanum; skin on back finely 
granulated, the granules of equal size; tympanum four-fifths of 
eye; head wider than long. 
Color_—Above grayish red with very indistinct, darker, island- 
like branched spots; head and sides of back darker, almost 
blackish, bordered above with a fine whitish longitudinal line; 
in the anal region a whitish transverse line; thighs with darker 
transverse bands; no round, dark, light-bordered inguinal spot.
