rounded, extends slightly over halfway to anal. Ventral inserted 
entirely behind pectoral base, depressed fin falling very slightly 
short of vent or about two-thirds to anal, spine about two-thirds of 
fin. 
Color in alcohol largely snuff-brown, variegated with markings 
of deep to warm sepia. Lower surface of body paler. Head above 
marked with rather small obscure spots of sepia. Muzzle generally 
pale, with four deep sepia blotches on maxillary and about three 
on mandible each side. Nasal tentacle dark. Iris dull slaty. On 
trunk ill-defined blotch below front of spinous dorsal, another about 
midway in its length and third one below soft dorsal, though former 
two more or less reflected on fin. Spinous dorsal entirely blotched 
with sepia. Fewer, though larger sepia blotches on soft dorsal. 
Anal with three broad bands of sepia, four on caudal, five on pectoral, 
and four on ventral. Pectoral axil pale, also inside gill-opening. 
Length, 108 mm. Cebu. 
Our specimen agrees largely with Day’s*® account and figure! 
No specimen other than ours appears to have been secured since, and 
as it shows some minor variations we have given the above descrip- 
tion. Our example shows the dark bands and blotches on the 
soft vertical fins more pronounced and contrastedly wide on caudal. 
Its spots on the spinous dorsal are also quite distinct and numerous. 
PTEROIS HETERURA Bleeker. 
Head, 24 to 32; depth, 34 to 34; D. XII, I, 9, 1; A. II, 7, 1, rarely 
6; scales, 43 mostly according to pockets counted along close to lateral 
line to caudal base and 3 more on latter; 6 scales above lateral line 
to front of spinous dorsal, 11 below to spinous anal origin; snout, 
22 to 3 in head from upper jaw tip; eye, 3 to 34; maxillary, 2 to 24; 
interorbital, 5 to 6. Gill-rakers, 1v, 2+10 mu, lanceolate, longest 
equal gill-filaments or 23 in eye. Scales with 9 to 11 basal radiating 
striae, apical denticles weakly 5 to 7, circuli very fine. Color in 
alcohol largely faded dull brownish with traces of about five double 
sets of vertical slightly darker cross bands. On cheek three dark 
vertical bands from pupil. Dorsals light brownish, caudal and anals 
paler and all rayed portions finely spotted on rays with dark brown. 
Pectoral and ventral blackish, former with about eight to ten trans- 
verse pale vertical bands. Numeral blotch dusky-brown. Branchios- 
tegal region tinged dusky. Length, 73 to 148 mm. Thirteen from 
Takao. 
Bleeker’s figure does not show the very prominent cutaneous pre- 
dorsal flap, in some of our smaller examples nearly twice the eye in 
length. In our largest specimen the produced long caudal filaments 
render the tail equal to the rest of the body with the exception of
