Oblong, compressed, ventral profile regularly curved, much 
more convex than dorsal one. Height 2'/,—2*/,, head 3'/,—37/., 
eye 2'/,—2°*/,, longer than snout. Two pairs of diverging lines 
on surface of head, posterior halves of which run parallel. 
Maxillary reaches below middle of eye, about 2 in length of 
head. Oral border of maxillary without supplementary bone 
(cf. P. hoeveniz) but with a ligament instead. Origin of dorsal 
distinctly nearer to snout than to caudal, behind the origin 
of ventrals, which are shorter than eye and much nearer to 
anal than to suboperculum. Pectorals nearly as long as head 
without snout, nearly reaching to ventrals. Anal 2?/,—2'/, in 
length, its origin behind the dorsal. Caudal scaly, deeply 
incised, 37/,—3'/, in length. Scales generally with vertical lines, 
convex, hindmargin smooth. 25—-26 abdominal scutes. Silvery, 
back dark. Fins hyaline. Dorsal powdered with brown. Length 
up to 170 mm. [Not seen by us]. 
Habitat: Java (Batavia); Sumatra (Priaman, Padang); 
Singapore. — British India.

Oblong, compressed, ventral profile much more convex than 
the dorsal, strongest convexity below ventrals. Height 2'/,—2?/,, 
head 3'/,—3*/;, eye 2'/.—3, '/, longer than snout, nearly 
equalling postorbital part of the head. Ridges as on head of 
P. hoevent, but their posterior half parallel. Maxillary reaches 
below first half of eye, about 2 times in head. Oral border of 
maxillary without a supplementary bone (cf. P. hoeveniz) but 
with a ligament instead. Second supplemental bone reaching to 
hindborder of maxillary. Origin of dorsal nearer to snout than 
to caudal, about half eye length behind origin of ventrals, 
which are nearer to anal than to suboperculum. Ventrals 
shorter than eye. Pectorals as long as head without snout,
