POLYDACTYLUS MULTIRADIATUS (Gunther). 
Polynemua multiradiatus Gunther, Brit. Mus. Catal. Fish., ii, 1860, p. 324. 
(Plate XXI.) 
Depth of body 2*75 to 2*94, length of head 3-3 to 3*45, of caudal fin 2*6 to 2*87, 
of pectoral 3*3 to 3-46, of upper free ray 2*81 to 3-03, of ventral 5*75 to 6*1 in length of 
body. Length of snout 3-95 to 4-35, diameter of eye 3*3 to 3*5, width of interorbit 4*1 
to 4*4, length of maxillary 4*15 to 4*25, longest dorsal spine 1*5 to 1*56 in length of 
head. 
Dorsal contour of body much more elevated than the ventral, its width 2*75 to 
2*82 in its depth, which is greatest immediately in front of the anal fin and is one fifth 
more than the length of the head ; caudal peduncle two fifths longer than deep, its 
least depth 2*33 to 2*44 in the depth of the body. Head moderate, with convex 
occipital profile, its width 2 to 2*1, its depth 1*33 to 1*4 in its length. Snout with 
linear or slightly convex upper profile, its anterior border linear and strongly declivous, 
1*3 to 1*33 in the eye-diameter ; interorbital region feebly convex, its width 1*2 to 1*4 
in the same. Premaxillaries feebly emarginate ; maxillary extending to a pupil- 
diameter behind the eye, the width of its distal extremity 3*43 to 3*56 in its length 
and much more than the depth of the preorbital, tip of mandible vertically below the 
anterior border of the eye. Vertical limb of preopercle evenly and finely denticulate, 
the lowermost tooth much stronger but scarcely longer than the others. 
Scales in 7/59/12 series. Soft dorsal and anal fins with a wide basal scaly 
sheath ; a pointed scale in the axils of the pectorals and ventrals, that of the latter 
the longer and narrowly lanceolate, about as long as the eye-diameter. Lateral line 
forked on the caudal fin, a branch extending on each lobe. 
D. viii, i 14 or 15 ; A. iii 17 or 18 ; P. 15 + vii. Length of spinous dorsal 1*65 
to 1*8 in the soft and 1*5 to 1*7 in the third spine, which is 1*2 to 1*3 in the height of 
the soft dorsal, the outer border of which is deeply emarginate, the last ray being
