NEW PHILIPPINE FISHES FOWLER 111 



notch or groove posteriorly and along upper postocular. Gill rakers 

 short, strong points. Gill opening large, extends well forward or 

 opposite middle of snout. Pair of broad, triangular rostral spines. 

 Humeral spine well developed, others small or obsolete. Scales very 

 firmly adherent, regular. Kow of strong spiny bucklers along bases 

 of dorsals, those of first dorsal flat, asperous, their hind edges den- 

 tate, which gives place to a large single spine along base of second 

 dorsal. Scales of lateral line anteriorly deep, narrowly imbricated 

 and much deeper than posterior scales. First dorsal half length of 

 second. Anal opposite second dorsal and similar. Caudal moder- 

 ate, truncate. Pectoral short, reaches front of anal. Ventral little 

 shorter than pectoral. 



In this genus, which I separate from Leindotr'igla^ the anterior 

 bucklers along the base of the first dorsal are flattened and their 

 hind edges dentate. In LejiidotngJa these bucklers all form a keel, 

 like those along the l)ase of the second dorsal, each bearing a single 

 large spine. LepidotrlgU also differs further in that the broad 

 rostral spines are more or less spinigerous, entire in PachytrigJa.

PACHYTRIGLA MARISINENSIS, new species 



Figure 53 



Depth 4 m length from snout tip ; head SVs, width 1%. Snout 2yio 

 in head, eye 4, 2 in snout, IVio in interorbital ; maxillary reaches % 

 to eye, length 3l^ in head ; mouth width 2% ; band of minute villiform 

 teeth in each jaw, none on palate; interorbital SVs, deeply depressed 

 concavely. Gill rakers 0+9, low points, lower 4 mere rudiments; 

 longest % of gill filaments, which 31/5 m eye. 



Two broad, flat, triangadar rostral spines, length li/o in eye; supra- 

 orbital ridge with slight notch over hind eye edge; broad, strong 

 suprascapular spine, length half of eye; ridge of suborbital stay 

 very feeble, only evident below eye, without spine at preopercular 

 angle; very small, short opercular spine, below lower eye edge; 

 large triangular humeral plate ending in a slender pointed spine 

 3 in head. 



Scales 56 in lateral line to caudal base ; 4 above until opposite sec- 

 ond dorsal origin, 16 below to anal origin; 7 predorsal. Chest, 

 breast, and region rather narrowly behind paired fins naked, also 

 prepectoral region. Most all of caudal finely scaled, though more 

 densely so basally. Along dorsal bases 24 strong bucklers, first 8 

 along spinous dorsal at first broad with their hind edges with sev- 

 eral serrae which progressively or at second fin form but a single 

 strong spine to each buckler. Lateral line conspicuous, rather high
