membranes; the anus less remote from the origin of the anal. Cor- 

 related with these differences is the difference in bathymetric dis- 

 tribution of the two species, as this form inhabits much deeper water 

 than O. coUettl. 



The single young specimen obtained differs from our larger Philip- 

 pine specimens of B. multifiUs^ chiefly in the longer gill-rakers, 

 which are nearly as long as the interorbital width; and in having 

 fewer pyloric caeca, 16 instead of 35 to 52. 



First dorsal, II, 9; ventral, 8; pectoral, 16; gill-rakers 6-|-27, in- 

 cluding the most anterior gill-raker (which is tubercular). 



Measurements in hundredths of length to anus (35 mm.) : Length 

 of head, 62; length of orbit, 16; least width of interorbital, 14; least 

 width of suborbital, 8; distance between orbit and preopercle, 28; 

 length of snout, 19; distance from center of anus to base of outer 

 ventral ray, 38 ; distance from base of outer ventral ray to isthmus, 

 27 ; length of first dorsal base, 19 ; length of second pectoral ray, 107 

 (the second dorsal spine and outer ventral ray also thickened, and 

 evidently produced, but broken in the specimen at hand) ; length of 

 longest gill-rakers, 13.

In our specimens the coracoid f oram.en is in the suture between the 

 hypercoracoid and the hypocoracoid, contrary to the original de- 

 scription, in which the hypercoracoid is said to be perforate. The 

 lateral line is angulated anteriorly as in the other species of the genus, 

 not " rising anteriorly by a gently concave curve." On the tail, the 

 lateral line is below the median line of the body, abruptly rising an- 

 teriorl}^ above the anus, in the direction of the end of the first dorsal, 

 for a distance equal to the length of the snout, thence forward to the 

 nape, along a line which is slightly curved downward.
