fins all low ; there are no free silky rays on pectoral ; the caudal 

 rounded, shorter than head; the gill openings rather wide but 

 not extended forward, the isthmus broad; branchiostegals 4. 

 Dorsal VI, 1-10 or 11 ; anal I, 9 to 11. 



A single species is known from the coasts of China and Japan ; 

 specimens in the Vienna Museum are from the Philippines or 

 Celebes.

Dorsal VI, 1-10 ; anal I, 9 ; there are 38 scales in a longitudinal 

 series, and 15 in a transverse row in my specimens; Giinther 

 found 35 in the length, Jordan and Snyder 36, and Rendahl gives 

 35 and 12 for the number in longitudinal and transverse series. 



The body robust, the posterior part strongly compressed lat- 

 erally, more rounded anteriorly, with a very large, broad, de- 

 pressed head, the dorsal profile arched, highest before first 

 dorsal, the ventral profile nearly horizontal ; the depth 4.1 to 4.5 

 times, the head 3 or 3.1 times in length; the cheeks very much 

 wider than the narrow opercles and very bulging, making the 

 breadth of head much greater than its depth and 0.85 to 0.91 

 of its own length; the edge of suborbital has a row of barbels 

 with a shorter row beneath it, both extending across cheek more 

 than halfway; the lower jaw has a double row of barbels which 

 continue upward, one along margin of preopercle and one on 

 anterior margin of opercle ; there is a barbel beside the tubulate 

 anterior nostril; a fleshy flap behind eye conceals a large pore; 

 two similar flaps above opercle likewise conceal large pores; 

 the snout broad, bluntly rounded, 3.25 to 3.5 times in head; 

 the eyes small, very high up, dorsolateral, and looking up as 

 much as laterally, a little more than twice in snout, far 

 apart, 2 to 2.25 times in the broad, flat, interorbital space; the 

 mouth moderately large, broad, slightly oblique, the lips thick 

 and fleshy, the posterior angle of maxillary reaching a point 

 below middle of eye or beyond, in some extending much past eye ; 

 in most of my specimens the lower jaw projects, though other 

 authors state the jaws are equal; the teeth are in two rows in
