greatest width of the dorsal tin equal to one-fourth the length of the 

 carapace; a supraocular spine pointing forward and a small spine in 

 the middle of the dorsal ridge on each side, and at the same point as 

 the latter a large spine somewhat curved backward in the middle of 

 the back; ventral ridges terminating in a strong spine, and on each 

 side between its base and the liase of the pectoral fin are 2 small spines 

 at equal distances. Head deep, profile above steep, convex, and with 

 snout projecting; mouth below gill opening small, with small pointed 

 teeth; lips thick and fleshy; eye high, 2 in snout, 2| in head, and If 

 in interor])ital space; interorbital space concave; gill opening short, 

 one-half in eye and posterior to it; base of the dorsal at the last fourth 

 of the carapace higher than anal; origin of anal midway between base 

 of last dorsal ray and end of carapace; caudal equal to space from 

 origin of dorsal to end of carapace, the lower raj^s the longer, and its 

 edge oblique; pectoral with upper raj's the longest and equal to snout; 

 caudal peduncle rather thick, 2 in snout. 



Color in alcohol brownish, lighter below, and with many l)lack spots 

 all over the upper surface, small on the back and large on the poste- 

 rior and lateral parts; some few dark spots at the margins of the ven- 

 tral ridges; fins pale; caudal peduncle dark above, with several dark 

 spots; a dark spot at base of pectoral and one on caudal peduncle l)elow 

 at base of lower caudal ray. Length -ij-g inches. In a small specimen, 

 If inches in length, the spines are much longer and stronger, though 

 absent from the ventral ridges, except the last one on each side; snout 

 projecting considerably; gill opening very small, color with spots 

 mostly replaced by narrow, dark, curved lines. Here described from 

 .Misaki specimens. It was not taken elsewhere by us. 



This species, common throughout the East Indies, ranges occasion- 

 ally northward in the Kuro Shiwo to Japan. We have a single large 

 example from Misaki, and Bleeker records this fish from Nagasaki. 

 The species is readily known by its short frontal spines and the trans- 

 lucent carapace.
