PARACHAETURICHTHYS 271 



Dorsal VI, 1-10 ; anal I, 9 ; there are 28 to 32 scales in a longi- 

 tudinal series, 9 in a transverse series, and 16 to 19 before first 

 dorsal. 



The body elongate, somewhat compressed, with deep, much 

 compressed caudal peduncle and large, broad head, the depth 5.1 

 to 5.5 times, the head 3.4 to 3.7 times in length ; the head broader 

 than deep, the blunt, broad convex snout 3.6 to 4 times in head ; 

 the eye equals or is slightly longer than snout; the eyes very 

 high up, dorsolateral, their gaze upward as well as sideways; 

 the interorbital 1.5 to 1.8 times in eye; the mouth slightly ob- 

 lique, the jaws equal, the posterior angle of maxillary beneath 

 anterior part of eye or front margin of pupil ; in upper jaw the 

 outer row is of enlarged, curved, caniniform teeth, followed by 

 a band of four rows of small, slender, depressible teeth, those 

 of the innermost row a little longer than the rest; the teeth of 

 lower jaw have the same arrangement, but those of outer row 

 are hardly as large as in outer row above, while those of the 

 inner band are coarser than those in upper jaw; rows of 

 slender barbels occur on underside of lower jaw, along median 

 line of chin and on the branchiostegal region ; the body covered 

 with rather deciduous scales, those on sides ctenoid, those on 

 nape, head, and anterior underparts cycloid, the scales extending 

 forward on head between eyes and almost to tip of snout; the 

 middle spines of first dorsal longest, extending upon second dor- 

 sal when depressed, 1.8 to 2 times in head; the second dorsal 

 and anal high, the latter slightly exceeding the former, angu- 

 late, the posterior rays longest, reaching caudal when depressed, 

 equal or nearly equal to depth, and 1.4 to 1.8 times in head ; the 

 depth of caudal peduncle 1.75 times in its own length, which 

 is equal to the depth ; the very long, pointed caudal longer than 

 head and 2.7 to 2.8 times in length; the pointed pectoral 0.1 

 longer than head; the ventrals broad, with a wide strong fre- 

 num, their margin incised, pointed, 1.3 times in head, the tip 

 never reaching anus; the anal papilla slender and pointed. 



The color in alcohol dusky brown, paler below, without dis- 

 tinct markings; the fins all dusky or blackish; a large, black, 

 yellow-margined oval ocellus lies on basal part of caudal, just 

 below its upper margin. 



Here described from a specimen, 51 millimeters long, collected 

 at Iloilo by Montalban in July, 1925, and seven specimens, 44 

 to 82 millimeters long, collected at Amoy, China, by Light.
