branch extending across occiput; two accessory branches on head, one 

 of which is beneath the eye, the other extending downward to edge 

 of opercle. 



No spinous dorsal present. Soft dorsal and anal inserted on a ver- 

 tical passing just posterior to anal opening and decidedly nearer tip of 

 snout than base of caudal; the middle rays of both fins nearly equal 

 in height, about three in head; the posterior rays of anal growing 

 longer posteriorly so that they reach slightly beyond base of caudal 

 when depressed. Caudal pointed, the length contained about 1.5 

 times in length of head. Pectoral pointed, 1.25 in head, the tip 

 reaching beyond origins of dorsal and anal. Posterior rays of 

 ventral longest, two in head. 



In alcohol, pale flesh color, finely marbled and speckled with 

 brown; immaculate beneath; dorsal, caudal, and upper pectoral rays 

 spotted with brown. 



The species is represented by three specimens measuring 35 mm. 

 in length. They were found entangled in a great seine drawn by 

 fishermen on the sandy beach near Tomakomai in Hokkaido, at the 

 request of Prof. S. Nozawa.

HIPPOGLOSSOIDES KATAKURjE, new species. 



This species may be distinguished from H. dubius, H. elassodon, 

 and H. hamiltoni by the more abrupt and higher arch in the lateral 

 line, there being six or seven rows of scales between its uppermost 

 part and the horizontal; by the deeper body, the dorsal contour 

 being accordingly more arched. There are more rays in the dorsal fin 

 of K. Jcatakurse, it having 90, while the other closely related species 

 have not more than 85. The ventral fins of the new species are 

 pointed, and the dorsal originates slightly in front of the eye. 



Head 3.8 in length to base of caudal; depth 2.5; depth of caudal 

 peduncle 9; eye 4.7 in head; snout 5.5; maxillary 2.5; D. 90; A. 69; 

 pores in lateral line 93; transverse series of scales 100. 



Body dextral; dorsal contour rather strongly arched from a point 

 above the eye, thus giving the anterior parts a more obtuse appear- 

 ance than is common to other Japanese species of the genus. The 

 upper eye is placed well in advance of the lower; the interorbital space 

 rather broad, with four rows of minute scales at its narrowest part. 

 Maxillary extending to a vertical passing midway between posterior 

 edge of eye and pupil. Teeth small, slender, in a single row on the 

 symphysis, where they are irregularly placed, enlarged and somewhat 

 canine-like. Gillrakers long, flat, and rather slender, 3+12 on the 

 first arch. Vertebrae 41.
