total length (without caudal), the length of the head four times. Snout shorter than the 

 eye, the diameter of which is one-fifth of the length of the head ; lower jaw prominent ; 

 maxillary as long as the eye ; the upper jaw with a series of fifteen truncated teeth on 

 the blind side, none on the other ; eyes separated by a very narrow space covered with 

 rudimentary scales. Scales small, cycloid, imbricate, larger about the lateral line than 

 elsewhere ; the anterior curve of the lateral line is strong in the adult specimen, but 

 much more open in the young one ; its width equals the length of the pectoral ; pectoral 

 more than half as long as the head ; ventrals entirely separate ; fin-rays smooth ; the 

 dorsal commences immediately behind the front margin of the orbit. The free portion of 

 the tail much higher than long. Gill-rakers very short ; about ten on the first branchial 

 arch. Blackish-brown, uniform, or indistinctly mottled with darker. In the young 

 sjjecimen the rays of the vertical fins are dotted with brown, five or six of them, of the 

 dorsal as well as of the anal, having a broad black ring. In the adult example those fin 

 rays are uniformly coloured, only traces of the dark rings being still visible. Length, 

 12 inches. Inland Sea, Japan. Yokohama Bay; 15 fathoms.

Cynoglossus interrujjttis, n. sp. (PI. XXX. fig. B). 



D. 106, A. 77-85, L. lat. 78. Two lateral lines on the left side, the upper of 

 which is discontinued at the end of the anterior third of the body. The lateral lines are 

 separated at the j)oint of their greatest distance by twelve longitudinal series of scales. 

 No lateral line on the blind side. Two nostrils, one immediately in front of the eyes, 

 the other above the middle of the uj)per lip. Eyes close together, the upper somewhat 

 in advance of the lower. Li|)s not fringed. The angle of the mouth is below the middle 

 of the eye, much nearer to the extremity of the snout than to the gill-opening. The 

 rostral hook terminates below the symphysis of the mandibles. The height of the body 

 is contained thrice and three-fourths in the total length, the length of the head five 

 times and one-third. Brownish, irregularly speckled with brown. Fin-rays dotted with 

 brown. Length of specimens, 6 inches. Market at Yokohama.

 p. 486). 



D. 106-107, A. 79, L. lat. 85. Three lateral lines on the left side; on the level 

 of the end of the abdominal cavity the upper and lower lines are separated from the 

 middle by thirteen rows of scales ; four series of scales between the dorsal fin and the 

 upper lateral line, and four between the anal and lower lateral line. No lateral line on
