JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 243 



Body soft, with little firmness; dorsal and ventral contours evenly arched; 

 body compressed, especially at bases of dorsal and anal; depth of caudal peduncle 

 4.5 in head, dilating posteriorly at base of rudimentary rays; head blunt, sides flat, 

 as is dorsal surface; snout vertical in profile at tip; jaws equal, lower series of teeth 

 included; maxillary short, not reaching eye, completely hidden by preorbital; 

 teeth in lower jaw close-set, cardiform, somewhat arrow-shaped, with fine antrorse 

 serrations on each edge; diminishing quickly in size at mandibular symphysis; the 

 teeth in the upper jaw widely set and irregularly placed, lacking posteriorly; teeth 

 on upper pharyngeals fine, slender, and not thickly set. 



Dorsal composed of two fins, base of first 1.5 in head, of second 1.5 times 

 length of head; outline of first somewhat rounded, of second parallel with fin- 

 base; height of both dorsals equal to eye; caudal forked; middle rays half length of 

 outer; anal similar to second dorsal and of equal height, its insertion under that of 

 latter; pectoral extending to midway between vent and anal insertion; ventrals 

 inserted imder pectoral base, their inner rays separate and adnate to either side 

 of a shallow groove extending back to anus. 



Scales small, cycloid, present on cheeks, opercles, pectoral and caudal bases, 

 and body, very deciduous; lateral line two-thirds of eye-diameter below dorsal base, 

 with which it is parallel. 



Color uniformly dark; fins black; peritoneum and lining of mouth-cavity black.

Sagami Bay, No. 6024a (from Owston Collection). 



This specimen represents a second species of the singular genus Caristius, 

 obtained from the shores of Japan. It was originally made known by Cristoforo 

 Bellotti in 1905, under the name of Pteraclis macropus. 



The specimen before us, from the Kuro Shiwo off Sagami Bay is, however, 

 plainly a member of the genus Caristius, and at the same time distinct from Caristius 

 japonicus. The following description of this specimen was drawn up for Professor 

 Edwin Chapin Starks. 



Dorsal rays 34; anal 22; pectoral 18; ventral I, 5. Head 3 in length; depth of 

 eye 2. Eye 2.33 in head; maxillary 1.66. Body and fins extremely fragile. 



The form is much compressed, elevated to a rounded angle above eye, sharply 

 declivous in front of eye, and sloping backward in a straight line (straighter than
