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 under pectoral base, their inner rays separate and adnate to either side 
of a shallow groove extending back to anus. 
Seales 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.

fig. VI, Yokohama). 
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 It was originally made known by Cristoforo 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
