fourth spines are slender and flexible. Pectoral fin long and large, the 

 distal end of which reaches the third spine of the anal fin or much 

 more backwards. Posterior and lower margin of the pectoral concave. 

 5 or 6 rows of scales between the preorbital and the inner ridge of the 

 preoperculum. Limb of the preoperculum entirely naked. Pyloric cceca 

 4. Teeth weakly developed (PL VII. fig. 3). Both jaws have 2 rows 

 of small conical teeth. Outer row has no grinding teeth. Only a few 

 grinding teeth in the inner row. 6 — 1 5 teeth on the vOmer (PI. V. fig. 

 1). They are conical, slender and grow in a round group.* Frontals 

 separate, porous like a honey comb. Occipital crest long and very thick, 

 thickest near the anterior end (PL V. figs. 1 — 3). First spurious inter- 

 neural slender (PL VII. fig. 3, c). Coloration in general resembles that 

 of P. major; but it is much brighter. Posterior margin of the operculum 

 dark red. Iris partly brown, partly silver white. Grows to a length 

 of about half a metre. Fish, commonly found in the market is about 

 30 cm. long and about 1 kilogramme in weight. 



Geographical distribution. Japan, Kiushu, southern coast of Shikoku, 

 northwestern and northeastern coasts of Hondo ; China ; Corea. 



Vertical distribution. Depth of 10 — 150 metres. This species does 

 not come to shallow water in the spawning season. 



Profile of the head of this species is different in different sexes. In 

 the male the occipital crest is rectangular, so that the forehead is very 

 prominent. In the female, on the other hand, the occipital crest is 

 triangular and the forehead is beautifully arched. 



Food and habitat are about the same as P. major. Caught chiefly 

 by lines. 



Known under various names, such as chidai, chikodai, hirekodai, 



hirenaga, kundai, hanadai, etc. 



* Mr. Takashi Nakamura of our bureau collected an extraordinary skull of this 

 species which wants these vomerine teeth at all. This will be the skull of a hybrid 

 between P. major and P. cardinalis.
