until they are scarcely able to flop. The air is taken into the large, 

 thin walled, distensible stomach and apparently retained by the con- 

 striction of the muscular waUs of the cardiac end. There are 25 

 pyloric caeca. There is an enlarged, short rectum. No air bladder 

 is present. The liver is large and consists of but a single lobe.

PSEUDORHOMBUS CINNAMOMEUS (Temminck and Schlegel).

It is the belief of the writer that this species and P. misakius Jordan 

 and Starks are synonymous. The latter appears to differ from P. 

 cinnamomeus as figured and described by Temminck and Schlegel, in 

 having ocelli above and below the lateral line. These are much less 

 prominent than the one located on the lateral line near the tip of the 

 depressed pectoral, and they often grow less so with age, as is well 

 illustrated by a small series of specimens. The white-bordered ocellus 

 on the lateral line persists and it, together with the smooth scales of 

 the blind side, serves to distinguish the species from P. oligodon 

 (Bleeker), a specimen of which is referred to as P. cinnamomeus in 

 the description of P. misakius. 



PSEUDORHOMBUS OLIGODON (Bleeker). 



Specimens were taken with the seine at Shimizu. They have 75 to 

 80 rays in the dorsal and 58 to 64 in the anal. The scales are ctenoid 

 on both sides of the body, 82 to 86 lateral series; 76 to 80 pores in the 

 lateral line. The giUrakers are comparatively heavy and short, the 

 length being less than that of the filaments ; 8 or 9 on the lower limb 

 of the first arch. The eyes are large, the diameter of the upper being 

 equal to the distance from edge of orbit to the tip of snout. The fins 

 have many small, dark spots, and there is a brownish spot, varying in 

 distinctness, located on the posterior part of the curve of the lateral 

 line. Small specimens have rows of indistinct ocelli on the dorsal and 

 ventral parts of the body. The specimens from Tsuruga mentioned 

 by Jordan and Starks * are representatives of P. oligodon and they 

 do not differ in any way from an example of the same species from 

 Formosa.^
