NO. 2149. JAPANESE MACROVROID FISHES— GILBERT AND HUBBS. 155 



Further differences between our specimens and the type, and be- 

 tween specimens of different size, are tabulated below. 



Ninety-five pyloric caeca were counted in the specimen 190 mm. 

 long. 



First dorsa], pectoral, and ventral fins dark, overlaid with bluish- 

 gray pigment ; the pectoral and ventral with elongate dark spots. 



In the young specimens, 68 and 76 mm. long, the snout is blunter 

 than in the adult; the first dorsal spine better developed, sharp 

 instead of concealed; the pectoral and dorsal filamentous rays shorter, 

 and the outer ventral ray longer. These differences are indicated in 

 the table of proportional measurements. The pseudobranchial fila- 

 ments are conspicuous in the young, small in the specimen 190 mm. 

 long, and absent in the specimen 302 mm. long, and in the type, 332 

 mm. long.
