with pores.) A dark band along the middle of the tail; vertical 

 black streaks between the dorsal rays.

4. Opsariichthys pachyceplialus. 



Closely allied to 0. temminclU, but with the suborbitals consider- 

 ably broader. 



D. 10. A. 13. L. lat. 55. L. transv. 12/G. 



Mouth rather wide, the maxillary extending somewhat beyond the 

 vertical from the front margin of the eye. Snout longer than the 

 eye, which is two-ninths or one-fifth of the length of the head. The 

 four or five anterior branched anal rays arc elongate, extending to, 

 or nearly to, the root of the caudal, if laid backwards ; dorsal fin 

 rather small, its origin being opposite to the root of the ventral, and 

 somewhat nearer to the root of the caudal than to the end of the snout. 

 Caudal fin deeply forked. Pectoral not extending to the ventral. The 

 length of the head is contained from thrice and a half to thrice and 

 three-fourths in the total length (without caudal), the height of the 

 body from thrice and three-fourths to four times and a half. Sub- 

 orbital ring of moderate width, the second and third bones being 

 half, or more than half, as broad as the orbit. Snout without 

 grooves or pores. Four longitudinal series of scales between the 

 lateral hue and ventral fin. Coloration uniform silvery ; a vertical 

 black streak on each interspace between the dorsal rays. (Pharyn- 

 geal teeth 5.3. 1—1 ,3.5.)

D. 9. A. 12. L. lat. 42-44. L. transv. 9-10/6. Vert. 20/20. 

 Mouth of moderate width, the maxillary extending to the vertical 

 from the front margin of the orbit. The four anterior branched 

 anal rays are more or less prolonged, sometimes extending beyond 

 the root of the caudal, if laid backwards. Also the pectoral is some- 

 what elongate in adult examples. The height of the body is nearly 

 equal to the length of the head, which is contained four times and 

 one-third in the total (without caudal). The origin of the dorsal fin 

 is a little nearer to the end of the snout than to the root of the 

 caudal. Suborbitnl ring very narrow. Body with about twelve 

 more or less distinct bluish cross bands, which are broader than the 

 interspaces between them. A vertical elongate black spot in each 

 interspace between the anterior dorsal rays. Snout in certain adult 

 specimens with round grooves (pores). 

 Japan ; Formosa.
