Color in spirits yellowish Avhite, diisk}^ above, the dusky color 
abruptly ceasing along the middle of the third row of scales below the 
dorsal fin; a dusky band bordered by blackish extending from tip of 
snout through eye and on head; it can be indistinctly traced to the 
upper part of caudal peduncle, where it ends in a small dark blotch. 
Described from a specimen l-iO mm. long from Nagasaki. 
This well-marked species is distinguished by its slender body and ))y 
the presence of but 3 rows of scales on the cheek. It seems to be 
rare. We have but 2 specimens from Nagasaki and Misaki.

12. ANAMPSES Cuvier. 
Anmnpses Cuvier, Regne Anim., 2d ed, 1829. {tetrodoa; cuvleri, the characters 
taken from the latter species; the former perhaps a T'dapia). 
Ampheces Jordan and Snyder, new subgenus {geographicus). 
Body oblong, rather deep, compressed, covered with moderate or 
large scales (25 to 30 in the lateral line, about 50 in subgenus Ampheces)', 
lateral line continuous; head scaleless; preopercle entire; teeth uni- 
serial; two anterior canines in each jaw prominent, turned forward, 
compressed, with cutting edges; no posterior canines; fin rays D. IX, 
12; A. Ill, 12. Species of rather large size and showy colors, of the 
East Indies and Polynesia. The group is naturally divisible into two 
groups distinguished by the size of the scales. The Japanese species 
constitutes the new subgenus or probably distinct genus Ampheces^ 
distinguished from Anam/pses by the small scales.

Dorsal ra3^s IX, 12; anal rays III, 12; scales in lateral line 50; in 
transverse series 8+22. 
Dorsal spines stiff. Brownish violet, each scale with a blue vertical 
streak; head, thoracic region, and caudal lin Avith reticulated, blue, 
darker edged lines. Vertical fins with a yellow hue and black margin; 
dorsal and anal with numerous small blue dots (Cxiinther). 
This species is placed in the present list because a specimen from 
Riukiu is in the Imperial Museum of Tokyo. It is regarded by us as 
the t3"pe of a distinct subgenus AinpJuces^ distinguished from A?ia)npses 
by the small scales (50 instead of 30).
