.straight: inner flap at gill-opening* equal in length to the outer, pro- 
trudnig a little; no.strils .separate, in an oval elevation. 
Lateral fold })re,sent. A line of nuicoas pores extending from a 
point behind the mouth backward, below, and close to the eye, passing 
in a broad curve above the pectoral, bending downward and running 
to the middle of base of caudal; a branch passing over nape just above 
gill-opening; another leaving the lateral line behind the eye, going 
downward and disappearing on the throat; a third, having its origin 
immediately ]»ehind the latter, going upward and forward, passing 
downward close behind the nostrils, and joining the lateral line; a 
branch crossing the snout above; a line extending along side of body, 
below lateral fold, from a point below tip of pectoral to base of caudal; 
no inclosed quadrangular space behind e3^e. Skin smooth. 
Dorsal and anal tins pointed, the edges straight or slightly concave; 
of about equal height; If in head. Caudal 1| in head, subtruncate, 
the upper lobe slightly pointed, the lower somewhat rounded. Pec- 
toral -2.^ in head; of 13 rays. 
Color light gray, abruptly white below; back covered with close-set 
black spots mostly smaller than the pupil and broader than the inter- 
spaces which form reticulations around them; numerous small spots 
below the eye; spots largest on upper part of tail, some of them con- 
fluent; spots on upper part and below Ijase of dorsal mostly confluent, 
forming elongate blotches. Caudal dusky posteriorly; edged above 
and below with pale; other fins grayish. 
Tokyo Bay. Known from one specimen about 325 mm. long. Type 
No. 6523, Leland Stanford Junior University Museum. 
It is distinguished from S.pardalis by the smaller, closer set spots, 
the general gray coloration, and the more concave caudal. From 
S. sficfonotxs it difi^ers in color, in having smooth skin, less falcate 
fins, and fewer dor.sal and anal rays. (Named for James Francis 
Abbott, of Hachiman. fJapan, formerly of Leland Stanford Junior 
University, in recognition of his studies of Japanese animals.) 
II. SPHEROIDES EXASCURUS Jordan and Snyder, new species. 
Head 3^ in length, depth 1^; depth of caudal peduncle 3^ in head; 
eye 1; snout 2f ; interorbital space 2^; dorsal rays 12; anal rays 12. 
Body moderateh' elongate, not broadened anteriorly; caudal pedun- 
cle not compressed, its length slightly less than that of head; length 
of head much less than distance between gill opening and insertion of 
dorsal. Eye large, 1^ in snout. Interorbital .space concave; distance 
between e3'es a little more than twice their diameter. Nostrils separate, 
in an oval elevation. Teeth bluntly pointed anteriorly, the cutting 
edges concave, the suture without a deep groove; ridges on either side 
of groove scarcely perceptible. Lower jaw projecting beyond the 
upper.
