This small and fragile species is represented in the collection by 
58 specimens, varying in length from 27 to 70 mm. to the anus; 18 
females, in which the heads measure from 41 to 52 mm., have ripe 
or ripening ova. It is one of the most distinct species of the notatus 
group, being distinguished from all of the others by its larger scales, 
_ and from those species without a ventral fossa in numerous other 
characters; the orbit is larger, the snout of different form, and the 
squamation different in many details. 
Fin-rays—first dorsal, II, 9 (8 to 19 in paratypes) ; pectorals, 
17 (or 16) ; ventrals, 7 (constant). 
This is a slender form, with an arched dorsal contour more notably 
elevated than usual at the origin of-the first dorsal fin. The greatest 
depth is contained 1.8 (to 2.0) times in the head; the width across 
the bases of the pectoral fins, 2.5 (2.4 to 3.00) times, being a little less 
than the depth of the body below the origin of the lateral line. In 
distinction from all other species of the notatus group, with the ex- 
ception of maculatus and velifer, the dorsal contour of the snout is 
almost straight. The suborbital and preorbital portions of the infra- 
orbital ridge are straight in outline; the ethmoid region is evenly 
convex. The width of the snout across its anterolateral angles is 
greater than the length of the snout before the angle. The dorso- 
terminal plate varies widely in its length, which is contained from 
3.0 to 4.3 times in the postorbital (3.7 times in the type). The sub- 
opercle ends below and behind in the usual pointed flap. The inter- 
orbital space is wider than in dorsalis or argus, and the suborbital 
is markedly broader. The maxillary extends backward a little be- 
yond the vertical from the middle of the orbit. The teeth are villi- 
form on the jaws; the outer premaxillary series is scarcely enlarged; 
the barbel is short and slender. Six branchiostegals; gill-membranes
