evidentally acute; anal with a gently concave margin, the second 

 spine rather slender, 4.1, 3.25 in head; ventral inserted very slightly 

 behind base of pectoral, 1.9, 1.75 in head; pectoral quite long, reaching 

 more than an eye's diameter beyond tip of ventral, the fifth and sixth 

 rays (counting downward) longest, 1.3, 1.25 in head, 3.9, 3.7 in length. 



Color of old preserved specimens grayish above, with bluish metallic 

 reflections; pale silvery below; rows of scales along side with rather 

 definite dark streaks; inner lining of gill covers pale silvery, with few 

 dusky points; fins, exclusive of ventrals, all more or less dusky; axil of 

 pectoral black, this color extending diffusely on inner side of fin. 



Only two specimens, 340 and 230 mm. (270 and 185 mm. to base 

 of caudal) long, both from Callao Bay, are at hand. The larger one 

 (U.S.N.M. No. 36934) has been designated as the type. The pro- 

 portions and enumerations given first in each instance apply to the 

 type. The specimens are only in fair condition, having been collected 

 by W. H. Jones in 1884. 



This species is very close to S. deliciosa, from which it differs chiefly 

 in dentition. In the present species the teeth in the upper jaw are in 

 a narrower band, and the outer ones are larger and in a close-set series; 

 and those of the lower jaw are in two principal series (not in a band), 

 with those of the inner series notably enlarged. The body apparently 

 is slightly deeper; the outline over the eyes is straight or slightly 

 concave, instead of gently convex ; the maxillary is a little longer ; the 

 scales are a little less numerous; and the pectoral is rather longer. 

 The small paratype, however, overlaps slightly with specimens of 

 S. deliciosa in all the characters mentioned, exclusive of the dentition, 

 and the length of the maxillary. The dentition in S. callaensis, in fact, 

 is in agreement with the large specimen herein identified as S. wieneri. 

 That species differs rather notably in having more numerous scales in 

 a lateral series and in having much shorter pectoral fins.
