230 WAITE 
Teeth.—Extremely small in narrow bands in both jaws, none 
otherwise in the mouth. 
Fins—tThe dorsal spines are low and recumbent, the first 
being inserted well behind the edge of the opercle: the last 
spine is the longest, being adnate to the first ray which is simple, 
the second ray is the longest, nearly half the length of the 
head; the following rapidly diminish to the eighth, whence they 
are of nearly uniform height: the anal commences beneath the 
thirteenth dorsal ray and its hinder insertion is posterior to 
that of the dorsal: the pectoral is long and falcate, nearly as 
long as the body is deep, and extending to the first spine of the 
anal: the ventral is short, its spine equals the length of the 
snout and eye, its anterior insertion is midway between the 
hinder edge of the orbit and the anal; the caudal is large and 
deeply cleft, with a narrow pedunele, its least depth being equal 
to the snout. 
Scales —Cyecloid and deciduous, those of the lateral lme more 
adherent: scales are present on the cheeks and opercles. the 
upper part of the head is naked but without pores: the lateral 
line follows the contour of the back and extends to the base 
of the caudal. 
Colours.—The head is brown above, vellowish on the sides and 
silvery beneath; eye with a bright golden mark before and 
another behind the pupil; the back, above the lateral line, is 
deep purple, and the sides are silvery with a pink tinge: a deep 
blue black blotch behind the head, crossing the lateral line but 
extending neither to the dorsal profile nor to the upper base of 
the pectoral: dorsal fin dark brown; pectoral and caudal with 
clouded edges, the latter reddish at the base. 
Length —553 mm. 
In his revision of the fishes of the Family Stromateidae, Mr. C. 
T, Regan?4 admits five species of Seriolella, and supplies a 
useful synopsis. 
Since that time Mr. E. C. Starks®> has described a new 
species taken at Callao, Peru, under the name Neptomenus 
crassa, and perhaps being unaware of or not admitting the 
eeneric identity with Seriolella remarks :—‘‘This is apparently 
the first record of the occurrence of this genus outside of 
Australian seas.’’ The species should be compared with 
S. violacea Guichenot, from the coasts of Chili.
