The British Museum possesses a Chinese specimen. One spine can be observed incumbent 
on the front of the dorsal, but the other three are concealed. The specimen measures 144 
inches, the figure nearly 11. There is a greater’ distance between the anus and anal fin in 
this species than in the preceding one. The lateral line is decidedly keeled, and the fins are 
less pointed than they are represented to be in Bloch’s fig. 160, and much less than in his 
plate 422. The colour is yellowish-gray with lilac and purple tints by no means dark, so 
that the name of niger is not appropriate.

SESERINUS VACHELLII, Richardson. Rad. D. 5/42; A. 3/37; C. 1712; 
P. 21; V.1|5. (Spec. Camb. Ph. Inst.) 
This fish has the same close resemblance to Stromateus niger that Seserinus microchirus 
has to Stromateus fiatola. The Prince of Canino has replaced the Mediterranean Seserinus 
in the genus Stromateus, but the discovery of the Chinese species with larger ventrals and a 
keeled lateral line justifies Cuvier’s separation of the two forms. The Rev. George Vachell 
brought two specimens from Canton of the Seserinus which we have named in honour of him. 
It isa greatly compressed fish, which is thickest at the orbits, the height of its body being only 
a quarter less than the length, caudalexcluded. The acute nuchal ridge vanishes in the inter- 
orbital space, which is however not flat. A recumbent spine is placed in front of the dorsal, and 
five erect ones are so buried in front of the fin that they can be detected only by dissection. 
The fifth spine has a long, flexible, but not jointed tip, which is also concealed; the others are 
pungent. The first anal spine is short, the third one a quarter of the length of the soft rays, 
and the second one of intermediate length. Both the dorsal and anal are falcate. The pec- 
torals are long and falcate, their tips reaching over two-thirds of the anal. Ventrals small, 
falcate or pointed, attached beneath the corner of the preoperculum, and having the anus be- 
tween their tips. Tail slender, caudal deeply forked. Scales small, the lateral line torulose 
or keeled on the tail by soft triangular plates, which have an acute point that catches the fin- 
ger when drawn back. These plates are small, and when examined with a lens appear to be 
formed of two divergent tubes, with the acute point rising from the disc they enclose. 
Eye distant from the profile. Preoperculum and operculum striated. Lower jaw when 
depressed longer than the upper one. Teeth as fine as hairs, slightly curved in one close row 
on both jaws. Colour gone. 
Length 3:75 inches. Height of body between dorsal and anal, 2 inches. Length of head, 
1 inch.
