Description

(Form). Thicker in proportion to its length than the last species; the ventral carina not so prominent, causing the anterior part of the body to appear more hexangular than heptangular: number of transverse shields between the gills and the vent the same, but from the vent to the caudal only thirty-six or thirty-seven: head larger; the crown nearly flat, without any elevated ridge; the profile passing off almost in a straight line to the mouth, with very little sinuosity: snout every-way larger; longer, and, measured vertically, nearly as broad as the head; very much compressed: spinous process before the eyes smoother, and less projecting: head, including the snout, rather more than one-sixth of the entire length: opercle much larger: dorsal placed further back, being exactly in the middle of the entire length: anal very minute: caudal and pectorals similar.

Found in the same situations as the last species, and equally, if not more, common. Obs. I feel some hesitation in considering the S. Typhle of Bloch to be the same as that of English authors. His figure, as Donovan has observed, resembles more nearly the S. Acus in a young state.

I very much doubt whether this supposed species be any thing more than the young of S. Acus. During a stay at East Bourne, in Sept. 1833, 1 obtained three specimens, taken in the shrimp-nets at that place, which appeared exactly to coincide with Donovan's figure, but which, I am tolerably satisfied, are only what I have stated above. Two of these were females, and possessed an extremely minute anal fin; but the third, which was a male, exhibited no vestige of it whatever, even when examined carefully with a lens. In this last individual, though measuring only three inches and a half in length, the caudal pouch was full of newly-hatched young. What the S. pelagicus of Linnaeus may be, I do not pretend to say.

** Anal and pectoral fins wanting; caudal obsolete.
