136 FISHES. 



that might be taken for a vestige of the ventrals*. Besides this, there 

 are the trenchant blades of which we have just spoken, and there is eveu 

 one species in which these blades are crenated-f-. 



LuvARUs, Rafin., 



Appear to be closely approximated to Peprilus; the extremity of the pel- 

 vis is furnished with a small scale that acts as an operculum to the anus; 

 no trenchant blades; a prominent carina on each side of the tail, as in 

 the Tunny, &c. 



Luv. imperialis, Rafin. Ind. d'lttiol. Sicil. pi. i, f. 1. Silvery, 



with a reddish back ; an extremely large species that inhabits the 



seas of Europe ;{:. 



Seserinus, Ciw., 



Have all the characters of the Stromatei, even internally; but on them 

 are seen two small ventrals, or rather vestiges of ventrals. 



Ses. Rondeletii, Cuv. ; Rondel. 257. A small species from the 

 Mediterranean. 



KURTUS, Bl. 



The Kurtes are closely allied to Peprilus, from which they particularly 

 differ in the less extent of their dorsal, and in the development of their 

 ventrals : the anal is long, the scales are so extremely small that they are 

 hardly visible till the skin is dried ; there are none on the fins ; seven 

 rays in the branchiae ; a pelvic spine between the ventrals, and several 

 small trenchant blades before the dorsal, at whose base is a spine directed 

 horizontally forwards. 



A singularity of structure is presented in their skeleton ; the ribs are 

 dilated, convex, and form rings which are in contact with each other, thus 

 enclosing a conical and empty space, wiiich extends beneath the tail, in 

 the inferior rings of the vertebra, in a long and thin tube which contains 

 the natatory bladder. The 



Kurt, indicus, Bl. 1G9, is very probably the female of the Knrtus 

 cornutus, or Somdrum-Kara-Mottee of Russel, a fish very remark- 

 able for a little cartilaginous and curved horn, which rises from the 

 first of the small trenchant blades before the dorsal. 



CoRYPH^NA, Lin. 



The Coryphoena, vulgarly called Dories, and, by the Dutch, Dolphins: 

 the body compressed, elongated, covered with small scales; upper part of 

 the head trenchant; a dorsal extending along the whole of the back, 



*'CheBtodon ahpidotus, L.,or Stromateus longipinnis, Mitch.; — Sir. cryplosus, Mitch.; 

 — Sir. paru, Sloane, Jam. II, pi. eel, f. A. 



f Peprilus crenulatus, Cuv., a small and new species. 



X A specimen was taken at the Isle of Re, in 1826, a drawing of which was for- 

 warded to us by M. Journal Rouquet, one of the custom-house officers of that 

 island. I suspect that we should refer to it, at least as a'congener, the Atisonia Cu- 

 vieri, Risso, 2nd ed. pi. xi, f. 28, which is figured, however, with two anal spines.
