fins are very long and falciform; tlie first false fin beneath is connected withthe anal; it attains the length of ten feet.
Pelamys orientalis differs from P. chilensis, C. V., in the much shorterpectoral fins, D. 18, 14 + 8 ; A. 12 + 1 + 8. The last two false finsonly are free.
Cybium chinense and niphonium are described and figured in the samework, as well as Trichiurus lepturus japonicus.
Histiophorus orientalis, new species, differs from indicus in the elevatedforehead and in the dorsal fin being much lower anteriorly than in themiddle.
Placate bivittata, which was described by Cuv. Valenc. from a youngspecimen, is here figured and described in the full-grown state.
Chorinemus orientalis, Schl., would appear to correspond very nearly withCh. mauritianus, C. V., differing from it only in the teeth of the lower jaw,the external row of which is directed horizontally outwards.
Trachinotus anomolus, Schl., has only four spines in the first dorsal fin,and the anterior part of the soft dorsal and anal fins are not elongated atthe tip ; the skin is divided into irregular areas. The fish might probablyconstitute a separate genus, it has, however, been instituted merely from adrawing.
Amongst the figured species of the genus Caransc, is a Trachurus, whichSchlegel does not separate from Caranx trachurus; it appears to approachthe C. declivis of Jenyns very nearly, at least the number of the lateral.plates and of the fin-rays pretty nearly corresponds.
Of Caranx with a false fin, two species have been described and figured.C. muro-adsi, D. 8, 1 + 33 ; A. 2, 1 + 27, and C. maru-adsi, D. 7, 1 + 34 ;A. 2, 1+ 28.—Lastly, in the division without false fins two species havebeen instituted: C.flavocceruleus and C.equula.
In the family of the Tcutliyidse, four species of the genusAmphacanthus have heen described hy Sal. Muller andSchlegel: A. dorsalis, corallinus, viryatus, and vermiculatus.(Verhandelingen, &c.)
Anastasio Cocco has described, in the 25th Part of the Giornale delGabinetto di Messina, January 1844, a new genus of the Tssnioidei, underthe name of Krohnius; snout short, mouth cleft obliquely, body elongated,head obtuse, teeth in the maxilhe, a barbal cirrus on the elfin, anus nearthe head, first dorsal fin short and high, the second extends the wholelength of the back as far as the extremity of the tail, as also does the analfin. The rays of the ventral fins prolonged into long filaments: K.fila-mentosus, D. 8, 150; A. 100, P. 20, V. 8. B. 7. 2 inch. Messina.
The same naturalist has instituted (ib.) two other new genera, whichwould appear to constitute a peculiar small family. The one, Bibronia, is
