ICHTHYOLOGY. 559 



fins are very long and falciform ; the first false fin beneath is connected with 

 the anal ; it attains the length of ten feet. 



Pelamys orientalis differs from P. chilensis, C. V., in the much shorter 

 pectoral fins, D. 18, 14 + 3 ; A. 12 + 1 + 8. The last two false fins 

 only are free. 



Cybium chinense and niphonium are described and figured in the same 

 work, as well as Tricliiiirus lepturus japonicus. 



Histiophorus orientalis, new species, differs from indicus in the elevated 

 forehead and in the dorsal fin being much lower anteriorly than in the 

 middle. 



Elacate bivittata, which was described by Cuv. Valeric, from a young 

 specimen, is here figured and described in the full-grown state. 



Chorinemus orientalis, SchL, would appear to correspond very nearly with 

 Ch. mawritianus, C. V., differing from it only in the teeth of tne lower jaw, 

 the external row of which is directed horizontally outwards. 



Tmcliinotus 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 at 

 the tip ; the skin is divided into irregular areas. The fish might probably 

 constitute a separate genus, it has, however, been instituted merely from a 

 drawing. 



Amongst the figured species of the genus Caranx, is a Trachunis, which 

 Schlegel does not separate from Caranx tracJmrus ; it appears to approach 

 the C. declims 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. mam-adsi, D. 7, 1 + 34 ; 

 A. 2, 1+ 28. Lastly, in the division without false fins two species have 

 been instituted : C.flavoccemleus and C.equula. 



In the family of the Teuthyidse, four species of the genus 

 Amphacanthus have been described by Sal. Miiller and 

 Schlegel : A. dorsalis, corallinus, virgatus, and vermiculatus.

Anastasio Cocco has described, in the 25th Part of the Giornale del 

 Gabinetto di Messina, January 1844, a new genus of the Tseuioidei, under 

 the name of Krohn'ms; snout short, mouth cleft obliquely, body elongated, 

 head obtuse, teeth in the maxilla?, a barbal cirrus on the chin, anus near 

 the head, first dorsal fin short and high, the second extends the whole 

 length of the back as far as the extremity of the tail, as also does the anal 

 fin. 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, which 

 would appear to constitute a peculiar small family. The one, Bibronia, is
