whole length, and much laterally compressed. The lateral line is 

 distinct ; but the dorsal and anal fins are not very high. 



1\I. L. Kiener brought this extremely-interesting species from 

 Toulon, ill IMarcli, l^^viO ; and I have named it after him as a mark 

 of esteem and friendship.

64. Anquilla Cdvieri. 



Tliis name I bestow on the Pimperneaux, of which Cuvier cor- 

 rectly says, " that it has a proportionally shorter snout than the 

 other eels, and larger eyes." In comparison with the two following 

 species, however, which were unknown to Cuvier, it has rather 

 small eyes, their diameter being somewhat shorter than the length 

 of the snout. It is distinguished from the two succeeding species, 

 (1) by having a much stouter and higher form; ("2) by the back, 

 down to the lateral line, being dark green, while the whole ventral 

 surface under the line is silvery. The dorsal fin, which may be 

 called low, is lighter green, with a brighter edge ; whilst the anal fin 

 is yellowish. Pectorals, yellowish outside, olive-green interiorly. 

 Anus yellowish. 



Length, 18-50 in. Length of tail, 11-61 in. Diameter of the 

 eye, 0-28 in. Length to angle of the mouth, 0-51 in. To the 

 pectoral, 2-08 in. To the dorsal, 5-12 in. Height of the body, 

 110 in.

Since this species does not inhabit England, the synonym of 

 " L. anguille pimperneaux" must be withdrawn from the latirostris 

 of Yarrell. (Brit. Fishes, ii., p. 208.) 



65. Anguilla Bibroni, fig. 16. 



Anguilla Bibroni, Kaup. 



This species greatly resembles the pimperneaux oi Cuvier; but 

 is distinguished from that eel by its narrower jaws, proportionally 

 larf^er eyes, smaller number of short conical pointed teeth, black 

 pectorals, and notably slenderer body. The character by which 

 both species may be distinguished from the remaining ones, is the 

 largeness of the eye, whose diameter is contained only once in the 

 length of the snout. 



Upper surface, dark green ; sides, silvery ; belly, yellowish. 

 Border of the anus, black. Dorsal fin, so very scanty at the com- 

 mencement that it cannot be seized or raised with the nail. Its 

 colour is that of the belly, which it preserves to the tail, where its 

 edge is darker. 



The largest specimen measures 15'54 in., whereof the tail forms 

 1004 in. The diameter of the eye is 028 in. Length, to the
