Gegenhauri has also a resemblance to this species, but its teeth 

 are scarcely visible, and its anus is in the middle of the body.

13. Leptocephalus stenops, Kaup. 



Diagn. Stout teeth, and large approximating eyes. 



Descr. This species may be at once known by the position of the 

 eyes near to each other, their blackness, and their unwonted size. 

 On the jaw, beneath the eye, there are about twenty-one fine teeth, 

 which are difficult to number ; three or four bigger ones exist farther 

 forwards, but I have been unable to detect any on the point of the 

 snout. On the mandible there are about seventeen. On the border 

 of the belly there are some ring-shaped, pigmentary spots. The 

 anus is placed moderately far back. Along the anal fin, a row of 

 fine points. Rays may, by the aid of a lens, be distinctly seen in 

 the small caudal fin. 



Total length 4-.53 in.

An example exists in the Paris Museum, probably, but not 

 certainly, from Messina. 



14. Leptocephalus longirostrts, Kaup, fig. 14. 



Diagn. Length of the diameter of the eye contained nearly 

 twice in the length of the snout. Tail pointed. 



Descr. This species was also discovered by Bibron at Messina, 

 and is distinguished from its congenei's by the length of its snout. 

 The teeth are distinctly visible, and stand on the outer border of 

 the transparent jaws : they are pointed, and inclined forwards. 

 The front ones of the upper jaw are almost horizontal, and the 

 opposing mandibular ones are curved, and somewhat card-like. 

 Eight teeth, of a smaller size than those nearer the point of the 

 snout, stand under the eye. On the mandible there are seventeen, 

 of which the smaller ones are near the comer of the mouth. Body 

 unusually high, and towards the tail flat and tapering. In the 

 solitary specimen contained in the Paris Museum, I saw no points, 

 nor was I able to discover the position of the anus. The large eyes 

 are black, and a dark tint intervenes between them and the point 

 of the snout. Opercula and pectoral fins distinctly visible, but the 

 rays of the pectoi'als are not distinguishable. 



15. Leptocephalus brevieostris, Kaup, fig. 15. 



Diagn. Fourteen teeth in the upper jaw, and as many on the 

 mandible, the smallest being the upper ones near the corner of 

 the mouth. Neither on the lateral line, nor elsewhere, are rows 

 of dots to be seen.
