70. Anguilla makginata, fig. 20. 

 Anguilla marginata, Kaiip. 



In the Paris collection there is a small eel from Valentia, iu 

 Spain ; but whether it is a marine or fresh-water species, or what 

 period of its growth it has reached, I did not ascertain. The 

 vomerine teeth extend no further than to opposite the eye. The 

 eye is of medium size, and its diameter is contained once and a 

 half in the length of the snout. Black dots are sprinkled on the 

 inner side of the moderately-developed lips. The distance from 

 the tip of the snout to the pectoral goes once and two-liflhs iu that 

 between the pectoral and the dorsal. 



Dorsal surface, greenish, dotted with black ; ventral aspect, sil- 

 very white. Dorsal, whitish, with dark points and a darker bor- 

 der. Pectoral, whitish on the outer side, with dots at the tip, and 

 dotted throughout on the side next the body. Anal, whitish ; 

 darker towards its extremity, with dots, and edged like the dorsal. 

 Pores of the lateral line conspicuous only near the pectoral. 



Total length, 9-45 in. Length of tail, 5-51 in. To the corner of 

 the mouth, 32 in. To the pectoral, 1-18 in. Distance between 

 the pectoral and the dorsal, I'Oo iu. Length of pectoral, 0-39 in. 



71? Anguilla microptera, fig. 21. 



Anguilla microptera, Kaup. 



This small eel, which I was inclined to consider as the same 

 with the preceding species, was taken in the Bay of Algesiras, and 

 brought by the "Astrolabe" to Paris. The pupil of the eye and 

 the corner of the mouth are in the same vertical line ; and the dia- 

 meter of the eye is contained once and a half in the length of the 

 snout. Pectoral tin and mandible equal to each other in length. 

 The distance between the end of the snout and the pectoral goes 

 once and two-fifths in the length of the space between the pectoral 

 and the dorsal. It is iu some degree different from marginata (No. 

 70) by the extent of the vomerine teeth. 



Colour, bright olive-green, with innumerable points on the 

 transverse and oblique-lying scales. Ventral surface, smutty 

 white. 



Total length, 11-81 in. Length of tail, 670 in. To the eye. 

 0-28 in. To the corner of the mouth, 039 in. To the dorsal, 

 3-55 iu. Length of the pectoral, 041 iu. Length of gape, 0-41 in.
