 Tlie distance between the tip of the snout and the pectoral is com- 

 prised nearly twice in that between the pectoral and dorsal. Near 

 the corner of the mouth the palatine plates of teeth run out to a 

 point, and the nasals and vomerines form a broad abbreviated plate, 

 rounded off behind. Lips very wide.

 from the darkness of the transverse- and oblique-lying scales.

98. Angdilla Delalandi, fig. 41. 



Anguilla Delalandi, KaujJ. 



Delalande caught this remarkable eel in the Great Fish Paver of 

 the Cape of Good Hope, and sent it to the Jardin des Plantes, In 

 the size of the jaws and fashion of the dentition, it resembles greatly 

 viegastoma (No. 99); though its nasal teethoccupy a little less breadth, 

 and those of the vomer do not contract so much into a narrow 

 stalk-like prolongation. As in the A. Aucklandi (No. 92), the eye 

 is situated before the corner of the mouth ; but the dorsal fin 

 reaches farther forward than in that species. 



Total length, 37'03 in. Length of tail, 18-10 in. To the pec- 

 toral, 1-81 in. To the dorsal, 12-81 in. To the corner of the 

 mouth, 1-73 in. To the eye, 1-22 in. Length of the pectoral, 

 1-89 in. 



Mursena macrocephala, Rapp, Wurzhurgische Jahreshefte, iv., p. 

 142 (Port Natal), may be cited doubtfully as a synonym of this 

 species. It is at least a genuine eel, and nearly related to Dela- 

 landi.
