Length of head 3f to 3g in the distance between the snout and the vent : length of tail 1/4 to 1/6 more 

 than that of the trunk. Eye — rather varies in size, usually about 2i diameters in the length of the snout. 

 Head very slightlj- broader than the body : snout rather broad : lower jaw scarcely longer than the upper. 

 Extent of cleft of mouth equal to rather above 1/3 of the length of the head, and extending to at least 1 

 diameter of the orbit behind the eye in the adult, to below it in the immature. Tjips tliick. Teeth — bands 

 of nearly equal width, the vomerine reaching nearly as far backwards as those on the maxilla. Fins — dorsal 

 commences above the vent or slightly before or behind it. Colours — oi a dark olive superiorly, becoming 

 yellowish beneath. 



Dr. Giinther observes that Anguilla virescens, Peters, from the West Coast of Africa is scarcely distinct 

 from A. sidat, Bleeker.
