THE ANGLER-NATURALIST. 



TEETH OF PETROMYZON OMALII. 



For a knowledge of this Lampern I am indebted to Sir 

 John Richardson, who mentions that the species was dis- 

 covered by M. P. J. Van Beneden. It is an inhabitant of 

 the British Channel, but has hitherto been taken only on 

 the Belgian coast, and by its discoverer alone. As it will 

 very probably sooner or later be found in British waters, 

 an illustration of the arrangement of its teeth (which is 

 unique) is given, together with its principal charac- 

 teristics * : Length under 6 inches. Colour silvery white. 

 Fins and external orifices like those of the Fringe-lipped 

 Lampern. Mouth circular and symmetrical. 



* From Bulletin de 1'Acad. Roy. de Belgique, 2 me serie, xi. No. 7, 

 1857.
