Genns Lerneonema. 

 L. moniUaris, Edw. 



This species has been favoured me by Dr. Ball, who procured speci- 

 mens adhering to the sprat {Clupcu Sprattus) at Youghal. Dr. Ball re- 

 marks that when alive it is of a beautiful green colour, and generally ad- 

 heres to the cornea of the fish's eye : one of those sent to me is fixed to 

 the body of the sprat close to the dorsal fin.

The first specimen of this Nipnphon which I have seen was taken by 

 Dr. J. L. Drummond at Macedon Point, Belfast Bay, upwards of twenty 

 years ago. From 1834 to the present time I have occasionally procured 

 it on the North-East coast.

Examples of this species have been taken in Belfast Bay, &c.

Dredged from eight to ten fathoms at Donaghadee in May, 1843, by

 who notes it however as inhabiting " La Manche."
