rather large ; the seven lateral openings ranged in a line 

 behind, but a little obliquely and below it, on each side : the 

 lip surrounding the mouth has a continuous row of small points 

 on its margin ; the mouth and teeth as represented near the 

 figure of the fish : the back furnished with two rather elongated 

 dorsal fins, with a separation between them ; the tail furnished 

 with an extension of the membrane above and below. 



The skin is quite smooth, of a blue colour on the back and 

 sides, passing into silvery white underneath. 



In " The Treatyse of Fysshynge wyth an Angle," attri- 

 buted to Dame Juliana Berners, and first printed by Wyn- 

 kyn de Worde, in his edition of the Book of St. Albans, in 

 1496, the learned lady, after recommending a minnow and a 

 worm as proper baits for the Trout in the month of March, 

 adds, " In Aprill take the same baytes : and also Juneba, 

 other wyse named VII. eyes."" 



Seven eyes and nine eyes, in reference to the apertures 

 about the head, are common names for the Lamprey in this 

 and some other countries ; but a derivation for the term 

 Juneba is a desideratum. 



Linnseus, in his Tour in Lapland, particularly notices this 

 species, vol. ii. p. 196, as found in West Bothnia, and de- 

 scribes the modes by which they are caught, namely, hollow 

 cylinders of wood, and elongated wicker-baskets, like those in 

 use in this country for catching Eels. These, he says, " are 

 laid at the depth of two ells in the river, and kept down with 

 stones, the opening being turned to meet the current." 



This species is also said to be found at Moscow, and in the 

 Black and the Caspian Seas.
