XXXIX. — On some new Protozoic Annulafa. By Frederick 

 M'CoY, Professor of Geology and Mineralogy in Queen's Col- 

 lege, Belfast. 



Myrianites tenuis (M'Coy). 



Sp. Char. Usually coiled in numerous, small, very irregular un- 

 dulations ; diameter of body about one-third of a line. 



This beautiful little worm is easily distinguished from the 

 M. Macleaiji (Murch.) by its very slender proportions, agreeing 

 more nearly in this respect with the M. Murchisoni of Prof. Em- 

 mons's " Taconic Slate.'' 1 think it was about a foot long, from 

 following, as well as I could, the convolutions of throe indivi- 

 duals. I have only in one part seen traces of the cirrhi, which 

 have the same general proportions as in the M. Macleayif^lwich..) . 

 Not uncommon in a particular layer of the fine olive slate of 

 Greiston, on the Tweed, near Inverleithcn. '•'•' /J"-'"" *' t'"^'
