1X6 PKOF. O. S. WEST ON TEESHWATEE EHIZOPODS. 



six longitudinal rows of widely hexagonal plates, 8 or 9 plates in 

 each row, with a short cylindrical neck at one pole ; mouth 

 circular, often witt an irregular border; plates transparent, 

 chitinoid, colourless or pale yellow ; body-protoplasm protruding 

 some three or four delicate thread-like pseudopodia. 



Length of shell 33-42 /x ; diameter of shell 21-25 /x ; diameter 

 of mouth 5-7*8 /x. 



Hah. Glenties and near Lough Machugh, Co. Donegal ; and 

 east of Eecess, Co. G-alway, Ireland. 



Living specimens of this pretty little Ehizopod were only 

 observed from Grlenties, Co. Donegal. Prom the other localities 

 only empty shells were seen, but these are unmistakable. 



It is nearest to S. macrolepis, Leidy, but is easily distinguished 

 by its larger size, smaller mouth, and by the six equal rows of 

 plates. In most ca,ses the short neck was cylindrical, but a few 

 specimens were seen in which it was slightly compressed. The 

 form of the shell and the arrangement of the plates at once 

 distinguish it from 8. lenta, Schlumbg.
