THE MOUNT DESERT REGION 241 



Paradoxostomatinae 

 ScLEROCHiLus 6. 0. Sars 

 S. coNTORTUs (Norman). (G. 0. Sars, 1928, p. 247, pi. 112.) 

 Miiller's (1912, pp. 260-261) key to this genus fails for 

 S. contortus, since the Norwegian specimens attain a length 

 of 0.8 mm. and the New England specimens 0.71 mm. This 

 species is found with algae and Bryozoa, from the shore to 

 90 feet. Stations: D 29, 35, 104; S 4, 43.
