Family TRICHONISCIDAE. 



Trichoniscus Brandt. 

 Subgenus Trichoniscus, s. str. 

 Trichoniscus (Trichoniscus) demivirgo Blake. 



I have no records to add to the distribution of this species 

 (Blake 1931, p. 343). It occurs near the coast from Mount 

 Desert Island, Me. to Nantucket, Mass. 



MiKTONiscus Kesselydk. 

 Miktoniscus halophilus Blake. 



To the distribution (Blake 1931, p. 347) of this species also I 

 have nothing to add. It appears to be distinctly southern and 

 may eventually be found on the salt marshes of Rhode Island and 

 Connecticut. 



CoRDiONiscus Grave. 

 Cordioniscus stebbingi (Patience). 



Trichoniscus stebbingi Patience (1907, p. 42). 



This species, which is new to the New England fauna, I have 

 only from a hothouse in Cambridge, Mass. It occurs under pots 

 where it is both wet and muddy. 



Family SCYPHACIDAE. 



ScYPriACELLA S. I. Smith. 



Scyphacella arenicola S. I. Smith. 



This species has been reported within New England only from 

 Woods Hole and Nantucket, Mass. (Harger 1880, p. 308). It 

 may be found eventually on many sand beaches from Monomoy 

 Island west. 



Armadilloniscus Uljanin. 

 Armadilloniscus ellipticus (Harger). 



I have already reported (1930, p. 281) on the distribution of 

 this animal. 



Family ONISCIDAE. 



Oniscus Linne. 

 Oniscus asellus Linne. 

 Previous records. — Me.: Freeport (Rathbun 1905, p. 45).
