While we have no Maine record for this species, there is no 

 reason why it should not be found on our shores, especially since 

 bisuturalis and trifida have been reported from rivers in Lincoln 

 and Cumberland counties. Stimpson gives the range of trifida, 

 "Buzzard's Bay to New York" and of bisuturalis, "Mass. Bay;" 

 while of seminuda, he gives the range as from "Mass. Bay, 

 northward."
