 has also recorded it from New Gtrimsby Harbour, Scilly 

 Islands.

Rock-pools at and above high-water mark, Plymouth, 

 August 22nd, 1903 ; rather rare. We regard the Thalestris 

 forficuloides described in 1894 by T. & A. Scott, from speci- 

 mens obtained in the Firth of Forth, as identical with Clauses 

 species. M. forficula, though apparently widely distributed, 

 does not seem to be anywhere very common.
