Leith Shore (E. J.) ; Firth of Forth (M'B). 

 We have dredged this species frequently

PEDICELLINIM. 

 Pedicellina cernua (Pallas). 



Firth of Forth (M'R). 

 This species, the Pedicellina echinata of 

 Johnston and others, is not uncommon in 

 the Firth. We have taken both the echin- 

 ated and the smooth (P. belgica, Gosse) 

 variety. It occurs in profusion on the tests 

 of Styela grossularia under large stones at 

 Newhaven.
