on the deep-sea lines. The Holothuria 

 montaguii, founded by Dr Fleming on a 

 specimen obtained in the Forth by Dr 

 Neill, was probably this species. 



Cucumaria lactea (Forb. and Goods.). 



Off Fife coast (J. .) ; Firth of Forth 

 (M'R) ; Firth of Forth, 22 fathoms 

 (M. & R). 



This is one of the commoner species near 

 the mouth of the Firth. Mr D'Arcy 

 Thompson informs us that he has obtained 

 several specimens. 



Thyonidium commune (Forb. and Goods.). 



East coast of Fife (J. #.). 

 The Cucumaria communis of Forbes. We 

 obtained one specimen from the stomach 

 of a cod. 



Thyonefusus (Mull.). 



Anstruther (J. #.) ; Firth of Forth (Com. 

 Mar. ZooL). 



The Thyone papillosa of Forbes. Mr F. 

 M. Balfour informs us that he has taken 

 this species at 12 to 16 fathoms on mud 

 and shells off North Berwick. 



SYNAPTID.E. 



Synapta inhcerens (Miill.). 



Bass Eock, 24 fathoms (M. & R). 

 Mr F. M. Balfour has found this species 

 under stones, between tide marks, at the 

 mouth of the Tyne, near Dunbar. 



In addition to these, two species are described by Dr 

 Fleming in his "History of British Animals," under the 

 names of HolotJiuria dissimilis = Cucumaria dissimilis, 

 Forbes (Leith shore, Colds.), and Holothuria neillii = Cucu- 

 maria neillii, Forbes (Firth of Forth, Dr Neill).
