number of specimens, eight containing food. 



(1.) Eemains of Ophioglypha albida, and fragments of Lamellibranch shells. 

 (2.) Fragments of Lamellibranch shells. 

 (3.) A few fragments of shells, small pieces of membrane, and a large number of 



large Chaetopod bristles, Aphrodite or Hermione. 

 (4.) Small Lamellibranch shells and fragments. One of these close to the anus 



was entire, the colour unaltered and the animal undigested. 

 (5.) Small Lamellibranch shells and bristles of Aphrodite or Hermione.

Piece of Cellaria fistulosa. 



(3.) Fragments of shells. Piece of Chaetopod tube. 

 (4.) Large Chaetopod bristles, probably of Hermione.

 (6.) Large bristles, probably of Hermione. 

 (7.) Piece of Chaetopod tube. Fragments of shells.

April, 1889. Off Mount's Bay. A large number of specimens.

Malmgren. 



(3.) Cuticle of a long specimen of Lumbrinereis sp. 

 (4.) A long, much-digested specimen of a Gephyrean, Sipv.nculus (?) 



Also in several the aciculi of Hermione or Aphrodite and, in several, 

 cylindrical masses of debris containing small shells, e.g., Pecten tigrinus and 

 fragments of shells, entangled fibres, and pieces of membrane from the tubes 

 of tubicolous Chaetopoda ; also fragment of calcareous Polyzoon. 



I believe that the fragments of shells and pieces of tough membrane which occur so 

 frequently in the sole's intestines are the remains of the tubes of Thelepus circinncita, 

 Malmgren, a Chaetopod belonging to the family Terebellidae, which inhabits a mem- 

 branous tube attached by its whole length to stones or shells, and covered externally 

 with calcareous fragments of all kinds, such as fragments of shells, or entire small
