either wholly or in part follicular. These bodies are small, elon- 

 gate, for the most part round in section, seldom flat. Prof. v. Graff 

 divides the Rhabdoccelida into three tribes : — 



Digestive tract and parenchyma-tissue not differentiated ; nervous 

 system and excretory organs absent. 1. Acoela, with five genera. 



Digestive tract and parenchyma-tissue differentiated ; nervous 

 system and excretory organs present. 



2. lihabdocoela. — Body-cavity usually spacious, with little paren- 

 chyma-tissue, by which the simple stomach is suspended. Genital 

 glands separated from the body-parenchyma by a special tunica pro- 

 pria. Twenty-six genera. 



3. Alloiocoela. — Body-cavity small, in consequence of the large 

 development of the parenchyma-tissue ; genital glands scarcely ever 

 possessing a special tunica propria. Eight genera.

Note on the Occurrence of Ommatostrephes sagittatus, Lam., at 



Eastbourne. 



Gentlemt^, — There has been lately found on our shorea specimen of 

 one of the rarest of the Cephalopoda, the occurrence of which is worth 

 a notice in your Journal. This is the Ommatostrephes sagittatus, 

 Lam., the flying squid of the fishermen. The species is considered 

 a deep-sea form, and probably only approaches the land in order to 

 deposit its eggs. A specimen is recorded to have been taken off 

 Brighton by the Dowager Marchioness of Hastings, and another by 

 Mr. Mackie at Folkestone, by Forbes and Hanley, in * British Mol- 

 lusca/ vol. iv. p. 231 ; and to these localities Mr. J. Gwyn Jeffreys, 

 in ' British Conchology,' vol. v. p. 129, adds Falmouth, Polperro, an 1 

 Guernsey. The specimen found here was taken alive in a rock- 

 pool off the Parade at Eastbourne, and brought up to a fishmonger 

 in the town ; it was nearly 15 inches long, which is about the size 

 noticed by Messrs. Forbes and Hanley, in whose work there is a 



very good figure.

deletii, Loligo vulgaris, and L. media have previously been taken 

 on our shore ; and the occurrence of the Ommatostrephes is a very in- 

 teresting addition to our local fauna.
