NOTES ON THE INVERTEBRATE FAUNA AND FISH-FOOD 



dium sp. ? (Stations VI. and IX.) growing on the shell. Natica monilifera 

 was taken alive on Stations I. and IV. only, but shells were common on 

 most grounds. Buccinum undatum was common only on Station VI. ; 

 Philine apcrta, common in Torbay and Station VII. of Teignmouth 

 Bay. The following were taken alive on one station only, and generally 

 in very small numbers: — Aplysia ^punctata (Station VIII. not un- 

 common), Tritonia Hoinbergii (Station VI.), Dcndronotus arhoresccns 

 (Station III.), ^olis papillosa (Station III.). 



Of the Cephalopoda, Loligo Forhesii occurred in Torbay, Teignmouth 

 Bay, and the Corner ; L. media (?) in all the bays and the Corner ; 

 Sepia q^cinalis in all the bays ; whilst S. elegans is recorded from 

 Station I. and the Corner. 



As summary to the foregoing pages, a few remarks may be made 

 on the comparative abundance of some of the common forms on the 

 various grounds in the bays, as shown in the following table : —

It is of interest to note that there is a considerable difference in the 

 size of some of the species in the different bays. Mactra solida, for ex- 

 ample, in Torbay and Teignmouth Bay is represented by small specimens
