238 CHAS. L. WALTON. 



greatly resembled the olive-coloured algte growing in the pools. All 

 these specimens were normally coloured, the chief variation being 

 the warts. In those individuals which lived affixed beneath stones 

 the warts were frequently by no means strongly developed, and the 

 whole column lighter in colour (in one instance dirty white). Those 

 living exposed in the shallow pools possessed very conspicuous warts, 

 especially toward the summit, where they were crowded, prominent, 

 or even somewhat clavate. 



An isolated colony of about a dozen specimens was discovered 

 in Port Quin Bay, nearer Port Isaac. They were of the variety 

 described by G. Y. and A. F. Dixon, from Torquay. Living in a 

 long crack between two bare, rounded rocks in a pool about half-way 

 up the reef, their opaque white tentacles (which are also slightly 

 longer and more tapering in this variety) gave them the appearance 

 of a colony of some species of Sagartia. The pattern of the disk 

 showed some variation, but in most cases the raying was obscure, dull 

 grey and umber predominating. The rays were more pronounced in 

 the younger examples. 



III. The Actinian Fauna of Salcombe. 



Allen and Todd (3) enumerated eight species as found in the estuary. 

 During a recent visit I examined the reefs on either side of the 

 harbour mouth, with the result that six further species were discovered. 

 This is partly owing to the fact that I collected rather further seaward 

 than Allen and Todd, although several occurred within the area they 

 examined. 



The following are the additional species : — 



1. Sagartia miniata. Eocks between South Sands and Splat Cove, a 

 few specimens. 



2. >S'. nima. Pieefs near Mill Bay, a few. Molt Point, one specimen. 



3. S. sphyrodeta. Between South Sands and Splat Cove, a few. 



4. S. pallida. Splat Cove, two on the under side of a stone in a 

 pool on the reef. Normal size. 



5. Bunodes verrucosa. Molt Point, a few. Mill Bay, not uncommon. 



6. Corynadis viridis. Very abundant in sheltered positions on the 

 reefs between Mill Bay and the Blackstone. 



IV. Actiniae collected between Bolt Tail and the River Avon, 



South Devon. 



The following observations were made ditring January and February, 

 1910. The species obtained were all littoral. The examination of 

 the coast was as thorough as the weather would permit, but many days
