Erin Bay. When the tide receded in the afternoon a 

 layer of debris from twelve to eighteen inches in thickness, 

 and covering a considerable area of the south-eastern 

 corner of the bay, was found. This consisted of sand and 

 algae, with enormous numbers of Polychsete worms and 

 Synapta. The worms were a species of Goniada, which I 

 have not been able to determine, but which is an addition 

 to the local fauna, and NepMhys cceca of large size. The 

 Synapta is probably S. digitata. All the specimens were 

 more or less mutilated, and I am indebted to Mrs. Bailey 

 for the only tolerably perfect one found. It was one foot 

 long when handed to me. 



The harbour buoy was brought in for its annual 

 cleaning on September 16th. This year the submerged 

 bottom was almost completely covered with Tunicates, of 

 which Ascidia mentula and Ciona intestinalis were the 

 most abundant species. There were also several excep- 

 tionally fine colonies of Didemnum sp., and a single 

 specimen of Ascididla venosa. The Amphipods, Podo- 

 cerus falcatus and Protella phasma, abounded, as usual, on 

 the numerous colonies of Scrupocellaria, and, as was the 

 case last year, there were three examples of the variety 

 pellucida of Mytilus edulis. The buoy also provides the 

 only habitat known to me in this part of our district for 

 Sabella pavonia. This beautiful worm occurs every year, 

 and it is rather singular that I have never found it on the 

 beach at low tide, its usual habitat on the coast of North 

 Wales. 



Amongst the numerous additions to our collection of 

 living animals in the aquarium tanks made during the 

 cruise of the s.s. " John Fell," on April 18th, was a 

 specimen of the hermit crab, Eupagurus prideauxii, with 

 its commensal anemone, Adamsia palliata. These two 

 interesting partners lived until September, when, during
