off the coast of the Isle of Man. 435 



Echinus sphara. Common. 



miliaris. Common. 



lividus. Common. 



Spatangus purpureus. Common off Laxey and Maughold Head. 

 Amphidotus cordatm. Common on the shore at Ramsey, but 

 «3nly one broken specimen was dredged off Maughold Head. 



The following is a list of the Annelidse, only a few of which I 

 was able to name, for want of a good work on the subject ; I have 

 however preserved in spirits a large number taken both off the 

 Isle of Man and on the Welsh coast, which I shall be happy to 

 place in the hands of any brother-naturalist who is better ac- 

 quainted with them than I am. Many notes and drawings were 

 made of those collected. 



Nereis bilineatus. On shore near Douglas. 



Aphrodite aculeata. Dredged off Laxey. 



Cirratulus medusa. On the shore near Derby Castle. 



Arenicola piscatorum. Common. 



Many of the common species of Zoophytes abounded. The 

 following is a list of those which I have not found in great 

 abundance on the Welsh coast, and some not at all : — 



Anthea cereas. Douglas Bay, on rocks. 



Tuedia. Douglas Bay, on rocks. 



Actinea maculata. Dredged off Maughold Head and Douglas 

 Head : not common. 



Coryne squamata. Douglas Bay, on rocks. 



Tubularia indivisa. On rocks round the Calf of Man at low 

 spring-tide-mark, in abundance ; it was among this coralline, 

 having filled several cans with it, that I found three specimens 

 of Acheus Cranchii, a Dendronotus, and a Tritonia which I have 

 been unable at present to name. The former was found on 

 pulling the clusters to pieces, the two latter crawling on the 

 stems. 



Sertularia pinnata. Taken round the Calf on sea-weed at low 

 spring-tide water-mark. 



Laomedia geniculata. On sea-weed round the Calf. 



Campanularia syringa. Douglas Bay. 



Cydonium Mulleri. Dredged off Douglas Head. 



Cellipora pumicosa. On other species of coralline in Douglas 

 Bay and on the Calf. 



Flustra membranacea. Common. 



I have also been able to identify the following Sponges : — 

 Halichondria Johnstonii. In caves below spring-tide low water- 

 mark, under Black Head.
