MARINE ZOOLOGY OF ARRAN. 275 



Arran, the subjoined tables may advantageously be added 

 for the information of naturalists not practically acquainted 

 with the Fauna of the Clyde. The species marked with an 

 asterisk were dredged by the late Rev. Dr. Landsborough and 

 Major Martin; and the other species were obtained by Dr. 

 Greville and myself, in our examination of this part of the 

 coast. The list, so far as completed without the assistance of 

 the former gentlemen, appears in the "Annual Report of the 

 British Association for the Advancement of Science for the 

 year 1856." Dr. Landsborough and Major Martin were inde- 

 fatigable in their investigation of these localities. There yet 

 remains, however, much work to be accomplished by future 

 inquirers especially among some of the remarkable groups, 

 as the Cirripeda Annelida, Acalepha, Zoophyta, and 

 Poriphora as also among the Polyzoa and microscopic 

 forms included in the Infusiora and Rhizopoda.

120. I am not able to add anything to Dr. Miles' list except 

 on one point, which is a very curious one. There are two species 

 of Comatula (Art. 109) in Lamlash Bay; one of them, the 

 commonest, being that described by Edward Forbes as 

 Comatula rosacea; whilst the other, rare there, but tJte 

 species, of the south of England, is that described by Miller 

 in his " Crinoidea," and designated by Miiller, Comatula 

 Milleri. I have reason to think that the latter not the 

 former, as believed by Edward Forbes is identical with the 

 Comatula Mediterranea of Lamarck. But this I cannot take 

 upon myself certainly to say, until I have had a specimen of 

 the C. Mediterranea for careful examination. Putting aside 

 other differences, the distinction between the two species of 

 Lamlash Bay is well marked by the presence in C. Milleri of 

 what Miller has described and figured as a single inter-radial 

 plate in each of the angles between the origin of the rays,
