Dimensions. 



One inch to two inches in height, and sometimes reaching an 

 inch and a-half in the diameter of the column. 



We are indebted to the kindness of Miss James, of Babba- 

 combe, for eleven specimens of this scarce and interesting anemone. 

 They were procured at the Ore Stone, near Torquay, from between 

 tide-marks. This is a new locality for this species, which was 

 previously known as occurring only at Lidstep and Ilfracombe, 

 both in the Bristol Channel. 



The description given above of the form of this anemone has 

 been based on Gosse's description, but certain changes have been 

 introduced so as to make it apply to those specimens which we 

 have examined. The description of the colour is based on these 

 latter specimens alone. They were identically the same in this 

 respect with each other, but did not correspond with any of Gosse's 

 varieties. The points in which we have differed with Gosse in 

 describing the form, are — (1) the number and arrangement of the 

 warts, and (2) the number of the tentacles. 



First, then, as to the number of warts : — 



Gosse, in his earliest account of the anemone (Ann. and Mag. 

 Nat. Hist., ser. 2, vol. xiv., p. 283 : Tenby, pp. 361-363), says there 

 are twenty-five to thirty longitudinal rows of warts, and about 

 twenty- five warts to each row. In the account subsequently given 

 in his monograph (Actin. Brit. p. 195) the same author gives the 

 number of rows as about thirty-six, and the number of warts in 

 each row as about twenty-five. We have thought it better to state 

 the number as indefinite : it evidently depends on the size of the 

 specimen, and in those we examined the largest number of rows 

 we found was forty, and the smallest sixteen ; the number of warts 

 in each row varies also with the size of the animal. There is no 

 doubt that the warts are developed in the alternate spaces between 

 the lines marking the insertions of the mesenteries, that is, in the 

 endocoeles, as we shall see presently. Gosse also states that the 

 margin is " serrated with the elongated topmost warts of all the 

 rows." We did not find this to be invariably the case ; in some 

 specimens (and these were the larger ones) the topmost wart of 

 only every alternate row rose above the parapet.
