drawn in a vertical position, its base being expanded and attached 

 to a stone ; although it can stand upright in the water when in con- 

 tact with a hard substance, it does so owing to the tenacity of the 

 suckers of its physa, and not, so far as I am aware, in consequence 

 of the latter forming a basal disc. Fig. 21 merely gives a fore- 

 shortened view of the disc and tentacles, and below it is an indis- 

 tinct figure which is not referred to, and which apparently is 

 intended to represent the aspect of the tentacles, &c, when buried 

 in the sand. I mention this Paper and figures in detail to obviate 

 the necessity of future reference, as the Annual Report in which it 

 occurs is not easily accessible. 



Gosse, in his Paper in the Transactions of the Linnean Society, 

 1855, adds no new facts ; he speaks of its " sensitiveness to alarm, 

 and the spring-like rapidity of its motions." He considered that 

 there was a posterior aperture. Size, " very minute." In his 

 Marine Zoology, 1855, and in his Synopsis of the British Actinias, 

 1858, Gosse merely alludes to the species ; in the latter, he cor- 

 rectly constituted it the type of a new genus, to which he gave 

 the name Halcampa. 



In his Monograph, 1860, Gosse mentions that he had upwards 

 of a dozen specimens sent him, in 1858, from Fowey. As these 

 came from Peach's locality, their identity with the discover's spe- 

 cies is beyond doubt, but the marking seems to be quite different 

 from the original figure (I. c. pi. xxxvu., fig. 13). The latter, how- 

 ever, is very unsatisfactory. Gosse's description of the markings of 

 the disc, also, does not particularly well agree with the woodcut he 

 gives. The description is as follows : — 



Column. — " Drab or dirty white ; septa as white longitudinal 

 lines ; the swollen bladder-like extremity translucent. 



Disk. — " Marked with a pretty star-like pattern, consisting of 

 a pale-blue area inclosed in a pale line, and surrounded by twelve 

 triangular rays of a dark-brown hue ; each triangle surmounted by 

 a pale, W-like figure, which incloses a dark-brown area, according 

 to the accompanying pattern. 



Tentacles. — " Pellucid brown, the front crossed by six semi-rings 

 of opaque white, of which the second, the fourth, and the fifth 

 (counting from the foot upward) are angular, the second pointing 

 downward, the fourth and fifth upward. . . . The pellucid inter- 

 spaces are tinged with brown, deepest on the first, second, and
