Johnston's diagnosis of the species is as follows : — " Body cylin- 

 drical, smooth, striped; tentaeula twelve, uniserial, sub-marginal, 

 annulated with brown." He quotes the following from Peach's 

 ms. : — " This Actinia I find under stones buried in sand in Fowey 

 Harbour between the tide-marks. Body pale, nearly white, with 

 six broad stripes, and three narrower ones between each of the two 

 broader ones, the centre one of the three the broadest — all running 

 the whole length of the body, but are nearly lost before reaching 

 the lower end : these stripes are again divided by transverse nar- 

 row ones. The tentaeula are invariably twelve ; the mouth is in 

 the centre, and surrounded by brown flower-like markings. It 

 does not attach itself, but lies buried in sand, with its head 

 just above." 



" The species readily assumes various shapes, as shown in the 

 figures of it. It is quick in its motions, and buries itself in the 

 sand when disturbed." 



Cocks merely quotes an abbreviation from Peach's diagnosis, 

 and adds : — " In pools with sandy bottoms, Grwyllyn-vase, Pen- 

 nance, &c. ; not uncommon." His figures are very unsatisfactory ; 

 in both only eleven tentacles are represented, although the text says 

 "tentaeula twelve"; in fig. 20 they are banded, but not so in 

 fig. 21 ; in both the disc is quite plain. In fig. 20 the animal is
