Shell with eight valves, nearly smooth, ridged down the 
back and beaked, finely fringed round the margin, a little 
reflected on the hinder angle at the base : color grey or 
with a reddish tinge: length a quarter of ail inch. 
Jt differs from the last principally in the margin, which 
r is not reticulate, but furnished with a fine fringe* Hi 
color is also of an uniform grey with occasionally a Jaiit 
'reddish tinge. The color of the Ch. Ice vis is ofadri 
•dusky red, which does not change after it is dead, as is tri¬ 
dent from the specimens in our o wn cabinet* which hart 
been preserved for some years. Mr. Dilhvyn, howerer, 
has united the two species into one, under the assertion 
that the Ch. lzjcvis is red when alive, and grey when dead.

Shell with eight valves, raised, beaked, and margined,. 
'very convex, deep red, finely and distinctly punctured ill 
over. The valves being distinctly punctured in this spt- 
cies seem to mark the only difference between it and tit 
Cfi. Iffivis, in which they are faintly but evidently stride 
''only : size of the last. 
It is probable that the Chiton ruber, so very slightly 
mentioned by Laskey in the Memoirs of the Wernerian 
Society, as being transversely striate, is only the Ch.keA 
' of a deeper color.
