5170 THE Zootocist—NoveEmBER, 1876. 
not met with it before on this coast. Its length is two inches and three- 
quarters; extreme width seven-tenths of an inch, the mantle gradually 
tapering to the fin-like membranes near the tail, which are triangular in 
shape, half an inch in width and the same in depth. The eye large and 
prominent for four-tenths of an inch in diameter; pupil black; iris yellow; 
mouth placed far back; lip oval in shape and fleshy; throat very small. 
General colour white; central under parts purely so; anterior thickly spotted 
with reddish brown; posterior more minutely so; head spotted, but not 
blotched like the back. The arms, or tentacular prolongations, misnamed 
“ feet,” are not unlike the barbels of some fishes—the rockling, for instance ; 
there are ten of them, distributed in three rows—six in the upper, two in 
the centre, and a pair beneath. The upper exterior ones, which are the 
widest, are three-quarters of an inch in length, irregularly spotted, and 
margined on the inner edge with circular whitish lobes; the second pair are 
half an inch long, spotted but not fringed; the third four-tenths of an inch, 
similarly marked, but are more slender; the middle pair measure one inch 
and seven-tenths, and have two rows of minute reddish brown spots ; the pair 
forming the lower row are three-quarters of an inch in length. Though 
Dr. Carpenter refers to the “feet” as important locomotive organs, and 
remarks that it is by them and the fin-like expansions that progress is 
chiefly accomplished, my observations lead me to believe that the arms 
are not generally used as propellers; however, the upper exterior pair, 
which are comparatively wide and lobed, may act as fins on occasions, but 
were, in this instance, drawn in and contracted like the rest, so as to appear 
like barbels fringing the mouth.— Henry Hadfield; Ventnor, Isle of Wight,
