apply to males and females, adults and juveniles. The legs 
of the first pair were wanting in.all Mr. Spence Bate’s speci- 
mens. ‘These are very small and delicate, and, both in living 
and dead specimens, are cuddled up within the coxe, as if they 
were too tender and precious for use. The wrist is long, and 
at its distal end as broad as the hand. The hand is nearly as 
broad as it is long, diminishing towards the finger, which is 
short and curved. ‘The legs of the second pair are beautiful 
objects under a good lens or microscope. The wrist is larger 
than the hand, but of the same shape. Both are adorned with 
long plumose hairs; and the hand is fingerless. ‘There is an 
awkwardness in speaking of hand and wrist as portions of a 
lez; but one is happy to escape when possible from the repeti- 
tion of terms like the propodos of a gnathopodos or the ischium 
of a pereiopodos, and there is a convenience in using accepted 
and easily intelligible terms which will atone for some linguis- 
tic improprieties. We proceed, then, to notice that the hands 
of the third and fourth pairs of legs are long and thin, and 
have fingers attached to them. These would appear to be 
very serviceable limbs, to judge by the activity of their move- 
ments, and also by the position to which they aspire ; for they 
are constantly thrust forward in advance of the graceful but 
comparatively inactive second pair of legs; and this forward 
position they maintain with some obstinacy, even when the 
animal that owns them is dead. 
The three following pairs of legs, like the second pair, are 
destitute of fingers. They are very actively employed in 
shovelling back the sand when the animal is burrowing into 
it. In the quiescent state, and after death, the lower joints of 
the fifth pair are cocked back, and the lower joints of the 
seventh pair are thrust forward, to such an extent that the 
three final couples seem almost to have their order of position 
exactly reversed. The fifth pair has the most curious appear- 
ance, because the hand and wrist are so slight and spindle- 
shanked compared with the well-developed joint to which they 
form an appendage. In this pair the wrist is longer than the 
hand. In the two following these proportions are reversed. 
Mr. Spence Bate assigns a long slender finger to the hand of 
the fifth pair in B. pilosa. As there is no finger at all to this 
pair in either of his other species, so unusual a difference be- 
tween species of the same genus would be remarkable ; but as 
my Welsh specimens have none of them any vestige of this 
finger, it must be concluded that in Mr. Bate’s imperfect spe- 
cimen the hairs at the extremity of the hand had assumed, as 
they well might do, the appearance of a finger. It may be 
remarked that the drawing of the finger in the ‘ British Ses-
