64. CAPRELLID ®. 
female (figured above) they articulate quite at the ante- 
rior extremity. This is the only reliable distinction that 
we have been able to discover between the two sexes. 
The hand in this pair of legs is ovate, the palm convex, 
being defined by a process surmounted by a spine. The 
palm is emarginate near the posterior extremity, and 
waved a little anteriorly. 
We consider this species to be identical with that 
figured by M. Milne Edwards in the place cited, as also, 
probably, with the C. Hystriz of Kréyer, although the 
description of the head given by the former author, 
** ovalaire, courte et arrondie en dessus,’’ seems to have 
been derived from C. acanthifera, and his observation that 
the penultimate joint of the last three pairs of legs is 
narrow and without a tooth on the inner edge, disagrees 
with our species (although agreeing with Kréyer’s details 
of the legs of C. hystrix). Unfortunately M. Milne 
Kdwards is unable to clear up this difficulty, the speci- 
men from which he drew his figure not having been 
preserved. 
Considering the C.acuminifera of Latreille to be identical 
with C. acanthifera of Leach, we have been obliged to 
take up Kidyer’s name for the present animal, although 
not quite agreeing with his description as above noticed. 
We have received specimens of this species from 
Millport, sent to us by Mr. Robertson; from Northum- 
berland, where it was found by the Rev. A. M. Norman, 
and we have taken it in the neighbourhood of Ply- 
mouth.
