528 APPENDIX. 
CDICEROS PARVIMANUS. 
(Vol. I. p. 161.) 
Some specimens have been sent to us from the Shetlands 
by Mr. Gwynn Jeffreys, and from Banff, where they were taken 
by Mr. Edward, that so nearly correspond with this species, 
that we think they must be the male form. They differ from 
that described in having the upper antennee but little longer 
than the peduncle of the lower; the lower antennz as long 
as the entire animal; and the gnathopoda with hands some- 
what larger, but scarcely equal to the “very large” hands as 
described by Kroyer in his description of the genus. 
KROYERA ARENARIA. 
(Vol. I. p. 173.) 
A specimen of Kroyera has been sent to us by Mr. Robert- 
son, who found it in sand near low water in Kames Bay, 
Milport. It differs from K. arenaria in having the inferior 
antennee longer than the animal. 
It may, as Mr. Robertson suggests, be the male. 
ACANTHONOTUS OWENII. 
(Vol. I. p. 232.) 
We have no hesitation in referring this species to the Gam- 
marus corniger of Fabricius,* whose specific name has long 
priority over any of the other names quoted in the page 
above referred to, and must consequently be adopted instead 
of that employed by us. It is also identical with the Epimeria 
tricristata of Signor A. Costa (Mem. di Real. Accad. Sci. 
Napoli, i. tab. 2, f. 2, 1853). 

ATYLUS GIBBOSUS. 
(Vol. I. p. 248.) 
Specimens of this species have been sent to us by Mr. 
Robertson, who took them on three different occasions in 
Kames Bay, imbedded in sponge on the valves of Pecten oper- 
* Tter Norwag. d. 20 Aug.; Spec. Ins. i. p. 517 (1781) ; Mant. Ins. i. 
p. 334 (1787) ; Ent. Syst. ii. p. 517 (1798).
