In ' British Sessile-eyed Crustacea,' vol. i. p. 67, it is stated in the 
generic description of Danaia that the mandibles are 'destitute of a palpi- 
' form appendage.' That is not so. They possess an elongate three-jointed 
palp (fig. ) which has somehow been overlooked by the author when pre- 
paring the description of the genus. The Rev. T. R. R. Stebbing in his valu- 
able work on the Challenger Arnphipoda, referring to this genus in a foot-noto 
at p. 1G71 (vol. xxix. of the Challenger Reports), points out that ' in 1849 
' Milne Edwards and J. Haime, ("Comptes Rendus," t. xxix. p. 261), gave 
1 the name Dania to a genus of fossil Corals; this name they spell 
' Danaia in the general index to their Monograph of the British Fossil 
1 Corals, Palceont Soc. vol. for 1854, published 1865. Danaia, Spence 
' Bate, must therefore give way to the later Cressa, Boeck, with which a 
1 specimen of the type species recently obtained and dissected proves it to 
' be certainly synonymous.' See also a foot-note at p. 747 of Mr Stebbing's 
work referred to above.

Habitat — From trawl refuse from Station V., Firth of Forth, February 
1892, and on one or two previous occasions from other parts of the Forth. 
This species seems to be rare in the Forth, as only one specimen at a time 
has been obtained. The Forth specimens agree very closely with the 
figures and description in the 'British Sessile-eyed Crustacea,' in having 
the Gnathopods distinctly subchelate, the rostrum strongly produced, the 
eye large and near the apex of the rostrum.

Habitat — Largo Bay, dredged 1889. One specimen only of this appar- 
ently rare amphipod was obtained. In this species the first Gnathopods 
are short and comparatively broad, and the produced part of the carpus 
terminates in a distinct finger-like process. The propodos of the second 
Gnathopods are long and slender ; the lower angle of the carpus is very 
little produced, which thus differs from other British species of Pontocrates 
that have the lower angle of the carpus of the second Gnathopods produced 
as far as, or beyond, the extremity of the propodos. In Pontocrates hap- 
locheles the lower produced part of the propodos, which forms the palm of 
the chela, consists of two distinct portions, the outer or lower is much 
more slender than the other, and terminates in a slightly curved point a 
little beyond the end of the chela. This structure, which seems to be
