segments of the pereion, Lad lost all trace of segmentation, the posterior portion 
of the body being very slender and much narrower than the segmented anterior 
portion. There were two specimens of a Galathea, which seems to me to be 
identical with a form first taken between Marion and Crozet Islands at a similar 
depth. There were several specimens of a Crangon, which is apparently not scarce 
in great depths, having been met with on two previous occasions, and two species of 
Peneid shrimps, which have been taken often since leaving St. Thomas. One of the 
Xymphonids had a Campanularian on its legs. An Amphipod, resembling in appearance 
Kroyer’s genus Unciola, but distinguished by the absence of legs on the sixth, and of all 
appendages on the seventh, segments of the pereion, was taken ; it had breeding lamellse 
on the second to the fifth pairs of legs, and branchiae on the third to the sixth pairs.” 
Foraminifera (Brady, Zool. pt. 22). — The following species of Foraminifera were 
observed in the deposit from this Station (see also Murray and Renard, Deep-Sea 
Deposits Chall. Exp.) ; the pelagic species, which make up about 47 per cent, of the 
carbonate of lime present in the deposit, are marked thus x : —
