90 THE DEPTHS OF THE SEA. [CHAP. III. 
trip would require a clear fortnight, as much coal 
was stacked on deck as was considered prudent. 
This cruise was entirely successful. The weather 
was remarkably fine, and Mr. Gwyn Jeffreys’ party 
found it possible to work the dredge during seven 
days at depths exceeding 1,200 fathoms, and on four 
days at less depths. The greatest depth achieved was 
1,476 fathoms (Station 21), and this dredging yielded 
mollusea, a stalked-eyed crustacean with unusually 
large eyes, and a fine specimen of Holothuria tremula. 
The deep dredgings in this trip yielded an abund- 
ance of novel and most interesting results in every 
sub-kingdom of the invertebrates. Among the mol- 
lusea were valves of an imperforate brachiopod, with 
a septum in the lower valve, which Mr. Jeffreys 
proposes to name Afretia gnomon. Among the crus- 
tacea were new species of the Diastylide, and many 
forms of Isopoda, Amphipoda, and Ostracoda, several 
of them new to science. 
Two or three specimens were obtained at a depth 
of 1,215 fathoms (Station 28) of a very remark- 
able echinoderm belonging to the genus Pouwr- 
talesia, A. Ac. All these specimens were appa- 
rently immature, judging by the condition of the 
ovaries. I have named this species provisionally 
Pourtalesia phiale. After careful consideration I 
have come to the conclusion that it is not the 
young of a form of which we afterwards took a 
mature example in the cold area between Ftroe and 
Shetland (Station 64), which will be described here- 
after. Fine corals were constantly dredged in the 
more moderate depths, particularly great living masses 
of Lophohelia prolifera (Fig. 39), with smaller tufts
