Willemoes-Suhm writes : “ On the pinnulse of the Comatulse we found Myzostoma 
under rather peculiar conditions. Some of the pinnulse had enlarged hy excrescence and 
were rolled up so as to form a cavity, in which, in two cases, a larger and smaller 
Myzostoma were found. This reminds me very much of Trematodes, which, like 
Monostomum fdba in the skin of birds, live always in cases or sacs in pairs, one 
individual being much larger than the other, the one acting probably as a male and the 
other only as a female ; this leads in some cases, as in Distomum oJceni on the branchiae of 
Brama rayi, to a perfect diversity of sexes. Perhaps there is something very similar in 
Myzostoma, which is hermaphroditic and has many affinities with the Trematodes. 
Among the higher Decapods there were an 'Alpheus, never got before in deep water, and 
two males of a new species of Willemcesia, [ = Pentacheles euthrix]. This genus has not 
made its appearance since we left the Southern Atlantic, where in a depth of 1900 fathoms 
we got Willemcesia leptodactyla, to which this new species is most closely allied, 
differing from it in being smaller and in having two excisions of the red chitinous upper 
layer of the carapace where one would expect to find the eyes. A very large-celled 
Lepralia was observed on the pumice-stones. ”

Moseley writes : “ A shark [ Carcharias lamia] was caught ; four or five small pilot 
fish were about it. On it were numerous specimens of Caligus, a few of which again had a 
Lepas on them often almost as big as themselves. The Caligi had a pink colouring matter, 
giving an absorption band. On the shark being skinned I noticed that a layer of superficial 
or skin muscles, only about ^ inch thick, was coloured dark red like mammalian muscle, 
the main muscular mass being pale, almost white ; this condition is comparable to that 
in the marine Gasteropods. Murray, on going out in the dingey, met with floating sea- 
weed, apparently a Fucus with large vesicles, like Fucus nodosus. In these masses were 
a small fish ( Lints porosus) and numerous crabs ( Nautilog rapsus ) , mimicking the colour
