The stem is attached by a slight calcareous expansion at about its 
35th joint to one of the rays of a Rhabdammina ahyssorum ; and 
it then passes on to form two other spreading attachments, with 
radicular branches sprouting from them on what appears to be a 
portion of a tubular hydroid. 
8. Antedon eschriehti, Mull. sp. 
H.M.S. ‘Torcupine,” 1869. Station 57. Lat. 60° 14' K, 
long. 6° 17' W. 632 fathoms. Temp. 30°-5 F. 
Sir Wyville Thomson stated that considerable numbers of this 
species were obtained in many of the cold area hauls; and he 
noted their small size as compared with more northern specimens. 
JN’o. 57, however, is the only station of which any record has been 
preserved; and it is interesting as being by far the greatest depth 
at which this species has yet been met with. Its usual parasite 
Alyzostoma gigas^ Liitken, MS., was also obtained at this station. 
Two pentacrinoids besides that of Ant. dentcda were dredged in 
the cold area ; but I do not think that either of them can be 
the one referred to by Sir Wyville Thomson in the following- 
passage : — “A single example of a pentacrinoid in an early stage 
was found associated with Ajit. escludchtii. It resembled closely the 
larva of Ant. sarsii but the specimen was not sufficiently perfect for 
a critical examination.’' Neither of the larvae which I am about to 
describe is at all like that of Ant. dentata, and I fear, therefore, 
that the one mentioned by Sir Wyville Thomson has somehow 
been mislaid. 
' No. 1. In this larva there is no trace of cirri, the anal plate 
separates two of the radials, and the arms are just beginning to 
sprout from the radial axillaries. There are five discoidal joints at 
the top of the broken stem, which is much more robust than that 
of the corresponding stage of Ant. rosacea ; while the head, which 
exceeds 1 mm. in length, is nearly twice as big as that of the 
rosacea larva. The orals which rest directly on the radials recall 
those of Hyocrinus, having a deep median groove, only more marked 
than in that type, with the lateral edges folded over somewhat 
strongly. This interesting larva may perhaps belong to Ant. 
'phalangium, but I rather doubt such being the case. For that 
species is almost the nearest ally of Ant. rosacea ; and from what I
