Remarks.—Most of the specimens are in poor, or very poor, condi- 
tion. Only one of the largest specimens, 200 mm. in diameter — none 
exceed that size — from station 5568 and a small specimen from sta- 
tion 5683 have each a couple of oral spines with the hoof preserved. 
In the latter a small barnacle of the genus Scalpellum is attached to 
one of them. 
Only a few of the specimens have kept their original dark purple, 
or black, color. Most of them are yellowish, though I have little 
doubt that these were originally dark colored also but have lost their 
color gradually. 
In a young specimen 21 mm. in diameter from station 5492 I have 
found a couple of ophicephalous pedicellariae. Unfortunately no 
tridentate pedicellariae are found in this specimen, but a comparison 
with other young specimens, slightly larger, seems to leave no room 
for doubt that it is really a young Hygrosoma hoplacantha, so that 
also this species may have ophicephalous pedicellariae when young, 
and that will then probably hold good for all the species of Hygro- 
soma, though as yet not known in H. luculentum. It is noteworthy
