Remarks .—In the great length and slenderness of the chelophores, in having the 
second segment of the palp much longer than the fourth, and in the very long hairs 
with which the limbs are beset, this species differs remarkably from all those hitherto 
described in this genus. 
The holotype described by Mr. Hodgson differs from the “ Terra Nova ” specimen 
here figured only in having the chelophores a very little shorter, the second segment 
of the palp only about one-third, instead of one-half, longer than the fourth, and the 
abdomen a little longer, rather more elevated, and more clavate. 
Ammothea striata (Mobius) ?

Ammotliea striata, Bouvier, 1913, p. 124, figs. 75-77. 
Occurrence. —Station 194, off Oates Land, 180-200 fathoms; 1 $. 
Remarks .—A single specimen of large size is referred, although with considerable 
doubt, to this species. Unfortunately, it is in such bad condition as to make a full 
determination of its characters impossible, the exoskeleton being soft and almost 
membranous, the body contracted, and the legs collapsed and crumpled.* 
The most conspicuous feature of the specimen is the shortness of the proboscis, 
which measures only about 9 mm., while the length of the trunk is about 14 mm. As 
* Mr. Lillie notes that the bottom at Station 194 consisted largely of “ undecomposed animal debris .”
