respect, however, station 399 is worthy of note, for here the 
surface tow-netting contained, in addition to numerous Ophio- 
pluteus larvae, several minute Asteroids just past the larval 
stage, a few small larval Echinoids, and several Holothurian 
larvae of the ‘‘barrel’’ type. 
oLYCHAETA.—Polychaet larvae were of comparatively fre- 
quent occurrence throughout the whole period of investigation. 
Unfortunately in the present state of our knowledge it is im- 
possible to identify specifically the various forms met with, and 
all that can be done is to refer them to their different families 
or genera. The families represented by their larvae in the col- 
lection are as follows :— 
Alciopidae. Polynoidae. 
Disomidae. Spionidae. 
Poecilochaetus, sp. Syllidae. 
Magelonidae. Terebellidae. 
Nereidae. Tomopteridae. 
Phyllodocidae 
At station 399, several long Polychact worms of a pink 
colour were seen swimm 
e resulting catch was usually fairly copious and con- 
tained the following organisms :— 
Pisces.—Fish ova and larval fish. 
Tunicata—Several examples of a species of Salpa. 
Ascidian larvae. 
Crustacea.—Larval Pagurid crabs. 
ab zoeae. 
Crab megalopae. 
Young Prawns in the post-larval stage. 
Ostracoda. 
Amphipoda. Several species; including exam- 
ples o Ima, sp. 
Lucifer typus, auct. 
Evadne, sp. 
Copepoda (a list of the Gymnoplea has already 
been published). 
Copepod nauplii. 
Lepas nauplii. 
Brachiopoda.—Several examples of Lingula larvae 
Mollusca.—Lamellibranch larvae. .
