until about nine p.m., when, after a final haul in the 
Turbot Hole, the biologists were again landed on Puffin 
Island. The following is a summary of the observations 
made on this expedition :— 
(A) Turbot Hole, off Puffin Island, sixteen fathoms; 
two good hauls:—Cucumaria planci, Thyonidium drum- 
mondi, Zoophytes, and many other things. 
(B) West of “‘ Little Mouse,” round Point Lynas, nine- 
teen fathoms, gravel, shells and sand; one haul :—Hydrac- 
tinia, Sponges, Dentalium and Hchinocyamus. 
(C) Off Porthwen Bay, seventeen fathoms; one haul:— 
Pecten varius, Fissurella greca, Cyprea europea, Antedon, 
Sabellaria, Phascolosoma vulgare (Syrinz harveyi), Den- 
talium entale, and Ascidians (Ascidia plebeia, Styela 
grossularia, and Polycarpa pomaria). 
(D) Same, two miles off shore, twenty to twenty-two 
fathoms; two hauls:—Garvera nutans, Antennularia 
ramosa, Antedon rosaceus, Fissurella greca, Murex erina- 
ceus, Natica, Nucula and Cellepora. 
(EZ) Off Point Lynas; in first haul lost large dredge, then 
one haul with small dredge :—Spatangus purpureus in sand. 
(F) Off Dulas Island, thirteen to fifteen fathoms, sand 
and shells :—Solaster papposa, Sponges and Ascidians. 
(G) Same, further off land, twenty fathoms :—Spatangus 
purpureus in abundance. 
(H) Off middle of Red Wharf Bay, twenty fathoms :— 
Spatangus. 
(I) Turbot Hole, sixteen fathoms; one haul:—Same 
results as before. 
These hauls yielded many interesting Crustacea to 
Mr. Walker. Some of the best of these were obtained 
by placing the sand and gravel brought up in the dredge 
in dishes of sea water, when many Amphipods swam out.
