until the bearings of Tasman Island and 
I ape Uuoul showed the vessel was seven 
miles off -hoie; the depth then about 
70 fathoms. The work here was carried 
out under difficulty, with a strong breeze 
from the nor til-east, and considerable 
sea running. The steamer was rolling 
gunwale in, water occasionally over the 
deck, and the heavy derrick, from which 
the dredge was worked, swinging violent¬ 
ly with (he rolling of the vessel. (inly 
a small amount of stuff’ was brought up 
in the few diags, and, piobably with a 
heavy load in, the line parted in a 
h avy roll, and the large dredge from 
the University, with over 80 fathoms of 
rope, was lost. 
On March 21. in taking parties to the 
port and to Oakwood, three diags »eie 
tried—one near the Settlement, one 
nearer the Isle of the Head, anil the 
thiiil in a deep hole beyond the isle. 
Thick blown mud was brought up each 
time, with a few interesting varieties <d 
shells, crustacean, cake urchins, etc. 
Amongst the molluscs from the frag¬ 
mentary polyzoio sand and old shells 
brought up from 70 fathoms, Mr. May 
has shown me the hollow horn-like Den- 
tnliiim virgula, with small embiyonic 
shells, from which they apparently grow, 
still showing at the smaller en I. In- 
recorded from Tasmania. I wo oi three 
pair of laidita losulenta, a fine specie-, 
ot cucklc; to the uninitiated veiy like 
Ti igonias in appeal a nee; large massive 
shells. A Cuspidaria, a white cockle 
shell, about ball an inch across, the 
length doubled by the one end of the 
valves, narrowing out in a hollow tube. 
Mr. May pointed out that this agrees 
closely willl a species dredged by the 
1 liallenger in 1,000 lathoms ott the 
Azores. As it is scarcely lik.ly to be 
the same, it is piobably a new species. 
A tiiangular-shapod shell of about the 
game .size could not be placed at all. I n- 
fortunately, only an old worn valve and 
a fragment of a luiger one found, so 
is practically usel -s. Already a con¬ 
siderable number of smaller shells, mem¬ 
bers of the laige family of Marginellas, 
etc., have been picked out, and mole 
new oi rare vaiieti >s may be found 
amongst these smaller species. 
Almost every crab fiom the 70 fathoms 
is either new, or not taken on our pre¬ 
vious trips. A handsome white oral), 
bristling with points or tubercles, was 
a welcomed prize, for a badly-damaged 
specimen was taken at about the same 
depth off Schoiiten Island, Easter, 1010, 
and pronounced "new” at the Austra¬ 
lian Museum. Sydney. A fine pair 
of the family Maiidte, or “spider crabs,’' 
bearing long stout points on their cara¬ 
pace, resembles one taken on the same 
occasion, and supposed to be a new 
species of “Pugettia,” but as that crab- 
i- now in Sydney awaiting description 
and name they cannot be. compared, 
lint a still more "spider-like" crab is a 
fine Homolidas apparently of tb. genu- 
Latreillia, with n pointed tiiangular 
body of about half an inch long, and 
spindle legs of four times that length. 
The long thin eye-stalks, carrying large 
eyes, are half as long as (lie body- Have 
never taken any of this family before. 
Another crab nut dredged before rough 
odd-shaped, with a couple of feeble legs 
turned up on to the back, as if to carry 
a mantle or protective covering, as d<>

Arthur a couple of Callianassidse tiny 
lobster-like creatures, with almost trans¬ 
parent covering, and one laigely develop¬ 
ed front claw. 
In Professor T. Thompson Flynn’s 
specimen jars all the lower forms of 
life found a resting place. And although, 
from the small amount of stuff brought 
up, the "take” is more limited than 
usual, still there are curious and inter¬ 
esting creatures amongst it. Tubicolous 
norms in slightly curving, horny, quill- 
like eases, tour inches in length; some 
specimens of the beautiful fan-shaped

the deeper water. Varieties of (lie star- 
fisli family; handsome Asteroids, very 
different from the species usually found 
i:i shallow water; the largest a line five- 
rayed slur nearly six inches across; 
<Iphiuroids, with long wi‘thing arms; 
Aseidians. sponges, etc. 
These curious and complicated forms

higher animals. molluscs, Crustacea,

sified; so the Professor can say very 
little about them yet. Hut it is almost 
certain that some of them will piovc-

ARTHUR DISTRICT. 
(By A. N. Lewis.) 
Safety Cove, Port Arthur, is not one of 
our many places of great geological inter¬ 
est, hut the results of the camp in this 
line were by no means unsatisfactory, be¬ 
cause. although nothing absolutely new 
was discovered, at least one very interest¬ 
ing Ini malion, described fully below, was 
found. 
The oldest rocks in the vicinity of the 
camp were the cliffs at Point Puer. They 
are composed of almost perfectly horizon¬ 
tal layers of pernio-carboniferous lime-
