a variable power of changing colour under such conditions. The plaice and 
gurnards especially could be divided into two lots, (1) black or sub-black and (2) 
the usual light brown colour. The former lost their strong black tints in 
dying, returning more or less to the normal colour. Dabs, if we might so express 
it, seem to have little cliromatophore capability. One dab which had been injured 
near the tail showed that though the injured part had been healed it had not yet 
recovered the normal pigment— the injured region was white on the coloured side 
and near to it on the white side were a few scattered points of colour. A young 
dab, two inches long was found amongst the weed brought up in the trawl. 
Several sea urchins were also picked up. When one of them, measuring about two 
inches, was placed on its back in a bucket of water it took about four minutes to 
right itself, but only less than half that time when it was placed near the side of 
the bucket. Trawling commenced at 8-30 a.m., and was continued for seven 
hours. 
Skate Roads, June 2Gth. — At 11-20 one haul was made in excellent weather; 
the sea was smooth and there was a light easterly wind (Table G). 
Goswick Bay, June 28th. — An hour’s experiment was made at 6-45 a.m. 
(Table G). A second haul, however, resulted in the net being torn on a piece of 
wreckage, the fish caught being only one sandy ray and one flounder. The 
temperature of the air was 6G degs. F. and of the water 53 degs. F. 
Skate Roads, June 28th. — Beginning at 10-10 a.m., we gave hours to this 
bay. The temperature of the surface water was also here 53 degs. F. The hauls 
gave other than the fish detailed a large number of Corystcs cassivelaunus. 
Cambois Bay, July 3rd. — A strong easterly wind had caused a moderately 
rough sea. The wind on the day of the experiment was N.N.E changing to N. 
The temperature of the air was 57 degs. and of the water 55 degs. Starting at 
9-35 a.m. we fished for 5£ hours. The first haul yielded only a few small fish. 
The second haul of 1£ hours was the one measured (Table 6). A large number 
Portunus holsatus got, as we have often noted so commonly in the bays of the 
along the coast, were berried females. Several specimens of young Loligo were 
also procured during the day. 
Bltth Bay, July 3rd. — At 6-5 p.m. a haul of 50 minutes in this bay gave the 
small catch measured (Table 6). Berried Portunus holsatus were again common, 
and one speciman of Corystcs cassivelaunus was procured. 
Dkuridge Bay, July 10th.— The weather was good though there was a slight 
mist and some thunder with rain in the afternoon. The light wind was N.E. 
The temperature of the air was G4 degs. and of the water 58 deg. There was 
again a large number of berried Portunus holsatus. A female was opened and 
the heart was found to be beating 44 times in the minute. 
Alnmoutii Bay, August 14th. — The fishing showed a great improvement, 
though done in miserable weather. The wind changed from S.E. to S.W. in the 
morning but went back again to the east in a short time. Rain fell constantly 
the whole day. There was a moderate easterly swell which increased during 
the day.
