hchyrocerus minutiis, Lilj. 
Fairly common in the harbour at Cullercoats and at other places 
on the coast. Obtained also from a piece of wreckage at Skate 
Eoads. 
Podocerus falcatus (Mont). 
This species was got frequently from the harbour at Cullercoats 
and was obtained also at Craster last year. 
'Podocerus herdmani (Walker). 
One male from Skate Roads, 22nd Jmie, 1897. 
Erichthonius ahditus (Templeton). 
One or two specimens from off Cullercoats. 
Erichthonius hunteri (Sp. Bate). 
In tubes 2J miles off Souter in 21 fathoms. They measure — 
the males less the antennae — 7-8 mms., and are therefore longer 
than those seen by Sars. Moreover, the carpal process is longer 
and reaches rather more than half the length of the propodos. 
Also from 82 miles E.N.E. Tyne in 45 fathoms. 
Family — Corophiida. 
Siphonoecetes colletti, Boeck. 
This species is pretty common on the sand near to the rocks at 
the south end of Druridge Bay. While some of them agree with 
the description of this species others have gnathopoda more like 
S. fypicus. The lateral processes of the cephalon, moreover, nearly 
reach to the end of the first segment of the lower antenna and are trun- 
cated distally. The following observations on the living animal may 
be interesting. I took one out of his tube and put him back into the 
water. He showed at first signs of helplessness, for Paratylus uncinatus 
was dodging about, but recovering to some extent he began to 
explore. Finding a tube containing a tenant slightly smaller than 
himself he got alongside and presented his antenna at the front 
entrance and the back entrance in rapid succession. This made the 
rightful inhabitant withdraw, but the would-be evicter after thus 
making a display remained quiet. The former then cautiously came 
out at the front door and not seeing the enemy withdrew himself 
from the tube so as to get a look behind. This was evidently what 
the latter w’as waiting upon. He suddenly plunged in at the back 
door and actually drove the poor proprietor out in front of him. At 
first this ill-used Siphonectes showed signs of trying the same tactics 
on a still smaller neighbour, but he proceeded instead to make a 
new tube. I next put two together into a small dish with only one
