and by extending the body and again bringing up the pleon to its 
reflexed position to push its way along the tube.* 
The tube (see fig. A) is cylindrical, of the same diameter 
throughout except at each end where it is somewhat widened ; the 
two ends are quite similar and appear to be equally and indiffer- 
ently used by the animal. The tube is quite free and unattached 
and is no doubt carried about by the animal when it moves. The 
material of which it is made is fairly tough, the surface is smooth 
and the whole appears to be formed from the secretion produced 
by the glands in the first and second pereiopoda, no sand grains 
being used as in Gerapus sismithi. 
The tubes that I have seen are all of the same shape, but they 
very much in size, the largest being about -46 inches long and *03 
inches in diameter, others being of only half these dimensions. 
Many of the tubes and especially of the smaller ones were empty 
and I presume that when the animal has grown too large for its 
tube it leaves it and secretes another and larger one. 
/ From the description which has now been given of the male of 
this species it appears that G.Jtindersi is not very different from 
C. sismithi described by Stebbing from Kerguelen Island ; it differs 
from that species however in the antennae, to some extent in the 
second gnathopoda and also in the armature of the uropoda.

. Fie ad rather large ; a strong transverse ridge crosses the occiput 
immediately behind the eyes, ending on either side in a blunt 
point placed at the postero-superior angle of the orbit ; from this 
runs forward an inwardly curved, elevated, supraciliary ridge 
which is continued on the snout by a conversely curved angular 
canthus rostral is ; these ridges form the margin on the forehead 
of an oval, and between the orbits of a subtriangular, depression; 
loreal region concave ; the length of the snout is one and two-fifths
