abbreviated tip. The brush-shaped bristles are distinguished 
by the great length of the teeth or processes at the tip, and 
one side is longer than the other. The ventral are similar 
to those in the 20th foot, the tips being minutely spinulose. 
The 40th foot has a single pranehial process, the dorsal 
bristles are more elongate, and the tips of the ventral bristles 
are knife-shaped, being short and acutely pointed. The 
serrations are less distinct. Twoblack spines support the foot. 
The 50th foot has two divisions in the branchial process ; 
the dorsal bristles are even more elongate, and the tips of 
the ventral shorter (Pl. XI. fig. 20). A strong bifid winged 
hook now projects above the ventral cirrus. A single black 
spine supports the foot. The glandular pad internal to the 
ventral cirrus is of large size. The tips of the dorsal bristles 
appear to be as minutely spinulose as those of the ventral, 
and the wings are marked by the usual striz. 
In the fragment of the posterior region of the body the 
male elements distend the parts. The feet have a rounded 
outline and three branchial filaments, the ventral papilla 
opposite their origin still being present. The foot has a 
single large spine, the tip of which pierces the surface 
between the dorsal and ventral bristles, a little above the 
short ventral cirrus. The dorsal bristles have longer and 
more slender tips, whilst the ventral have increased in 
strength, but no perfect example can be found. The foot 
thus possesses the strong simple spine and the strong bifid 
hook as levers, in addition to the bristles. The brush- like 
forms still have the same character as in front. 
The Lysidice multicirrata, Claparéde*, from the coast of 
Normandy, has compound bristles with taperimg tips, but it 
seems rather to lean to Morphysa.

Bank, which approaches the Eunice amphihelia of Roule +,

into detail. The head has the palpi deeply severed in front, 
and with a marked fold at their middle and the demarcation of 
an inner portion. ‘The tentacles are unusually long, but 
retain their several proportions to each other. The median 
extends backwards to the tenth segment in the preparation. 
The tentacular cirri are about twice the antero-posterior 
diameter of the first or peristomial segment. They appear
