dorsum of the narrow body, and uniform in outline. They are 
perfectly smooth on surface and border, and thus differ from those 
of the other British species. A shallow notch occurs at the exter- 
nal margin, and a more acute one at the hilum. The distribution 
of the nerves is well seen. 
The feet have an unusually long, straight branchial process 
dorsally, and three ciliated pads beneath it on the dorsal curve. 
The dorsal lobe is clavate (narrower at the base), much bevelled 
dorsally at the tip, and with a long, slender papilla stretching 
from the apex. The dorsal bristles form a long tuft of rather 
boldly serrated bristles superiorly, and they diminish towards the 
ventral edge; the ventral lobe forms an irregular spear-head, the 
longer slope being inferior, and the apex from which the spine 
projects is prominent, and bears a papilla. Inferiorly is another pro- 
minence behind the lower group of bristles. The upper ventral 
bristles are slender, the distal ends of the shafts having eight 
or nine whorls of spikes, the terminal process apparently being 
simple—in the form of a tapering acicular process with a needle- 
like tip, a condition probably due to repair, since some show a 
many-jointed needle-like tip. Others, with stronger shafts, next 
follow, with shorter, simple tips numerously jointed. Some of the 
more slender shafts at the ventral border of the stout series present 
many-jointed tips, with a minute claw. ‘Then follows a large, 
fan-shaped group of most slender bristles, with a few spines at the 
tips of the slightly-curved shafts, and long (6-8) jointed, hair- 
like tips. The ventral cirrus is long and subulate, and its tapering 
tip reaches as far as the apex of the ventral lobe. 
So far as can be observed, this is the nearest approach to 
Leanira, only the more slender forms of the stouter series of 
bristles in the ventral division presenting a very finely bifid ex- 
tremity.
