moon-shaped. ‘They are smaller than those of 8. limicola, 
and the pairs on each side nearer each other. The palpi are 
very long and slender. The first pair of feet and the parts 
amalgamated with them agree with the typical form. 
The body is slender and elongated, tapering to the vent on 
the tip of the tail dorsally. The only complete example had 
about 80 bristled segments, and in spirit measured an inch 
and a half. ‘The feet are prominent, but the nephridial 
eminence is indistinct and devoid of a papilla. The scales 
are thin, somewhat translucent, and entirely cover the dorsum 
—indeed, they overlap considerably. ‘The first pair are small, 
ovate in outline, and have the margin surrounded by a series 
of short clavate cilia, while the surface is studded with small 
conical papilla. ‘The typical scale (PI. ILI. fig. 5) is more 
or less reniform, and, with the exception of the anterior 
portion of the inner border and the anterior margin, the 
circumference has a close series of clavate cilia, which are 
largest on the external border and diminish before disappearing 
from the inner edge. The entire surface of the scale is dotted 
with the minute conical papille. Posteriorly the chief changes 
are the diminution in the size of the scale, its shorter and 
broader reniform outline, its greater translucency, the reduc- 
tion in number and size of the cilia on the external and poste- 
rior border, and the paucity of the conical papille on the 
surface. ‘The scales thus differ from those of known species. 
The first foot has a single spine, and bears the dense tufts 
of bristles conforming to the dorsal type, but somewhat 
stronger than those of the typical foot. The second foot has 
curved dorsal bristles springing from a division a little less 
prominent than the ventral, and with several lobulated papille 
(““stylodes,” Pruvot and Racovitza) at its tip, each bristled with 
stout clavate cilia. ‘The ventral lobe is massive, with several 
blunt clavate papillae. The upper bristles have numerous 
rows of spines on the convexity at the end of the shaft, and 
long, slender, six- or seven-jointed distal pieces with a 
minutely bifid tip, such bristles thus conforming to the inferior 
ventral series in the typical foot. The stronger bristles in 
the middle of the foot have distal pieces of two joints, while 
inferiorly the bristles again become slender and the terminal 
pieces longer, while the rows of spikes on the end of the 
shaft are fewer. ‘lhe ventral cirrus is subulate and smooth. 
In the typical foot the dorsal curve bears three top-shaped 
ctenidia, and a group of clavate papille bristled with minute 
clavate cilia project from the tip of the dorsal division, The 
bristles are long, tapering, and slender, their tips extending 
beyond those of the inferior division. The ventral lobe like-
