of the Virijinian Coast. 9 
Tentacular cirri arise from an elongated cylindrical base; 
superior lost; inferior as long as the head, inner half 
cylindrical, outer half conical ; covered from near their 
origin for two-thirds of their length with rather coarse 
papillae. 
Elytra, probahly 12 pairs ; very minute, transparent, 
smooth, edge without appendages. They were colorless, 
with numerous very light brown specks and streaks. 
They barely covered the base of the feet, not reaching to 
the middle line of the body. The shape varies, some 
being as shown in pi. II, f. 16, others as in f. 17. 
Dorsal cirri long, projecting beyond the setae, in all 
respects similar to the tentacular cirri. Feet long, nearly 
cylindrical, bilabiate. Dorsal ramus a mere papilla on 
the upper surface of the foot. Setae of dorsal ramus (pi. 
II, f 18) delicate, one edge very finely denticulated, ter- 
minating in a long capillary point. Setae of ventral ramus 
of several kinds: first and second setigerous segments, the 
setae terminate in a single sharp point, at some distance 
below which is a long series of sharp teeth (pi. II, f. 20); on 
the remaining segments, except the last two, the setae are 
bidentate, serrate below the apex, the teeth being arranged 
in short series. The superior terminal tooth is much 
curved (pi. II, f. 19). In the penultimate segment these 
setae are replaced in part by strong hooked setae ; while 
in the last segment the hooked setae are the only ones 
found (pi. II, figs. 21, 22). It seems probable that the 
function of these hooks is to hold on to the body of 
Lepidameiria commensalis, under the elytra of which they 
are found. Length about 2°"". 
LEPIDAMETRIA n. gen. 
Lateral margins of the head prolonged to form the bases 
of the lateral antennae. Middle antenna with distinct basal 
article. A small facial tubercle. Body elongated, flattened.
