mented, situated at the top of a relatively small eye-tubercle, the 
length of which is about twice its diameter. The abdomen is about 
three-fourths the length of the body, (the latter measured from the 
anterior margin to the base of the abdomen). Along the top of the 
abdomen is a row of finger-like, multi-spine-bearing processes similar 
to those on the legs to which I will refer shortly, but much smaller 
than the three large ones previously mentioned as on the back. The 
diameter of the abdomen is about one-fifth its length. The chelifores 
are stout and slightly surpass the proboscis in length; they are rudi- 
mentary in having the chele undeveloped. The shaft is set with quite 
a few multi-spine bearing processes. The basal segment is about the 
same size as the terminal segment, but the shaft is one and one-half 
times as long as their combined lengths. The palpi are nine-jointed, 
surpassing the end of the proboscis by one-third their length. The 
first joint is shorter and broader than the rest; the second is the 
longest, being almost one-third the whole length of the palpus; third 
joint very short; fourth joint not quite as long as second. A ridge 
across the fourth jomt makes it appear like two joints as viewed 
from above. The terminal joints diminish in order. The first six 
joints have very few hairs, while the terminal joints are thickly set 
with hairs about as long as the diameter of the fourth joint. The 
second joint is thickened at the ends but the other joints are not 
noticeably so thickened. The average diameter of the palpus is 
about one-half that of the chelifores. The ovigerous legs are nine- 
jointed; their diameter about half way between those of palpus and 
chelifores. The joints in order of length (except the first, which is 
short and broad), 4, 2, 5, 3, 6, 7, 8, 9. Legs are rather short and 
powerful with numerous, multi-spine-bearing, finger-like processes, 
especially on the coxa and two tibial joints. On the two tibial joints 
these processes are arranged in a double row down the back of the 
joint. The first and third coxal joint are sub-equal in length, the 
second one and one-half times as long. The femur is as long as the 
combined length of all three coxe; the tibial joints two-thirds as long 
as the femur and but slightly longer than the tarsus. The claw is 
over three-quarters the length of tarsus, folding down between two 
rows of stout spines on tarsus. No auxiliary claws. Genital open- 
ings not apparent. Color light straw. Measurements in mm.: 
Proboscis 1.424; body 1.2; abdomen 1.1; leg 6.35; diameter of lateral 
processes .5. 
This single specimen was swept from fucus in July and when 
taken, was so covered with litter which was imbedded among the 
spines, that no idea of the real aspect of the creature could be ob- 
tained until after boiling in KOH. This litter rendered it very hard 
to find among bits of fucus even when we knew it was there and its
