40 STALK-EYED CRUSTACEA. 
Cymopolia fragilis Rarus. 
Plate VI., Fig. 4, 4°. 
Proc. U. S. Nat. Mus., XVI. 259, 1898. 
Carapace very short and broad, tuberculated, with granules scattered 
between the tubercles. Front cut into four blunt teeth, the two in the 
middle prominent, the outer ones short. Superior margin of the orbit cut 
by two fissures as is the lower margin also; there is a broad prominent lobe 
just below the internal orbital angle, with two teeth above it at the angle. 
The antero-lateral margin of the carapace is five-toothed, counting the promi- 
nent tooth at the outer angle of the orbit. There are two tubercles on the 
frontal region, twelve on the gastric, five on the cardiac (four of which are 
arranged in a transverse row and elongated transversely); eight or nine on 
each branchial, and a carina more or less broken up into tubercles just in 
front of the posterior margin of the carapace. The eye-stalks are furnished 
with two blunt tubercles near the edge of the cornea. The chelipeds are 
small, slender, equal. The third and fourth pairs of ambulatory limbs are 
very long, the merus joints with a low tubercular carina on their anterior 
margin and two longitudinal rows of tubercles on their upper face; the 
anterior distal angle is rounded off and not produced into a spine or tooth; 
the anterior edge of the carpi and propodi is sharp, and the upper face of 
these joints is two-ribbed. The abdomen and sternum are almost smooth. 
The difference in the shape of the abdomen between this species and the 
foregoing will be best appreciated by a reference to the figures. 
Length, 7 mm.; breadth, 11 mm.; length of ambulatory limb of the 
second pair, 26.5 mm. (merus, 8 mm.; carpus, 4.5 mm.; propodus, 7 mm. ; 
dactylus, 5 mm.). 
Station 3569. 52 fathoms. 2 males, 12 fem. ovig. 
eS 33TO.. O2 as 3 males. 
Cymopolia fragilis was first discovered by the “ Albatross” expedition of 
1889, off Lower California, in 58 and 71 fathoms.
