of sharp spines, which appear as a single row when seen from the side as in figure 20. Dorsal setse of 
this bundle much larger than ventral, but differing from them in no other important respect. 
Third parapodium much shorter than second, squarely truncated at the end (fig. 21); posterior 
lip broad, rounded, anterior lip bilobed; dorsal cirrus with basal and long, lanceolate, terminal joint; 
apex extending more than half length of cirrus beyond apex of parapodium. Notopodium a small 
elevation on dorsal surface of neuropodium. Aciculse as in second parapodium. Dorsally a bundle 
of very fine setse, like those described for notopodium of second parapodium. On dorsal and ventral 
surfaces of neuropodium are other setse like those described above, the ventral bundle containing 
much the larger number; between these a row (5 in number in parapodium figured) of stout yellow- 
colored setse, with curved, bluntly pointed ends. At the apex a bundle of fine bristle-like processes, 
while from one side of apex arises a long, delicate, colorless spine, with two rows of minute processes 
along its basal portion (fig. 22). 
On following somites, beginning with seventh in one specimen and tenth in another, is another 
form of seta, found in bundles of 2 or 3 on dorsal surface of parapodium. These have a moderately 
stout inner axis, with a dense bundle of delicate radiating spines at the apex (fig. 23) . 
With the exception of the delicate setse first described, which disappear early, all the above 
forms of setse are continued into the posterior portion of the body. The shafts of the setse increase 
considerably in length, so that they stand out prominently from 'the sides of the body. 
Fiber glands are present, and the black chitinous ropes secreted by them are prominent in all 
somites behind the seventh or eighth. 
Dental apparatus a long, gently curved maxilla on either side, colorless except for the apex, which 
is light brown, and on either side a dental plate with about 16 denticulations. 
Collected at station 3892, 328 fathoms, on a bottom of fine gray sand. Type no. 5206 U. S.

Psammolyce fijiensis McIntosh, Report Challenger Expedition, vol. ill, p. 148, pi. xxi, fig. 6, pi. xxn, fig. 4, pi. xxiv, 
fig. 6, pi. xixi A, fig. 18. 
This was originally described by McIntosh from a single incomplete specimen. In the present 
collection was one specimen, also incomplete, undoubtedly of this species, though differing somewhat 
from McIntosh’s description. 
Only the head and about 38 anterior somites remained; length of this portion 11 mm. Proboscis 
protruding to distance of 4 mm. , being about as long as first 4 somites. On either side, above and below, 
at the end, are 11 papillae. Four large teeth in pharyngeal cavity. When pharynx is protruded the 
head is rotated upward so that the anterior pair of eyes, mentioned by McIntosh as invisible from the 
dorsum, are indistinctly seen through the flattened transparent basal portion of the tentacle. 
Terminal portion of tentacle absent, as was one palp. Other palp long, smooth, gently tapering 
to a blunt point, the tip extending beyond the end of the protruded pharynx, in this differing from 
McIntosh’s specimen, in which the palps were very short. 
Elytra cover rather less than half of dorsal surface; inner third of each and dorsal body surface 
between them densely covered with minute sand grains; anterior edge of each elytron, where it* is 
overlapped by the one in front of it, and outer half of exposed area free from sand. 
Some somites show, in addition to the compound setse described by McIntosh ( pi. xm a, fig. 18) , 
a few having a similar general form, but more slender, paler, and with a longer terminal joint. A few 
of the larger setse also show transverse rows of minute serrations near the end of the basal joint. 
Collected at station 3847, 23 to 24 fathoms, on sandy and stony bottom.
