The eyes are also much larger than in the former species, and are all visible from the 
dorsum. 
In many examples numerous adventitious bristles had penetrated the dorsum. 
Lagisca [Agnodice) moseleyi, n. sp. (PI. VI. fig. 6 ; PL Xa. figs. 7, 8). 
Habitat . — Trawled at Station 106 (in the middle of the Atlantic, in the line of the 
tropics), August 25, 1873 ; lat. 1° 47' N., long. 24° 26' W. ; depth, 1850 fathoms ; bottom 
temperature 36°’6, surface temperature 78°‘8; Globigerina ooze. 
A fragmentary specimen without scales and somewhat injured, as indeed most 
soft forms from deep water are. It is of considerable size, measuring 23 mm. in length 
and nearly 18 mm. in breadth, the bristles greatly increasing the diameter. The body 
is quite pale throughout, and seems to be in process of regeneration posteriorly. 
The head (PL VI. fig. 6) is pale, with two somewhat ovoid whitish masses anteriorly, 
like bleached eyes, and posteriorly two paler rounded spots on each side of the middle 
line. The palpi are long, rather slender, and gently tapered from base to apex. They 
also show faint longitudinal striae, and under a lens the sides are downy, from a dense 
series of somewhat long slender papillae with very slightly bulbous tips. The proboscis has 
a little dark pigment internally, a feature of interest in connection with the external pallor. 
The dorsal cirri are long, slender, and filiform distally, gently tapered from base 
to apex, and covered with long cilia, which extend far upward on the tip. The cilia 
have bulbous extremities. The tips of the cirri extend beyond the bristles on each side. 
The ventral cirri pass very considerably beyond the bases of the ventral bristles, are 
slender and tapered, and are covered with long cilia similar to the foregoing. The 
ventral papillae project distinctly about the eighth foot, and are continued backwards as 
large and proportionally thick processes, which differ entirely from those of Lepidonotus 
and Lagisca. 
All the bristles are of a very pale straw colour and remarkably long. The dorsal 
(PL Xa. fig. 7) are long, slender, and nearly straight, with the exception of a few of the 
upper and inner series. The length of the hispid region is characteristic, and the rows 
of spines very distinct, so that at first sight it resembles an Evarne. Below the spinous 
region the shaft is striated longitudinally, and the strise continue upwards nearly to the 
tip. The latter is peculiar, being probe-pointed and slightly curved. Many have a 
blackish granular deposit of a parasitic nature placed at intervals on the shafts, so that 
they are moniliform under a lens. 
The ventral bristles are likewise extremely long and slender. The shafts are finely 
striated, and a distinct dilatation occurs, as usual, where the serrations commence. The
