THE VOYAGE OF H.M.S. CHALLENGEE. 
A closely allied form comes from Station II. (off Setubal), January 13, 1873 ; lat. 
38° 10' N., long. 9° 14' W.; depth, 470 fathoms; surface temperature, 57°'0 ; sea-bottom, 
green mud. The distribution of this common form is very wide. 
The first-mentioned is of average size, and the snout, which is of fair length, is marked 
by a median longitudinal groove. The anterior feet have a somewhat large dorsal cirrus 
with a globular extremity, and a small dorsal process of the foot proper, which does 
not extend so far outward as the setig-erous lobe of the division. Beneath are the 
O 
somewhat large inferior setigerous lobe, and a long lanceolate process Avhich projects far 
beyond the latter ; while ventrally the lower lobe has a broad point. 
The simple superior bristles are very distinctly serrated along the edges. The 
inferior compound bristles are characterised by a marked irregularity in size, the shafts of 
the upper being about thrice the thickness of some of the others. The terminal pieces 
of these are comparatively short and distinctly serrated. A similar proportion exists in 
the lower group of the inferior bristles, except that the thickest are ventral instead of 
dorsal. The same arrangement is observed in the British examples of the species. 
Posteriorly all the processes of the body are elongated, but the bristles retain the 
nharacters just described. 
In the example from Station II. the structure of the foot is essentially similar, as is 
also the disproportion in the size of the shafts of the bristles, but the dorsal simple 
bristles and the tips of the inferior are very much longer. 
In transverse section the small example from Station 75 presents cords more 
distinctly separated than usual, and the ventral sulcus between the attachments of 
the strong circular coat is broader than in the ordinary form. The papilla above the 
foot is globular, and has a narrow pedicle. Eeproductive elements appear above the 
bases of the feet. 
The specimen procured off Setubal is so distended, apparently by the reproductive 
products, that the structure of the body-wall is indistinct. 
Glycera kerguelensis, n. sp. (PI. XXXVa. figs. 3, 4). 
Habitat . — Dredged at Station 149 h (off Christmas Harbour [?], Kerguelen), January 
29, 1874; lat. 48° 45' S., long. 69° 14' E.; depth, 127 fathoms; surface temperature, 
39° ‘8 ; sea-bottom, volcanic mud. 
The specimen is about 45 mm. in length and 5 mm. in breadth at its widest part. 
In external appearance this form very much resembles Glycera capitata, though 
towards the tips of the posterior feet there is more brownish pigment. 
The intestine contained a brownish mass consisting of bristles of Annelids, numerous 
Diatoms, a few sponge-spicules, and sand-grains.
