THE VOYAGE OF H.M.S. CHALLENGEK. 
ovoid form, fragments of Eadiolariaiis, minute Crustacea, an occasional bristle of an 
Annelid, peculiar pointed structures like tips of spears, and probably allied to similar 
organs formerly mentioned in other species, minute Nematoids (it may be those of some 
of the prey, e.g., Pteropods), minute bodies with double disks, numerous Pteropods like 
Ilyalea, from the youngest stages up to adult size, a fine Echinocleres like Echinoderes 
dujardinii, Clap., and finally many Diatoms and Coccoliths. The Echinoderes had 
its cephalic spines included, but pressure caused extrusion. 
The specimen is enclosed in a smooth tube of somewhat brittle opalescent chitin, 
minutely dotted under a high power. No structure adheres to it externally, the only 
object, indeed, attached to it internally is an occasional hook of its own. 
The uncini of the foregoing differ decidedly from those of Marenzeller’s Thelepus 
japonicus,^ in the form of the anterior inferior region beneath the mucro, and in tbe 
curve of the inferior margin.

Habitat. — -Dredged at Station 144a (off Marion Island), December 26, 1873; fat. 
46° 48' S., long. 37° 49' E.; depth, 69 fathoms; surface temj^erature, 41°‘0 ; sea-bottom, 
volcanic sand. 
An example attached to a mass of Serpula narconensis was dredged in Balfour Bay, 
Kerguelen, January 9, 1874, in 20 to 60 fathoms. 
Other examples come from Station 149, off Christmas Harbour, Kerguelen, January 
29, 1874, in 120 fathoms. 
Also from Station 150 (between Kerguelen and Heard Islands), Februar)?’ 2, 1874 ; 
lat. 52° 4' S., long. 71° 22' E.; depth, 150 fathoms; bottom temperature 35°’2, surface 
temperature 37° ‘5 ; sea-bottom, coarse gravel. 
Two fragments were found at Station 151 (off Heard Island), February 7, 1874; 
depth, 75 fathoms; surface temperature, 36° '2 ; sea-bed, volcanic mud. One is distended 
with ova. 
A large portion of the posterior end of the same species (so far as can be ascertained 
from the hooks and other parts) occurs at Station 313 (Strait of Magellan), January 20, 
1876 ; lat. 52° 20' S., long. 67° 39' W.; depth, 55 fathoms ; bottom temperature 47°'8, 
surface temperature 48° '2 ; sea-bottom, sand.
