THE VOYAGE OF H.M.S. CHALLENGED. 
(3) Carbasea elegans, Busk (Pl. XVI. fig. 5). 
Carbasea elegans, Bk., Brit. Mus. Cat., vol. i. p. 53, pl. liv. figs. 6, 7, pl. lvi. fig. 3. 
Character. — Zoarium composed of narrow ligulate divisions. Zocecia oblong. Mem- 
branous aperture almost the entire front, square at the lower border. 
Habitat. — Station 162, off East Moncoeur Island, 38 fathoms, sand and shells. 
Station 314, lat. 51° 35' S., long. 65° 39' W., 70 fathoms, sand. 
[Tasmania, B. M.] 
(4) Carbasea pedunculata, n. sp. (Pl. XVI. fig. 4). 
Character. — Zoarium composed of ligulate branches, all in one plane, dividing 
dichotomously and of uniform width (about 0T25"). Zocecia broadly ovate, but irregular 
in size and shape. Branches bordered on each side by a continuous chitinous tube, and 
the two tubes are continued into a peduncle about 0"’5 to '75 long, terminating in a 
tuft of capillary fibres. 
Habitat. — Station 75, lat. 38° 38' N., long. 28° 28' W., 450 fathoms, volcanic mud. 
Station 76, lat. 38° 11' N., long. 27° 9' W., 900 fathoms, Globigerina ooze. 
The single specimen of this species included in the collection is unfortunately in a very 
imperfect condition— torn and ragged — so that the full dimensions of the growth cannot 
be determined from it. The zooecia are amongst the largest with which I am acquainted, 
about 0"’05 x ’035 ; and the zoarium, like that of most of the very deep water forms, 
is extremely flaccid and tender. 
(5) Carbasea moseleyi, n. sp. (Pl. XXXIII. fig. 4). 
Character. — Zoarium about 0"'75 high, narrow, fan-shaped, and apparently shortly 
pedunculate ; bordered on each side by a continuous chitinous tube. The growing edge 
serrated. Zocecia hexagonal, 0" - 04 x '035, very convex in front, flatter behind ; wall 
very transparent, but entirely calcified. A series of six apparent punctures on each side 
in the upper half of the front only, the series being continued across the top above the 
mouth. Besides these, a variable number (8 to 10) of rather smaller punctures towards the 
upper part of the front. On some of the zocecia a large horse-shoe-shaped mark is seen 
in the lower part of the front, apparently representing a cavity in or just within the 
anterior wall. Orifice large, crescentic, with a very strong chitinous lip. 
Habitat. — Station 170, off Kermadec Islands, 520 fathoms, volcanic mud. 
This very remarkable and extremely beautiful species is represented by only a single 
specimen, for which I am indebted to Mr. Moseley, who had mounted it while quite recent
