(4) Menipeci jlabellum, Lamouroux. 
Cellularia ornata, Ek., Brit. Mus. Cat., p. 20, pi. xxvi. figs 3, 4. 
1 Menipea Jlabellum , Lamx. 
Cellaria Jlabellum, Ell. and Soland. 
Habitat. — Simon’s Bay, Cape of Good Hope. 
[Algoa Bay, Natal.] 
(5) Menipea jlagellifera, n. sp. (PI. IY. fig. 1). 
Character . — Zooecia six to nine in each internode, obovate (viewed behind). Aperture 
about half the length, regularly oval. Peristome thin, quite smooth. A single oral spine 
above on the outer side. A small angular avicularium to every cell, and a pouch-like 
vibracularium on the front below the aperture. 
Habitat . — Station 149d, Royal Sound, Kerguelen, 20 to 60 fathoms. Station 
149h, i, k, off Christmas Harbour, 45 to 127 fathoms. Station 313, lat. 52° 20' S., 
long. 67° 39' W., 55 fathoms, sand. Station 314, lat. 51° 35' S., long. 65° 39' W., 70 
fathoms, sand. Off Marion Island, 50 to 75 fathoms. 
(6) Menipea marionensis, n. sp. (PI. IY. fig. 3, and PI. XIV. fig. 9). 
Character . — Nine to fifteen zooecia in each internode, each series facing outwards so as 
to form an obtuse angle down the front of the branch ; very little contracted below. Aper- 
ture oval, occupying rather more than half the length of the zooecium. Margin thin, 
smooth, two slender spines on each side above. A lateral avicularium to each cell and a 
small one in front, below the aperture, and close to the median line of the branch. Ooecia 
shallow, cucullate, wall entire. 
Habitat . — Station 142, lat. 35° 4' S., long. 18° 37' E., 150 fathoms, green sand. Off 
Marion Island, 50 to 75 fathoms. 
I place this form under Menipea, solely on account of the anterior avicularium ; in 
other respects it might as well be referred to the armed group of Cellularia. 
(7) Menipea triseriata , Busk. 
Menipea triseriata, Bk., Brit. Mus. Cat., p. 22, pi. xxiii. figs. 2, 3, 4. 
Character . — Zooecia oblong rectangular (behind), bi- or tri-serial, numerous (twelve to 
fourteen in the internode). Aperture oval, pointed at bottom, and there partially filled
