Catenicella carinata, Busk, ** Voyage of * Rattlesnake, ” Vol. L., p. 9368. 
“ Cells oval, narrowed at each end; lateral processes (without avicu- 
laria?) projecting horizontally outwards from the side of the aperture, 
which is nearly central. Mouth with a small tooth on each side, and below 
it à triangular space with three strong conical eminences. A few scattered 
papille on the surface of the sides and back.  Ovicelligerous cells gemi- 
nate." : 
New Zealand, Dr. Joliffe. 
Menipea buskii, Wyv. Thomson, * Nat. Hist. Rev.," 1858. 
** Cells, elongated, attenuated downwards, three in each internode. Cell- 
mouth,large, oval, oblique, the lower third filled up by a tuberculated cal- 
careous plate; upper lip prolonged, and fringed with from four to five 
spines, attached to the lip by horny joints, and one of them, usually the 
second from the outer edge, very long, curved, and pod-like. There is often 
an additional spine on the upper and inner margin of the cell mouth. 
Opereulum spine, strong and clavate, stretehing upwards and outwards from 
the lower and inner lip of the cell-aperture. Connecting horny tube be- 
tween the internodes, double.  Ovicell, spherical, with a richly granular 
surface, imbedded among the cells, on the cavities of two of which it 
encroaches.”’ 
New Zealand, Dr. Joliffe. 
Scrupocellaria scrupea, Busk, ** Ann. Nat. Hist.,” 2nd Ser., Vol. 7., 
83 
p. 88. 
** Operculum, reniform, entire, four or five marginal spines above." 
New Zealand, Dr. Joliffe. 
Salicornaria (?) hirsuta, ** Cat. Marine Moll.," p. 91. 
This is identical with Cellaria hirsuta, Lamx. Mr. Busk has made it 
into the type of a new. genus of Salicornariide, under the name of Onch- 
opora. 
OncHopora. 
* Cells, ventricose, coalescent ; not bordered by a raised margin. Ovicells, 
inconspicuous. 
Onchopora hirsuta, Lamx., ** Hist. des Polyp.," cor., p. 126. 
The corneous tubes are not vibracula as I supposed. 
Bugula prismatica, Gray. (Acamarchis.) 
Zoarium rather rigid, compressed, dichotomously branched, erect, red- 
dish-brown. Cells, distant, alternate, cylindrical ; aperture, entire, produced 
into a dentiform angle at the outer margin, from which a keel descends 
obliquely to the inner and lower corner of the cell. Ovarian cells, globular, 
white, situated in a single row on the front of the zoarium. 
Motauau, Canterbury ; and Ocean Beach, Dunedin, [F.W.H.]
