182 CELLULARIIDA. 
GC. carinata, Busk, Voyage of Rattlesnake, Vol. \., p. 363. Cells 
oval, narrowed at each end; lateral processes (without avicularia ?) 
projecting horizontally outwards from the side of the aperture, which is 
nearly central ; mouth with a small tooth on each side, and below it a 
triangular space with three strong conical eminences ; a few scattered 
papille on the surface of the sides and back; ovicelligerous cells gemi- 
nate. 
Netw Zealand (Dr. Joliffe). Bass Strait. 
FAMILY—CELLULARIID:. 
Zoarium divided into distinct internodes by flexible joints ; inter- 
nodes formed by two or more cells in a row; cells disposed in the same 
plane, forming linear branches of a dichotomously divided, phytoid, 
erect, zoarium. 
Genus, CHLLULARIA—Pallas. 
Cells bi-triserial, more than four in each internode; oblong or rhom- 
boidal, contiguous ; perforated behind ; without avicularia or vibracula. 
C. cuspidata, Busk, Zc., p. 19. Upper and outer angle produced 
into a strong spine; a single perforation behind ; a cuspidate spine on 
the summit of the median cell at each bifurcation ; ovicell smooth. 
Lyal’s Bay. Australia. 
C. monotrypa, Busk, Voyage of Rattlesnake, Vol. 1., p. 368. 
Cells oblong, narrowed below, with a single perforation in the upper and 
outer part behind; opening oval, margin smooth; a short spinous 
process at the upper and outer angle; a sharp, short spine in the middle 
of the upper border of the middle cell, at a bifureation ; ovicell (?) in 
form of a very shallow excavation in the upper part of the cell in front. 
New Zealand (Darwin). Bass Strait. 
Genus, MENIPEA—Lamouroux. 
Cells oblong or elongated, attenuated downwards ; imperforate 
behind, sometimes with a sessile avicularium on the upper and outer 
angle ; one or two sessile avicularia on the front of the cell below the 
aperture. 
M. cirrata, Gray, Dieff, N.Z, ii, p. 292. Cells pyriform, con- 
stricted below, six in each internode, one of the lower usually more or 
less aborted ; usually one large lateral avicularium to each internode ; 
three marginal spines very long and strong ; anterior avicularium single, 
its upper border toothed.

M. buskii, Wyv. Thomson, Nat. Hist. Rev, 1858, Q./-AS., 7, 
p. 15t. Cells, elongated, attenuated downwards, three in each inter- 
node; cell-mouth, large, oval, oblique, the lower third filled up by a 
tuberculated calcareous plate ; upper hip prolonged, and fringed with
