and Cauda repUma (li.). Development described and discussed by 
IbuTois, 1. 0 . pp. 178-103, pi. x; tlmt ol’ Bugula Jlabellata and BiccUaria 
ciliata also by Joliet, Arch. Z. expdr. vi. pi. viii. figs. 1-4, 8-11. 
Bugula avicularia (L.). Its colonies do not pass the winter ; Joliet,

CELLULARIID.a!l. 
Scrupocellaria. Hi N OKS states that in /S. reptans two sorts of root-like 
projections are to be found, one terminating in a disk, fixed by adhesion 
to foreign objects, the other having hooked, anchor-like ends for fixation 
on Ilydroids or Sponges; Ann. N. II. (4) xx. pp. 218-220. This has 
been observed in S. scruposa (L.) by Peach, Nature, June, 1877. On the 
development of the same, see Barrois, 1. c. p. 178, pi. iii.

Arch. Z. exper. vi. p. 280, pi. viii. fig. 12, pi. ix. figs. 1-3. 
SALICORNARIIDiE. 
Salicomaria farciminoides (Ellis) and sinuosa (Hassall). Their identity 
confirmed by Joliet, 1. c. p. 287. 
MEMBRANIPORIDiE. 
T. Hincks, Ann. N. H. (4) xx. pp. 520-529, proposes a new classifica- 
tion of the British species of this family, regarding chiefly the form of 
the zocecia. He restricts the genus Lepralia (Johnst.) to the type of L. 
pallasiana (Johnst.) ; admits Memhraniporella (Smitt), type Lepralia 
nitida (Johnst.), Cribrilina (Gray), type L. radiata (Moll.), Eschar ella 
(Smitt), type L. reticulata (Macg.), Anarthropora (Smitt) restricted, type 
L. monodon (Busk), Micropora (Gray), containing Membranipora coriacea 
(Esp.) and L. complanata (Norm.) ; and proposes the following new 
genera : — 
Mucronella. Inferior margin of the aperture mucronate, a denticle 
within. Type, Lepralia peachi (Johnst.) ; p. 526. 
Microporella. Inferior margin of the aperture straight and entire, a 
semiluuate or circular pore below it. Type, L. ciliata (Pall.) ; p. 526. 
Mastigophora. Inferior margin of the aperture straight, with a central 
sinus ; one or more lateral vibracula. Type, L. hyndmanni (Johnst.) ; 
p. 527. 
Schizoporella. Inferior margin of the aperture with a central sinus ; 
avicularia usually lateral, sometimes median, with an acute or rounded 
mandible. Type, L. unicornis (Johnst.) ; p. 527.
