and direction in the study of the class, received from tha 
Rev. J. E. Tenison Woods, naturally induced me to bestow 
that gentleman’s name upon the species. 
Genus, S Kit i a la hi a— LuTnavck. Character: Polypidom 
confervoid, horny, iistular, and branched; cells, tubular, 
uniserial and unilateral, disclosed in close parallel compam s 
in internodes at stated intervals.—Johnston, “British zoo¬ 
phytes,” vol. i. p. 3G8. 
Serialaria Woodsii, n . s. plate III., fig. 5. 
Polypidom of a brown colour, light to dark, horny,, 
fistular, branched, forming dense tufts three 0 ,.°. r 
inches in height; branches alternate, spreading, subdicn- 
otomous towards the extremities; basal tube conugaey 
jointed between the internodes; dells tubulous, biteria, 
unilateral, adnate to each other, gradually shoitei oil - 
wards, apertures thickened, arranged in companies o vo 
to ten pairs on each internode, straight, and much inclined, 
outwards. Two tapering, slender, hollow processes, join e 
to basal tube immediately behind the outer ce s °, , au 
internode; not constant, sometimes a fresh branch taking 
the place of one. These setaceous processes frequently have 
sepUe across them at irregular intervals, and are some lines 
branched. Their length varies much, often three times tno 
length of an internode, sometimes quite short, one. or a pair 
frequently much shorter than its fellow, and sometimes c u - 
shaped. Masses are frequently found cast upon the beach 
without these appendages, as they soon drop on when ea 
Ovicells not seen. The animal has eight tentacles. 
The only species with which it has any 131 
Serialaria Australis, described by Rev. J. L. 
Woods, in a paper read before the Royal Society oi rs.p. W. f 
4th July, 1877, and, like it, has peculiar characteristics, 
notably the fact of the cells being biserial, which wiU 
necessitate a modification of Lamarck's generic description 
given above. , , 
My friend, Mr. Chas. M. Maplestone, was fortunate enough 
recently to find the animal alive, and hopes to obtain it 
again at Portland, so as to be able to make more extended 
observations thereon. He writes me that, on a cursory 
examination, the tentacular crown seemed to arise from a 
calyx, as in the fresh-water polyzoa. A most interesting 
fact, if verified.
