ZOOPHY'TOLOGY, 
AMONGST numerous specimens of Polyzoa and Sertularians, 
chiefly from the Cape of Good Hope and Australia, with which 
we have been lately favoured by Mrs. Gatty and by Miss E. 
Gore, are many new species, which we hope to be able in 
due course to describe. On the present occasion we give 
four of these. 
I. Class—Ponyzoa. 
Sub-Order 1. Cnrrmmostomata. 
Fam. 1. BiceLLartap#, Busk. 
Gen. Bugula, Ok. 
B. cucullata, nu. sp. Pl. XXXVI, figs. 1—6. 
Cells biserial, elongate, subpyriform ; aperture occupying about two thirds 
of the length of the cell; a short spine at each upper angle, and a smaller 
one on the outer margin a little way below the angle; ovicell very shallow, 
cucullate, or saucer-shaped ; avicularia sparse, affixed usually on the outer 
side of the cell. 
Hab. Australia, Miss Gore ; Western Australia, Mrs. Gatiy . 
The polyzoary of this pretty species is white. It appears 
to attain several inches in height, the branches being short 
and fan-shaped. In general habit and mode of growth it 
closely resembles B. avicularia, from which, in fact, it is dis- 
tinguished chiefly by the peculiar saucer-shaped form of the 
ovicell, and the extreme rarity of the avicularia, which organs, 
however, are, as usual in the family, of the capitate form. 
Fam. 2. FrustRipa&. 
Gen. Chaunosia, n. gen.* 
Cells sejunct, attached apparently only by long tubular fibres. 
C. hirtissima, n. sp. P 
Cells ovate, elongate, suberect, very convex behind; aperture occupying 
the whole front of the cell; mouth at the summit, cresentric above, border 
simple; margin of the aperture and the entire surface of the cell behind 
* yatvos, larus,
