Polyzoa of Queen Charlotte Islands. 57 
along with Phylactella lucida mihi, a Madeiran species (see 
‘Annals’ for July 1880), and a kindred form from the Queen 
Charlotte Islands, which I shall now describe. 
Lagenipora spinulosa, n. sp. (Pl. III. fig. 4.) 
Zowcia lageniform, rather irregularly disposed, the lower 
portion adherent, ovate, thickly covered with punctures (some- 
times almost obliterated, when the surface appears roughened 
or subgranulous) ; the oral extremity free, tubular, much pro- 
duced, suberect, the surface perfectly smooth and subhyaline, 
slightly expanded upwards ; orifice terminal, suborbicular, the 
front margin plain or trimucronate, and more or less elevated 
above the rest, somewhat everted, on each side a raised process 
bearing a small avicularium of the Scrupocellaria type, with 
minute pointed mandible directed outwards, on the upper (or 
hinder) margin several spinous processes. Occium small, 
rounded, smooth, placed far down at the back of the tubular 
portion of the cell. 
Zoartum forming small lobate patches. 
On Tubulipora (especially) and shells ; not uncommon. 
This form is nearly related to Z. lucida, mihi, but is, I have 
no doubt, distinct. ‘There is a marked difference between the 
avicularia of the two species. In JZ. spinulosa there are 
two, one on each side of the orifice, resembling very closely 
the form which is characteristic of the genus Scrupocellaria. 
In L. lucida there is only a single minute, oval avicularium, 
which is borne on a stout process, in the centre of the lower 
margin. JL. spinulosa is altogether stouter in habit than the 
Madeiran species, and in the normal state the adherent portion 
of the cell is thickly punctured, whereas it is entire and smooth 
and subhyaline in the latter. It differs from Z. lucida in 
another point. On each side of the free tubular portion of the 
cell there is a very distinct line, running the whole length of 
it, which seems'to mark the junction between the front piece 
and the rest of the tube. The strongly marked groove at the 
base of the neck-like extension in L. /ucida is wanting in the 
present form, which is also characterized by a peculiar habit 
of growth. ‘ 
Microporella Malusi’, Audouin. 
A variety of this species occurs, in which there is a very 
prominent umbo below the pore.
