Polyzoa of Queen Charlotte Islands. 31 



* 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.) 



Zooscia 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 aviculariiim of the Scrupocellaria type, with 

 minute pointed mandible directed outwards, on the upper (or 

 hinder) margin several spinous processes. Ooecium small, 

 rounded, smooth, placed far down at the back of the tubular 

 portion of tlie cell. 



Zoarium forming small lobate patches. 



On TuhuUpora (especially) and shells ; not uncommon. 



This form is nearly related to L, lucida, mihi, but is, I have 

 no doubt, distinct. There is a marked difference between the 

 avicularia of the two species. In L. 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 aviculariura, 

 which is borne on a stout process, in the centre of the lower 

 margin. L. 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 L. 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. lucida is wanting in the 

 present form, which is also characterized by a peculiar habit 

 of growth. 



Microporella Malusii, Audouin. 



A variety of this species occurs, in which there is a very 

 prominent umbo below the pore. 



Schizoporella biaperta, Michelin. 

 In a variety of this widely distributed species from the
