Polyzoa of Queen Charlotte Islands. 41 



Schizoporella hiaperta^ Michelin. 



A specimen has occurred in which the oral avicularia as- 

 sume both the round and spatulate form, as is commonly the 

 case in the allied 8cliizoporella armata^ mihi. 



Schizoporella Dawsoni. 



[See page 20.] 



The species described under the above name I have now no 

 doubt is identical with Escharina torquata of D'Orbigny 

 (' Voyage dans I'Araerique meridionale,' tome v. 4*^ partie, 

 p. 11, =Flustra torquata, Lamouroux). Schizoporella tor- 

 quata must therefore take the place of S. Dawsoni in the 

 Report. I have, however, much pleasure in dedicating a fine 

 species of Tubulipora (which I trust will prove to be unde- 

 scribed) to the able investigator to whom we are indebted for 

 our knowledge of the marine fauna of the Queen Charlotte 

 Islands. 



Schizoporella torquata (D'Orbigny), Lamx. 

 (PL IX. fig. 2.) 



Virago Sound, on shell. 

 [Bay of Hio, on dead shells.] 



Schizoporella linearis, Hassall, form inarmata. 



The only specimens amongst the dredgings which are refer- 

 able to this species are totally destitute of avicularia. In 

 other respects they agree with the typical form, and must be 

 regarded as an unarmed variety. 



[Scandinavia, South Labrador, Mediterranean, Britain, 

 France (S.W.).] 



Family Escharidse (part.), Smitt. 

 Lepralia cleidostoma, Smitt, var. 



A variety of this species occurs which is destitute of avicu- 

 laria. There is frequently a small knob on each side of the 

 orifice, and always a stout mucro immediately below it. The 

 ooecia do not exhibit the strise which Smitt describes, but are 

 smooth and polished. The only specimen, however, which I 

 have examined is strongly calcified and has a highly varnished 

 surface, and in this condition the striae may be obliterated. 

 An Australian variety has already been described with circular 

 instead of pointed avicularia (' Annals ' for August 1881, 

 p. 122).
