The species described under the above name I have now no 
doubt is identical with LEscharina torguata of D’Orbigny 
(‘ Voyage dans Amérique méridionale,’ tome v. 4° partie, 
p- 11, =flustra torquata, Lamouroux). Schizoporella tor- 
guata must therefore take the place of S. Dawsoni in the 
Report. I have, however, much pleasure in dedicating a fine 
species of Yubulipora (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.

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.

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 
ocecia do not exhibit the strie 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).
