OS FOSSIL POLYZOA. 109 



character of C. sinuosa. In the same specimen, before any ovicells are 

 formed, the aperture is very near the top of the zooecium ; but afterwards 

 its position is near the centre. Having found the position of the aperture, 

 the shape of the ovarian opening, the shape of the zooecium and of the 

 bordering rim unsatisfactory characters, there only remained the avicu- 

 laria ; and in all the specimens I have examined I have found one form 

 constant. The 0. fistulosa from the Mediterranean has its rounded 

 avicularium above the zooecium ; the C. sinuosa has a diagonal aviculariuin 

 pointed downwards, with the lower part raised ; the C. Johnsoni, from 

 Rafallo, Italy, and New Guinea, has a zocecial avicularium with a project- 

 ing hood above, as figured by Hincks. I find my observations on the recent 

 species entirely confirmed by the examination of a large number of fossil 

 forms.' It is very evident from this, that of the whole of the synonyms 

 given below from Reuss and others, many still merit re-examination, and 

 it must be remembered that in giving them from these respected authors, 

 I give them upon their authority only. Of course Mr. Waters's synonyms 

 may be taken as evidence of work along the lines which he himself has 

 laid down.

 Localities. — Living, widely distributed. Fossil : Mount Gambier, 

 common ; and also from the Pliocene and Miocene of Europe. ' But as 

 we cannot be quite sure of the descriptions of Reuss and others, that 

 Salicornaria jarciminoides does not include other species, it is best to 

 refrain from giving localities.' — Waters.
