attached to the side of it, sometimes to the top also, as if to 

 shield it from some danger. But we must have more definite 

 knowledge than we now possess of the function of the avicu- 

 laria themselves before we are likely to determine the precise 

 office of the subsidiary appendages. It may be noted that 

 the extremity of these curious organs is commonly bent 

 downwards from a definite point. 



I do not propose to discuss at any length tlie generic posi- 

 tion of this very interesting form. It possesses characters 

 which, I think, should separate it from Memhranipora, and 

 may probably be referred to the genus Farcimia of Pourtales*, 

 of which Smitt, in his ' Floridan Bryozoa' (part ii. p. 3), has 

 given an interesting account, pointing out its distinctive 

 peculiarities. The generic name, as he has remarked, was 

 originally given by Fleming to a Cellaria, and is therefore a 

 more synonym available for further use.

 ScMzoiJorella cinctipora^ sp. n. 



Mr. Waters has described and figured a variety {personata) 

 of this species t from New Zealand Tertiary beds. The 

 differences, however, between the supposed varietal form and 

 the recent S. cinctipora as figured seem to be so striking and 

 important that I venture to question their specific identity.

Lepraliaforaminigeray sp. n. 



This species has also occurred in the New Zealand Tertiaries. 

 Mr. Waters notes that only the two upper openings in the 

 cell-wall occur in fossil specimens. 



Ibid. (p. 110 Sep.). 



Lepralia rectilineata^ sp. n. 



This has also been found fossil in New Zealand. Waters 

 mentions that there is " often a small ridge or boss at each 

 side of the aperture, just below which there are two small 

 avicularia." The ocecium, which I had not met witli, is 

 described as " raised, globular, about half as wide as a 

 zocecium."
