214 NORMAN, ON RARE BRITISH POLYZOA. 



ternata, forma duplex, but differs from it in the presence of 

 the oral spines and operculum, and the absence of well- 

 marked lateral avicularia. As I cannot regard the form 

 figured by Smitt as a variety of M. ternata, and it seems 

 desirable to point out the distinguishing characters which 

 separate it from its allies, I draw up the following descrip- 

 tion from the figures referred to, and name the form after its 

 discoverer. 



Menipea Smittii, n. sp. [not British). 



Menipea ternata, y,foi'ma duplex, Smitt. Ofversigt af K. Vet. 



Akad. Foi-han., 1867, p. 



283, pi. xvi, figs. 25, 26. 



Cells in a double row, as many as twelve to an internode, 



elongated ; oral aperture ovate, not furnished with spines or 



operculum. A lateral avicularium of moderate size, and also 



a small suboral avicularium in front of each cell. 



Found by Malmgren in 50 fathoms, at Spitzbergen, in 

 1861.

The ovicells in this species, which had not apparently been 

 seen by Busk, are imperforate ; and in this respect the spe- 

 cies differs from the Crisia pilosa, Audouin (Saviguy, 

 ' Egypt,' pi. xii, fig. 1), to which, in its other characters, it is 

 closely allied.
