NOTE ON NEW OR RARE BRITISH MARINE POLYZOA. 53 



reaches our shores. Although I believe it to be one of the commonest 

 littoral forms in Scilly, I have not found it at Plymouth. 



Mr, Hincks, in his later reference to this species (1887), refers it 

 to the genus Lcpralia. He there states that the " marginal callosity," 

 described by Manzoni (pi. iii. fig. IG), in the specimens from the 

 Italian Tertiaries, is well developed in the specimens from the 

 Adriatic, but that " there is scarcely a trace of it in British examples." 

 This statement is not confirmed by my specimens from Scilly, in which 

 the marginal callosities are at least as well developed, in many of the 

 zocecia, as in those figured by Manzoni. 



4. Schizojyorella cristata, Hincks. (See Brit. Mar. Polyzoa, 1880, 

 p. 254.) 



This is a species described by Mr. Hincks from a single small colony 

 found at Hastings. It is of some interest to record the discovery 

 of two similar small colonies on the inside of an empty valve of 

 Pecten maximus, from twenty fathoms on the Mewstone Ledge at 

 Plymouth.
