The Vicentine specimens may be taken as fairly typical, M. Du- 

 merilii having two avicularia above the ovicell, and zooecia without 

 an ovicell, having either one or two avicularia. This is very similar 

 in. shape to M. appendiculata, but is much smaller, the opesia being 

 only about 0*35 millim. long. I described a fossil from New Zealand 

 (Quart. Journ. Geol. Soc. vol. xliii. p. 45) as 31. Dumerilii, although 

 somewhat divergent from the type.

A colony from Brendola has a slightly raised small hood-like 

 ovicell. There are a few zooecia (fig. 1 a) nearly double the width 

 of ordinary zooecia, and they cannot be considered ovicelligerous, 

 seeing that there are ovicells; but perhaps irregularities on the 

 surface on which they are growing has caused this difference in 

 size. There are, besides, in some specimens raised giant zooecia, 

 occupying about the space of three zooecia. As the living M. Eos- 

 selii is pretty regular, perhaps we should call this var. deplanata.
