hy Ronss, Giibb ancl JTorn, and Roomer. Tiio list is thcreforo, for tlio 

 present, a compilation rather than the result of special work, and it may 

 in tlio fntnro have to bo modified. The recent sj)ecies are very few, and 

 their range is limited. In the JJritisli seas oidy one is recorded ; in the 

 ]klediterranean Mr. Watei-s records threo .species, and as these have fossil 

 representatives as well as recent, i cfivc^ Mr, Waters's list first — 'Bry.

Tiie Diastoponx! of the Tertiary i-ocks, even as defined above, which 

 include the foliaceous forms, are not abundant. So many difi[erent forms 

 liave been included in the group that it is difficult frcmi the lists to say 

 wliii.'h are true Diastopoiw and which arc not. The following, however, 

 are the identifications of two of our best workers on Recent and Tertiary 

 species ; so the synonyms may be relied on as beinti- tolerably correct.
