Many of which_, Mr. Alder observes, are generally rare or 
wanting in the south and west. Comparing the marine Fauna 
of the above region with that of the south coast, the most 
striking deficiency is found in the Asteroid and Helianthoid 
orders, many genera in which are entirely wanting ; as are 
likewise all the calcareous and corticated corals. Of the more 
conspicuous south country zoophytes we may note the absence 
of — 
Sertularia nigra. 
pinnata. 
Plumularia pennatula. 
Campanularia gelatinosa. 
Anthea cereus. 
Adamsia palliata. 
CaryopJiyllia Smithii. 
And, among the Polyzoa, of — 
Memhranipora Lacroixii. 
Flnstra cliartacea. 
Caberea Boryi. 
Valkeria pustulata.
