ESCHARID^E : RETEPORA. 353 



between them is punctulated. Other parts are rough, from a short 

 mucro that projects over the mouth of the cells, and these are pro- 

 bably the mature and perfect cells. Height of specimen, three- 

 fourths of an inch ; breadth, nearly the same. 



I cannot refer this to any species described by Milne-Edwards in 

 his monograph of the genus. It approaches nearest to E. porosa. 



I have seen fragments of other two native species of Eschara one 

 from Scarborough in the collection of Mr. Bean, and another from 

 Zetland which was sent to me by Professor E. Forbes ; but they 

 were too imperfect to be described with the minuteness that is neces- 

 sary in so difficult a genus.

 " Expanding to the extent of two or three inches ; more or less 

 cup-shaped, waved, uniting; the lobes are oval, regular, the inter- 

 vening spaces supporting two or three pores in oblique rows. This 

 species is very distinct from the R. cellulosa, with which it has been 

 confounded." Fleming.
