Genus Diporula, Hincks. 



Distinguished from Microporella by the structure of the orifice. The 

 genus is founded upon a single species, Diporula (Eschara) rerrucosa, 

 Peach. Mr. Hincks cites as a synonym E. Jiinariti, Waters.

' Zoo'cia more or less distant, connected by a tubular network ; tlw) 

 oritice semicircular, with the inferior margin entire; the special poro

 Audonin. In his description of Lepralia Brongniartii, And. (' Bay of 

 Xap. Bry,' p. 35, 'Ann. M. N. Hist.') Mr. AVaters says the 'connections 

 between the zooocia arc short tubes as shown in Savigny's tig. . . . 

 This is interesting as showing the first step towards more widely 

 separated cells, lite Diachoris : and Hutton calls a form closely allied to
