 ?Lepralia Peeugiana, Hdler, Bryoz. Ad. M. 26, pi. ii. fig. 10. 



Zocecia ovate, distinct, separated by moderately deep 

 sutures, lined round, quincuncial, thickly punctured 

 over the surface, with a smooth central umbo ; orifice 

 arched above, lower margin straight, with a loop-like 

 sinus in the middle; peristome slightly thickened. 

 Ooscia globose, prominent, minutely granular, of a deli- 

 cate pearl-whiteness. Aviculaina none. 



Colonies spreading irregularly, vitreous and glistening 

 when fresh. 



Range of Variation. There is very little variability in 

 this handsome species ; but it seems to be very liable to 

 monstrosities. The ovicells are commonly distorted and 

 bent out of their natural position. Abnormal cells also 

 frequently occur, of great width and irregular shape, 

 formed evidently by the union of two cells. 



Habitat. On stone, shell, &c, from rather deep water. 



Localities. Jersey (Mrs. Buckland) : coast of Cornwall, 

 on stone, &c., from deep water; Guernsey (T. H.). 



Geographical Distribution. Algiers (J. Y. J.) : ?Adri- 

 atic (Heller) : Naples (A. W. "Waters) : Australia (Miss 

 Jelly). 



* Savigny's figure is admirable in most respects ; but the artist has repre- 

 sented a granular instead of a punctured surface.
