BERENICEA. 83 



Among the species with irregular zoaria it must be compared 

 with B. compressa (Goldf.). With this it agrees in the length of 

 its zooecia, their faint punctulation, and the slight expansion just 

 below the raised portion of the aperture. The species differ, how- 

 ever, in the greater distance of the apertures in the old species, 

 and their very irregular distribution. One has only to compare 

 the crowded regular quincuncial orifices of B. sauvagei with Vine's 

 figure (op. cit. pi. xix. figs. 3 and 7) to see the extent of this 

 difference.

Affinities. This species greatly resembles Haime's figure of 

 Berenicea striata (Bry. jurass. pi. vii. figs. 8a-b), owing to the 

 transverse ribbing. The two species are closely allied ; thus 

 B. striata has a formula of 1, 1, 2, /O. The differences between 

 the zooecia of the two species are, that those of B. striata, have
