Diagnosis : 
Zoarium hippothoiform: uniserial; branches crowded and 
irregular; entirely adherent. Zooecia pyriform : long 
slender proximal ends; front wall well raised, rounded, 
and punctate; orifice small, circular, surrounded by a low 
rim. Peristomial area slightly raised; flat regular rims 
surround each of the zooecia. 
Distribution : 
Adherent to Cardium citrinoidum. Cornbrash, near Scar¬ 
borough. Only the type specimen known. 
Affinities : 
The species agrees best among Jurassic species of the genus 
in its pyriform zooecia with S. dichotomoides (D’Orb.), 
but the hippothoiform zoarium and long whip-like 
proximal portions of the zooecia clearly distinguish it. 
Owing to the imperfection of Phillips’ figures, much 
uncertainty has existed regarding it; the accompanying 
figure has therefore been prepared. The front walls are 
often broken away, giving the specimen a Schizoporellidan 
aspect. 
Family : Diastoporidae. 
Genus: Berenicea. Lamoroux, 1821. 
[M. Sauvage (Bry. Juras. Boulogne; Bull. Soc. Geol. France; 
ser. 3, t. xvii., 1888, p. 43) accepts Roemer’s genus Rosacilla , as 
Berenix was in use before Berenicea was proposed : the two names, 
however, seem to be quite sufficiently distinct to render the 
change unnecessary.]
