[Genus MENIPEA (Lasix.). (Sub-kingdom MoUusca. Class Polyzoa. Order Infun- 

 dibulata. Sub-order Cheilostomata. Family Cellularidse.) 



Gen. Char. — Zoarium articulate or (in one species) continuous. Zooecia bi-raultiserial, 

 oblong, imperforate behind. A sessile, lateral avicularium (frequently absent), and one or two 

 sessile avicularia (also frequently absent) on the front of the zooecia. No vibracula.J 



Description. — Zoarium continuous, dichotomously branched; branches narrow, 

 bordered by radical fibres springing- from the lower part of the back of the cells. 

 Zooecia multiserial, elongated, aperture large, elliptical, with a slightly thickened 

 margin, and overlapped by a large sacculated fornix ; the marginal zooecia with three 

 spines at the outer angle and one at the inner; the central with a single spine at 

 each side. A sessile avicularium (usually al)sent) attached to the upper and outer 

 angle of the lateral zooecia ; a sessile avicularium on the front of each zooecium, 

 except the marginal, usually close to the peduncle of the fornix of the adjoining 

 zooecium. Zooecia posteriorly quadrate, smooth or faintly longitudinally sulcate. 

 Ocecia prominent, rounded, smooth.
