tETEA recta (Hincks). 



[Genus jETEA (Xamx.). (Sub-kingdom MoUusca. Class Polyzoa. Order Infundibulata. 

 Sub-order Cheilostomata. Family JEteidse.) 



Gen. Char. — Zocecia arising from a creeping or partially free stolon which is dilated at 

 intervals, tubular, with a subterminal membranous aperture. No avicularia or ooecia.] 



Description. — ZocBcia rising from large inflations of a creeping stolon, erect, 

 truncated, upper portion straight and not enlarged; aperture long, lateral; lower 

 part of zooecium finely ringed, the rings ceasing immediately above the commence- 

 ment of the aperture, the upper part being finely punctate.

Readily distinguished from the other species by the erect, 

 straight habit, the truncated extremity, the upper part being 

 scarcely if at all dilated, and the length of the aperture, which is 

 about a third of that of the whole zooecium. I see no reason for 

 considering this as a variety of ^. anguina, as has been done by 

 some writers.

SCRUPARIA CHELATA (Linn. sp.). 



[Genus SCRUPARIA (Oken). (Sub-kingdom Mollusca. Class Polyzoa. Order Infun- 

 dibulata. Sub-order Cheilostomata. Family Eucrateida;.) 



Gen. Char. — Zoarium composed of tufts springing from a creeping, adherent base ; branches 

 originating from the front of a zooecium, below the aperture. Each zocBcium arising from the 

 preceding by an articulated tube at the upper and posterior part.] 



Description — Zocecia glassy, horn-shaped, very narrow below and widened 

 above, aperture very Lirge, oblique, truncated above, with a distinct raised, smooth 

 margin, usually an aborted zooecium below the aperture.
