Description. Zoarium incrusting. Zooecia arranged in quin- 

 cunx and in radiating lines from a central group of two> or three 

 zocecia which are somewhat smaller than the rest although per- 

 fectly developed in all their structural details ; form of the zooecia 

 oval, elongated, convex, slightly more elevated at the distal than 

 at the proximal end, separated from each other laterally by dis- 

 tinct depressed lines produced by the meeting of the convex 

 surfaces, and anteriorly by the elevation of the distal extremity 

 above the proximal extremity of the succeeding zocecium. 



Zocecial apertures rounded-subquadrate to circular in outline,, 

 bordered by an abrupt but little thickened lip which also encircles 

 the avicularia. Avicularia rather large, generally elongated 

 longitudinally, often narrowed at their anterior extremity, situ- 

 ated one about midway upon either side of each zocecial aperture. 

 Ovicels numerous, small, subglobular, rounded anteriorly and 

 emarginate at the border of the zocecial aperture. 



Remarks. This is a rare form which has not been met with 

 in the recent collections, but its characters seem to be sufficiently 

 distinct to admit o<f its easy recognition in case it is met with in 

 future collections. 



Formation and locality. Vincentown limesand, near Mullica 

 Hill (Gabb and Horn). 



Geographic distribution. New Jersey.
