Description. Zoarium encrusting, consisting of minute, flat- 

 tened, bifurcating and anastomosing branches from .3 mm. to 

 .4 mm. wide in their broadest parts opposite the bases of zooecal 

 groups, the lateral margins converging 1 posteriorly to about one- 

 half that width just in front of the next preceding group of 

 zooecia, the dorsal surface transversely convex. Zocecia fas- 

 ciculate in groups of from, two to five, situated at the summit of 

 tubular processes which rise at nearly right angles from the 

 center of the broadest portions of the zoarium ; in rare instances 

 the erect zooecal processes bifurcate above. 



Remarks. In its habit of growth this species resembles 

 Stomatopora regularis, but it can always be easily distinguished 

 from that species by reason of its fasciculate zooecia. 



Formation and locality. Vincentown limesand, Vincentown 

 (154), Timber Creek (Gabb and Horn). 



Geographic distribution. New Jersey. 



Family LIOHENOPOBIDAE. 



Genus DISCOCYTIS d'Orbigny.

Description. Zoarium more or less irregularly cup-shaped, 

 supported by a very short pedicle with a slightly expanded base, 

 above which the outer surface expands rapidly to its maximum 

 width, which varies from 3 mm. to 7 mm. ; the upper surface of 

 the zoarium marked by strong radiating ridges or lamellae, 

 which usually bifurcate once or twice or branch somewhat irregu- 

 larly. Zocecia small, subcircular in cross-section, the apertures 

 occupying the entire outer surface of the zoarium and the outer 

 extremities of the lamellae of the upper surface; the depressions
