I 



Description. — ^Zoarium encrusting, consisting O'f minute, flat- 

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

 .4 mm. wide in their broadest parts gp'posite the bases of zooecal 

 groups, the lateral margins converging posteriorly to about one- 

 half that width just in front O'f the next preceding group of 

 zooecia, the dorsal surface transversely convex. Zooecia 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 oi growth this species resembles 

 Stomaiopora regularis, but it can always be easily distinguished 

 from that species by reason oi its fasciculate zooecia. 



Formation and locality. — Vincentown limesand, Vincentown 

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



Geographic distribution. — New Jersey. 



Family LIOHBNOPORIDAB.

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. Zooecia 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
