Zocecial apertures circular, tubular and inclined a little forward in 

 unworn specimens.''" Weller. 



The type specimens were obtained from the Vincentown limesand of 

 the Eancocas formation of New Jersey, where the species occurs quite 

 abundantly.

 Creek between mill-dam and Odessa, and at Xoxontown Millpond, Dela-

Stomatopora kiimmeU Ulrich and Bassler, 1907, Geol. Survey of New Jer- 

 sey, Pal., vol. iv, p. 314, pi. xx, fig. 4. 



Description. Zoarium encrusting, ramose, the branches very fine 

 and delicate, from 0.15 mm. to 0.2 mm. in width, the surface transversely 

 convex, the slope from center to lateral margins never abrupt. Zooecia 

 regular in form, scarcely differentiated, although the sides converge 

 slightly posteriorly. ZocEcial apertures circular, in unworn specimens, 

 with the rim slightly elevated and inclined a little forward. 



This species is a very close ally of S. regularis, but may be distinguished 

 from that species by its more delicate growth and smaller zooecia. 



Occurrence. EANCOCAS FORMATION. Noxontown Millpond, Delaware.
