3 H CRETACEOUS PALEONTOLOGY. 



Formation and locality. Vincentown limesand, Vincentown 



(154). 

 Geographic distribution. New Jersey. 



Stomatopora kummeli Ulrich and Bassler n. sp. 

 Plate XX., Fig. 4. 



Description. Zoarium encrusting, ramose, the branches very 

 fine and delicate, from .15 mm. to .2 mm. in width, the surface 

 transversely convex, the slope from center to lateral margins 

 never abrupt. Zocecia regular in form, scarcely differentiated, 

 although the sides converge slightly posteriorly. Zooecial 

 apertures circular, in unworn specimens, with the rim slightly 

 elevated and inclined a little forward. 



Remarks. This species is a very close ally of S. regularis, but 

 may be distinguished from that species by its much more deli- 

 cate growth in every way.

Stomatopora temnichorda Ulrich and Bassler n. sp. 

 Plate XX., Figs. 5-6. 



Description. Zoarium adnate, frequently branching, con- 

 consisting of uniserially-arranged zocecia. Zocecia elongate-pyri- 

 form, or club-shaped, .45 mm. to .75 mm. in length, about .02 

 mm. in width at the posterior extremity, increasing very grad- 

 ually in size through about one-half their length, and then some- 

 what abruptly to about .15 at the rounded anterior end. Zocecial 

 aperture nearly terminal, small, circular, with a slightly elevated, 

 rim-like border, from .035 mm. to .05 mm. in diameter. 



Remarks. This exceedingly delicate little species belongs with 

 a group of forms typified by S. inilata of the Ordovician faunas. 

 It may be readily recognized by its exceedinly fine and elongate 

 zocecia.
