170 MONOGRAPH OF THE FOSSIL POLYZOA OF THE 



Fam. SPARSIDJE. 

 Cellules not grouped, scattered or regularly spaced. 



ENTALOPHORA. 



Cellules placed all around regular cylindrical or compressed branches. Never more 

 than one layer of cellules, which are regularly placed. Centre of the branches filled 

 with germs of cellules. 



From Clavisparsa this genus is distinguished by being in branches instead of a cla- 

 vate mass. Cavaria was separated by Hagenow on probably a false character. He 

 says that the interior of the branches is hollow or filled with transverse septa?. Meli- 

 certites can be distinguished by the cellules never being tubular, opening usually tri- 

 angular and closed in old cellules, with a testaceous operculum. 



E. quadrangularis, n. s., fig. 58. — Colony composed of quadrangular branches, 

 rounded on the corners. Cellules arranged on the four faces ; bounded below by a 

 prominent lip, in advance, merging into the surface of the branch. Lip emarginate 

 on both sides of the middle, leaving a median labiate projection, sides sloping upwards 

 to the surface of the branch. 



Locality. — Timber Creek and probably near Mullica Hill, N. J. Cretaceous. 



Only two specimens were seen, the largest of which is but -15 inch in length. One 

 of them resembles the Mullica Hill fossils, though it may be, like the other, from 

 Timber Creek. Still, these two deposits are so closely related, if not identical, that 

 it will, in all probability, be found hereafter at both localities. 



E. Coneadii, n. s., fig. 59. — Colony cylindrical, cellules all round, tubular, probably 

 somewhat exsert, arcuate, arranged alternately, separated by distinct depressed lines. 

 The visible portion of each tube is about as long as the transverse width of the branch. 

 The end of the branch shows regular concentric germs of new cellules. We counted 

 three rows in our best specimen. At the origin of a new branch the colony is some- 

 what compressed. 



From near Mullica Hill, N. J. Cretaceous. 



We have seen but two specimens showing cellules as good as the figure and but two 

 more of any sort. There can be no doubt but that the cellules were tubular, from the 

 condition of the remains of the cellules, and they probably extended but little further 

 than the upper part drawn. This has been a handsome little species, and we take 

 pleasure in dedicating it to our friend Mr. Conrad, the pioneer of Tertiary and Cre- 

 taceous palaeontology in this country.
