PlIILLIPSASTREA AFFINIS. (N. sp.) 



Descripiio7i. — Corallum in the form of lenticular masses or colonies, 

 composed of corallites of from six to eight lines in diameter, closely com- 

 pacted together so that the divisions between them are only obscurely 

 distinguishable. The cups of these corallites are indicated by a number 

 of circular pits in the upper surface of the corallum. They are 

 nearly three lines in diameter and two lines in depth, their walls vertical, 

 or nearly so, a small rugose elevation in the bottom. From the margin of 

 each of the cups, about forty septal striae radiate to the division lines 

 between the corallites. The septal ridges between the striae are angular 

 and minutely serrated or denticulated along the sides, and apparently 

 along the crests. The striae are also crossed by minute transverse 

 thread-like lines, about six in the width of one line. These characters 

 cannot be seen unless in those places where the surface is perfectly pre- 

 served. In general the rays only appear as so many small ridges, 

 somewhat rugose in aspect. 



The corallites are five, six or seven sided, and the divisions between them 

 are indicated either by small elevated rugose lines, or by the angle formed 

 by the meeting of the septal striae. The margins of the cups are some- 

 times slightly elevated above the general surface, but often are even 

 therewith. The distance between the cups is usually five or six lines 

 sometimes seven or eight lines. 



This species is closely allied to P. VerneuU (Edwards and Haime)* but 

 has somewhat longer corallites, and the margins of the cup not so 

 much elevated. 



Locality and Formation. — Indian Cove, Gasp6, in the Gaspe lime- 

 stone, No. 8.

POLYZOA. 

 PoLYPORA? Psyche. (N. sp.) 



Description. — This species occurs in the form of large undulated 

 expansions, with the longitudinal stems branched and converging in one 

 direction. When perfect, it appears to have been infundibuliform, 

 more or less conical at the base ; but, above, with the margin, and at 

 least the upper half, expanding and curving outwards. Large specimens 

 appear to have formed a cup about five inches in height, and the 

 same in width across the expanded margin.
