getlier, except on the peduncle of the tail. The fins partake of the color of 

 the region to which they belong, and exhibit irregularly shaped spots on each. 

 These markings on the fins are very variable, and in some specimens are 

 wanting. A very deep glossy black circular spot, above the angle of the oper- 

 cle, marks the beginning of the lateral line, which is only apparent on a very 

 careful examination. Total length, 15 inches ; greatest width, 5^ inches. 



This species is possessed of a gizzard similar to that of C. ellipticus 

 Kirtland ; to which species this bears considerable resemblance, yet is very 

 distinct in its general form, color and habits. 



The specimens of this fish, from which the description was taken, I pro- 

 cured in a secluded and very deep sheet of water, known as the "Sturgeon 

 Pond," situated two miles below Trenton, N.J. The following items of its 

 habits were collected from reliable fishermen and by my own observation. 

 This fish is remarkably gregarious, and is never seen associating with any 

 other than its own species ; it is a lover of deep and still water, seldom rising 

 to the surface, and appears very averse to the bright light of the sun. If 

 driven into a stream of water with considerable current, they immediately 

 show signs of uneasiness, and, if not soon liberated, die. Two localities only 

 I am acquainted with that abound with this species, and both are deep small 

 lakes formed by the junction of several small streams, and never in these 

 streams has the fish been discovered, except when driven into them by the 

 fishermen. As an article of food they are entirely worthless ; yet they afford 

 much sport to juvenile anglers, by the rapidity with which they may betaken, 

 with a trout-fly, or common angling worm. 



Descriptions of new Cretaceous Corals from New Jersey. 

 BY WM. M. GABB AND GEO. H. HORN. 



Hippothoa irregularis . Colony spreading, on shells, forming straight, 

 cr but slightly curved lines ; branching nearly at right angles, though gene- 

 rally from but one side of the cell. Cells oval, flattened, placed closely 

 together, united by a stout pedicle. Opening nearly central, with its greatest 

 diameter in the direction of the length of the cell, often with an ovarian 

 vesicle at the distal extremity. 



The shape of the cell of this species relates it nearly to the H. simplex 

 D'Orb. 



Cellepora b i 1 a b i a t a . Colony encrusting, generally in elongate patches. 

 Cells in lines arranged in an irregular quincunx, convex. Opening, viewed 

 from above, nearly circular. The cell walls above and below the mouth pro- 

 ject, forming two labiate processes. 



Cellepora car in at a. Colony encrusting. Cells in quincunx. Walls of 

 cells meeting anteriorly, forming a carina, whose apex projects forward, and 

 toward the oral opening, apex often perforated.*" Carina diminishing as it 

 approaches the cell below. 



Cellepora t y p i c a . Colony encrusting, in large patches. Cells arranged 

 in radiating lines, usually in quincunx, irregular exteriorly, small, rhom- 

 boidal, spaces between oral openings wide, perforated by numerous large 

 accessory foramina. 



This specimen was found encrusting a Terebratula H a r 1 a n i, to which was 

 also attached an Ostrea panda, both being typical specimens. 



Reticulipora s a g e n a . Colony large (about one inch in diameter), formed 

 of plates, lateral plates not numerous, given off rectangularly ; summit of 

 plates perforated by cells, and thicker than the rest of the plate ; lateral open- 

 ings triangular, without any marked arrangement.
