of the beak, and is bounded posteriorly by a deep triangular pit, and ante- 

 riorly by a shallower and narrower one. Nothing further is clearly known in 

 reference to the hinge. The shell seems to be thick and externally smooth. 



Length, 1-72 (100) ; height, 1-13 (66) ; convexity of one valve, '34 (20); 

 distance from beak to anterior extremity, "55 (32); to posterior extremity, 

 1 21 (70). 



Collected at Battle Creek, Michigan, by A. W. 



Resembles S. similis, Win., but differs in more prominent beak, greater 

 convexity and straight ventral margin. 



Sanguinolaria similis, Win., occurs at Napoleon Cut, Jackson county, 

 Michigan. 



CONULARIA, Miller. 



Conularia Newberryi, n. sp. Shell very small, in the form of a quadran- 

 gular pyramid, (the apex of which has been broken off in the specimen de- 

 scribed.) The pyramid is inclined over one of the angles. Angles of the 

 pyramid slightly rounded, and marked by a shallow groove running longitu- 

 dinally. Each side is marked by sharp, raised, transverse lines, which, in- 

 stead of running directly across, are angulated in the middle, so that at this 

 point they are nearer the base of the shell by a distance equal to once and 

 a half the distance between two lines. The distance between the lines in- 

 creases from above downwards, and is everywhere equal to about one-ninth 

 the width of the side. These transverse lines have the appearance of the pro- 

 jecting e'lges of septa, and are continuous from the middle of one of the 

 shorter sides of the pyramid around to the same point, though the ends do 

 not join but alternate in position. The sides of the pyramid are inclined at 

 an angle of 30, and, if they met at a point in the perfect specimen, it must 

 have been about half an inch in length, with a width at base of about '17 

 inch. 



Collected by A. Winchell, at Cuyahoga Falls, Ohio, in the water limestone 

 below the conglomerate. 



Named in honor of Prof. J. S. Newberry, M. D , equally distinguished in the 

 service of science and of his country. 



BELLEROPHUN, Montfort. 



Bellerophon Whittleseyi, n. sp. (" Goniatitfi," figs. 1 and 2, Whittlesey, 

 Proc. Amer. Assoc. Cincin., p. 219.) Shell rather large, globoid, rapidly en- 

 larging, umbilicus moderately large, exposing one anterior whorl. Trans- 

 verse section triangularly and broadly lunate, the dorsum being slightly ele- 

 vated, and the dorso-lateral slopes slightly flattened; greatest diameter of 

 section near the umbilicus. Keel rather distinct but with an indistinct band. 

 Surface marked by raised, rather distant striae, which emerge from the umbi- 

 licus with a slight backward inclination, and, curving forwards, pursue a 

 course directly across the lateral surfaces for two-thirds the distance from the 

 lateral to the dorsal angle, where they undergo a sudden deflection back- 

 wards, making with themselves very nearly a right angle, and forming on the 

 dorsum, by the meeting of opposite branches, a retral angle of 45. Sinus 

 not seen, but probably triangular and broad. 



Greatest diameter of whorl, *87 ; dorso-ventral diameter of aperture, '57 ; 

 number of striae in one-tenth of an inch, near the aperture at the point where 

 they turn backwards, 3 to 3J. 



This species resembles B. rugosiusculus, Win., in general features, but 

 lacks the longitudinal decussating striae. It may be distinguished from all 

 related species by the peculiar geniculation of the striae in the dorso-lateral 

 region. 



One mile east of Orange Center, Cuyahoga county, Ohio, 20 or 30 feet below 

 the grindstone grit. Whittlesey's collection.
