Locality. Discovered by Capt. Bowman, U. S. A., in the sands of Ashley 

 river, South Carolina. 



8. Pogonias. Numerous isolated teeth of this genus, of the same form and 

 size as those of the recent Pogonias chromis, were discovered by Capt. Bowman 

 with the preceding in the sands of Ashley river. 



9. Sphyr^na major. Based upon numerous specimens (more than a hundred) 

 of isolated crowns of teeth, the smallest of which measures 3 | lines long and 2.] 

 lines wide at the base, and the longest 8h lines long by 4| lines wide at the base. 



Locality. Discovered by Capt. Bowman in the sands of Ashley river, South 

 Carolina. 



16. Enchodus ferox. Sphy/csna, Morton : Syn. Org. Rem. Cret. Group of the 

 U. S., PI. xii. fig. i. Based upon specimens in the Cabinet of the Academy, 

 consisting of fragments of the jaws with teeth, which have usually been referred 

 to the genus Sphyrcena, but to this they do not belong, as the teeth are not in- 

 serted in sockets, but are implanted by expanding roots co-ossified with the 

 surface of the jaws, 'lhe specimens consist of an isolated anterior tooth (repre- 

 sented in Morton's PI. xii. fig. 1), of a portion of the left intermaxillary bone with 

 the anterior tooth, which measures If inches in length from its base of attachment: 

 a fragment of the right intermaxillary bone, with the roots of two large leeto. 

 and a row of small, uncompressed, conical teeth at the outer margiu ; and a 

 fragment of a palatal bone, with one large conical tooth having trenchant borders. 

 and the roots of two other teeth. 



Locality. Discovered in the Green Sand near Mount Holly, New Jersey. The 

 teeth of this species are relatively narrower compared with their length, than in 

 Enchodus Favjasii, Ag., from the Mtestricht beds. 



11. Xiphias astiquus. Based upon a specimen consisting of ten and a half 

 inches of the extremity of the prolonged maxillary bones. 



The posterior broken extremity of the specimen is transversely oval in section, 

 and measures 2 inches in its long diameter and 1 inch in it3 short diameter. 

 Anteriorly the specimen becomes more cylindrical, and at the anterior broken 

 end it measures 5 lines in diameter. 



Locality. Discovered by Dr. Chas. H. Buc'd, in the Green Sand of Burlingto.i 

 Co., New Jersey. 



12. Diodon vetus. Based upon numerous specimens consisting of water- 

 rolled jaws with the alveolar and oral teeth. 



The internal or oral teeth consist of a conjoined pair of piles, of from 6 to 10 

 trilateral laminae, measuring from 3}- to 4J lines wide. The outer or alveolar 

 teeth are composed of small lamellar denticles, of which the margin of 4 or 5 

 may be counted anteriorly in the space of a line. 



Locality. Discovered by Capt. Bowman, U. S. A , in the sands of Ashley river,
