If the above mentioned characters are sufficient to 

 separate it from the H. funatus^ I propose the name of 



Hamites Haanii. 



I found it in a stratum of a granular spathose limestone 

 which lies below the shale near the Harpeth river, in 

 Davidson county, where this stone is quarried for tomb- 

 stones, &c. I do not know whether the Hamites have 

 been found in any strata below the chalk. Those men- 

 tioned by Brongniart, in the above mentioned work (see 

 pages 83, 95, 96 and 99), were found in craie tufau 

 et de la glauconie of Rouen, of La Perte du Rhone, near 

 Bellegarde, and in the mountains of Fis and Sales, in the 

 Alps of Savoy. According to Mantell, Buckland, Phillips, 

 Desnoyers, Sowerby, Hoenighaus, Risso, and Defranc, 

 it occurs in similar strata, chalk and green sand, conse- 

 quently in the upper secondary strata. Defranc mentions 

 of the 15 species, only one as doubtful whether it occurs 

 anterior to the chalk ; De la Beche places 20 species in 

 the list of organic remains of the cretaceous group, and not 

 a single one in the lists which he gives of inferior groups, 

 whereas it occurs here below the coal strata, and is asso- 

 ciated with Turbinolia mitrata, Goldfuss, which, accord- 

 ing to Schlotheim, occurs in the upper transition. 



Turbinolia mitrata, Goldfuss. 

 Goldfuss has subdivided the genus Turbinolia of La- 

 marck, and has formed of it his genus Cyathophyllum. 

 The characters laid down by Goldfuss for the Turbinolia 

 are: "a simple, free, turbinate, or inverted conical, 

 stellated, lamellar polyp cell, composed of vertical lamel- 

 lae joined together in the centre, forming on the upper 

 part a single terminating star, and projecting on the 

 side like small ribs. The sides of these lamellsB are 

 covered with warts. The latter character is not men- 

 tioned by Lamarck, and brings most of the fossils of our
