Genus CLAVILITHES. 

 Clavilithes regexus nov. sp. PI. 7. fig. 6. 



This species is too poorly represented in the collection of the Sur- 

 vey to admit of complete characterization specifically. It is compar- 

 able in size with G. penrosei Heilp., and resembles the latter in the 

 lower part of the whorls and in the long, smooth columella. Above, 

 however, it shows no traces of a shoulder, the whorls are slightly 

 flattened laterally, and are smooth and polished. 



Localities. — Near McBee School- house, Cherokee Co.; between 

 Orrell's and Evergreen Crossing, Elm Creek, Lee Co.; 2 miles west 

 of Crockett, Houston Co.; Berryman Place, Kimble Headright, 

 Cherokee Co. ; 3 miles north of Crockett, Houston Co. 



Geological horizon. — Lower Claiborne Eocene. 



Type. — Texas State Collection. 



Clavilitlies humerosus Conrad, var. texanus nov. var. PI. 7, fig. 7. 



Differs from typical humerosus in having the sides of the body 

 whorl nearly rectilinear, in having a more prominent shoulder at the 

 suture, and in being of a smaller size generally. Many specimens 

 approach closely Clavilithes longcevus of the middle Eocene of Europe. 



Localities. — Near McBee school-house, Cherokee Co. ; Alum Creek 

 Bluff, Colorado River, Bastrop Co.; Wilson Reid Headright, Brazos 

 Co.; Hurricane Bayou, Hodge's Headright, Houston Co.; north- 

 west corner of Madison County ; Collier's Ferry, Burleson Co. ; 

 Collard farm, Sparks' Headright, Brazos Co., Tex. Also in Clai- 

 borne and Bienville Parishes, La., and 2? miles east of Newton, near 

 Enterprise, Miss. 



Geological horizon. — Lower Claiborne Eocene. 



Type. — Texas State Museum. 



Clavilithes kennedyanus nov. sp. PI, 7, fig. 8. 



Specific characterization. — General form as figured; whorls 10 or 

 12; 1 and 2 probably smooth; 3-10 with nodular ribs most promi- 

 nent on the lower portions of the whorls, crossed by raised spiral 

 lines and by even lines of growth ; body whorl in the type specimen 

 very poorly preserved, but showing few signs of costse; columella 

 ponderous. 



Locality. — Smith ville, Bastrop Co., Tex. 



Geological horizon. — Lower Claiborne Eocene. 



Type. — Texas State Museum.
