272 NORTH-CAROLINA GEOLOGICAL SURVEY. 



FAMILY TURBINIDAE TEOCHUS PHILANTROPUS. (Fig. 167.) 



Shell conical, but rather depressed; 

 whirls slightly angular at base, and orna- 

 mented with spiral beaded lines, alternat- 

 ing in size. 



TROCHUS. (Fig. 168.) 

 It appears to differ from T. armillatus, 

 but I am unable to refer it to any of the 

 FIG. lesT species described in the miocene beds. 



DELPHINULA QTJADRICOSTATA. N. S. (Fig. 180.) 



Shell small, thin ; whirls, few, angulated and furnished with 

 four ribs, which are crossed by lines of growth ; aperture an- 

 gular. 



Found occupying the interior of the large univalve shells 

 of the miocene. 



\ 



ADEORJBIS. WOOD. (Fig. 181.) 



I have placed this figure under this genus, though it does 

 not agree with it in every particular. 



FAMILY TORNATELLIDAE. 



This family has a convoluted shell ; it is cylindrical, or sub- 

 cylindrical, with a long narrow aperture ; columella plaited. 



TORNATINA CYLINDRICA. N. 8. (Fig. 182.) 



FIG. 182. Shell small, convoluted, cylindrical, porcel- 



,. lanous, or polished ; spire depressed ; whirls, 



f 1 1 angulated ; suture channelled ; aperture long 



and narrow ; outer lip arcuate ; columella with 



one fold. 



This small shell resembles a cyprea, or some of the smaller 

 species of olivas. It is not uncommon in the miocene ; it is 

 usually found in the cavities of the larger univalves.
