Specimen figured. — Aldricli's specimen from Chodlaw corner. 



Cerithiopsis conica, I'l. 9. fig- >">■ 



Syn. C. conica Aid., Bull. Am. Pal., vol. 2, p. 178, pi. 2, fig. 4, 1897. 



For Aldricli's description, see above reference. 



The specimens in hand, from Woods bluff, agree very well 

 with Aldrich's description and figure, except his specimen was 

 much smaller than this, and no mention is made of the raised 

 lines or plaits on the columella. The largest whorl of our speci- 

 men has a somewhat finer costation than the upper whorls have; 

 the costae are more arcuate and thread-like.
