over the body whorl in curved raLsed lines : third, the peripher}^ 

 sometimes carrying a couple of coarse lines followed below by 

 from four to six raised lines, also raised longitudinal ribs from 

 the peripher)^ to suture. Body whorl with raised revolving lines 

 extending to the end of the canal, carrying a few alternating 

 ones below the periphery ; aperture smooth within ; canal slightly 

 rostrate.

Re^narks. — This species seems to differ in some respects from 

 any heretofore described, but it may be only a variety of some 

 existing species like Turris denticula Bast. et. al. The fact is 

 that the Woods Bluff beds at Cave Branch contain so many numer- 

 ous varieties that it is almost impossible to locate them properly. 

 The w^hole subject of species in this family needs careful stud}^ 

 The young are often obtuse, and differ in shape and ornamenta- 

 tion from the adult so that they could be called new species, and 

 pass muster while a series would connect them all together. Am 

 not prepared to go into details but hope this subject will be 

 looked into by some of our younger students. Some specimens 

 may be hj'-brids, and are altogether perplexing. One ought to 

 have authentic specimens of the described species to even begin 

 the examination. All the species of this group from this localit}^ 

 seem somewhat stunted. 



Turris specus, n. sp., PI. i. Figs. 4, 5. 



Shell small, whorls probably seven (the embr3^onic tip is de- 

 fective) first three embryonic, then four spiral whorls ornamented 

 with a strong subsutural collar, then a slightly concave revolving 

 fasciolar space covering about one fourth of the whorl, followed 

 by a coarse cancellated surface ; the ribs cut b}^ about four im- 

 pressed revolving lines making a series of nodes, body whorl with 

 the same ornamentation above followed by coarse revolving lines 

 growing finer to the base ; outer lip smooth inside, columella 

 thickened, base somewhat rostrate.
