This, if trabeatus at all, is a strongly spinous variety that 

 lacks all traces of the third carina which generally characterizes 

 the genus; the specimen herewith figured is the same specimen 

 shown by fig. 6, pi. 4, of Bull. No. 2. It is from Matthews' 

 Landing and belongs to T. H. Aldrich. A fragment of the 

 same is in our collection from Dale's Branch. 



A specimen in Dr. SafTord's collection from Middleton, Harde- 

 man Co., Tenn., is very strongly bicarinate but the tubercles are 

 not so large nor so far apart. A small specimen is in our collec- 

 tion from bed e, ^ mi. N. of Ripley, showing a great number 

 of denticulations on the upper carina while the lower is smooth. 



Levifusus htibbardi n. sp., PI. 9, fig. 11. 



Specific characterizatio7i . — General form somewhat more slender 

 than shown in the figure owing to the compressed and broadened 

 condition of the cast from which the figure was drawn; whorls 

 about 7 or 8; spiral whorls marked by («) a prominent median 

 carina bearing a number of slightly flattened spines, (<5) a more 

 or less prominent spiral line midway between the carina and 

 the suture below; suture with a spiral line; body whorl strongly 

 bicarinate, each carina bearing about 20 slightly flattened spines 

 which affect the surface but little above or below their respective 

 carinas; somewhat below the lower strong carina there is a third, 

 consisting of a narrow, raised, strong line which likewise bears 

 about 20 small spines; still below this faint carina there is a strong 

 revolving line; outer lip angular at points where the carinas
