the longitudinal lines forming tubercles at intersections ; tubercles sharp, 

 transverse, strongly developed on the periphery of the body whorl and 

 next one above, generally three large ones on the body whorl between the 

 varices; transverse striae numerous, composed of coarse lines, having 

 three finer ones between, and others between these ; line of growth fine ; 

 varices strong, pitted on the back side ; suture impressed, slightly 

 shouldered ; aperture ovate ; outer lip with a strong varix, nine tubercles 

 within, canal nearly as long as the aperture. 



Locality. Lower bed, Woods' Bluff, Ala. 



Young shells show more tubercles between the varices than the type. 

 Named in honor of the late Prof. Michael Tuomey. 



Fusus PEARLENSIS, Aldr. PL 1, fig. 17 a, 17 b. 



Fusus Pearlensis, Aldr. J. C. S. N. H., July, 1885. 

 Fusus Boettgeri, Meyer. Am. Jour, of Science, June, 1885. (Name 

 preoccupied.) 



This species has been found to be quite variable. 



Fusus MEYERI, Aldr., n. sp. PI. 3, fig. 12. 



Shell elongate fusiform ; spire slender, acute ; whorls fourteen ; surface 

 of the spire and body whorl with seven longitudinal broadly rounded 

 folds, which are spirally arranged, crossed by raised rounded striae, gen- 

 erally seven in number, rather distant, the central one making a sharp 

 carina on the center of each whorl, with erect longitudinal tubercules at 

 the intersections ; spaces between striae showing only lines of growth ; 

 canal very long, spirally striated with alternate raised lines; lines of 

 growth very numerous and almost obsolete ; mouth small, oblong-ovate ; 

 outer lip incurved, smooth. 



Locality. Lower bed, Woods' Bluff, Ala.; Matthews' Landing, Ala. 



The figured type retains four embryonic whorls ; three are smooth, the 

 fourth longitudinally striate. The Matthews' Landing form is smaller 

 and even more beautiful. One specimen has the ribs obsolete on the 

 upper half of the whorls and the periphery armed with erect longitudinal 

 spines, giving the shell a very strongly carinate form. Fusus Mississip- 

 piensis, Con., from Vicksburg, resembles this form, but this is more 

 carinate, with longer canal and spire ; the latter species has many more 

 revolving lines, and the outer lip is striate internally. Named in honor 

 of Dr. Otto Meyer.
