Tectibranchs. The matter can only be decided when more perfect 

 material is at hand. 



Locality, Wood's Bluff, Ala. 



Cyprsea smithi Aid. PI. XXI, fig. 4. 



This is broader posteriorly than typical smithi, and has a less con- 

 spicuous posterior termination of the labium, yet it is most likely of 

 the same species. It seems to be the forerunner of C. dalli Aid. 



Locality, Wood's Bluff, Ala. 



Solarium huppertzi var. Har. PI. XXI, fig. 5. 



The markings on this specimen are somewhat finer than those of 

 typical huppertzi, but this may be only a varietal feature. Again, 

 huppertzi was described from a young, small specimen ; this is more 

 nearly full grown. 



Solarium sylvaerupis n. sp. 



Syn. S. texanum Dall, Tr. Wag. Free Inst. Sci., Vol. Ill, p. 326. 



After examining the type of texanum in the Academy's collection, 

 it was found to be the same as Conrad's scrobiculatian. Hence the 

 larger, beautiful form described by Dall under the name "Texauwn 

 Gabb " from Wood's Bluff, must have another name. 



Solariella sylvaerupis n. sp. PI. XXI, tig. 6, 



Specific characterization. — Size and general form as indicated by 

 the figures; whorls about 6, with about 5 strise on each; slightly 

 shouldered at the suture, bearing there a row of beads or tubercle;- ; 

 nacreous within; umbilicus crenate at the periphery, granularly 

 striate within. 



Locality, Wood's Bluff, Ala. 



LIGNITIC STAGE (lOWER). 

 Meretrix mortoniopsis var. Hp. Plate XXII, figs. 1 and 2. 



The figures represent two well-preserved specimens of this species 

 from the lower Lignitic. It seems well to have them accurately 

 figured, since their relationship to the species of this genus described 

 by Rogers and Conrad from Virginia is still in an unsettled state. 



Locality, Bell's Landing, Ala. 



Tellina lignitica n. sp. PI. XXII, fig. 3a. 



Specific characterization. — Size and general form as indicated by 

 the figures ; substance of shell very thin ; smooth ; 2 cardinal teeth 

 in each valve ; a furrow in the upper anterior margin of the left 

 valve causes the same to form two obscure teeth. 



Locality, Gregg's Landing, Ala.
