fig. 8 represents Cana/laria ellapsa, a Cretaceous, Texan, species 

 with no coluniellar plications. It is doubtless the same as Tri-

C. tortiplica shows at Woods bluff great variations, both as 

 regards form and general outline. As a rule the body whorl is 

 larger in proportion to the whole .shell than the figure would 

 lead one to suppose. This is particularly true of the Texan 

 specimens. The two anterior plicae are apt to be more or less 

 iniited at base, or in other words are both superimposed on a 

 common fold. 



Localities. — Alabama: Woods bluff ; Choclaw corner. 



Type. — From Texas, according to Conrad; Museum Acad. 

 Nat'. Sci., Phila. 



Cancellaria lanceolata, PI. 3, fig. S. 



Syn. C. la>u'L'ohita X\i\., Nautilus, vol. ii, p. 27, (fig.), 1897. 



"Shell elongated, whorls seven, first three nuclear and smooth, 

 the others cancellated and having three strong revolving Hues, 

 the middle one much the larger, the costae numerous and fine. 

 Whorls are shouldered, suture deeply marked; body whorl with 

 seven or eight revolving raised lines. Aperture oblong, outer lip 

 serrated by the raised lines, nearly smooth within. Columella lip 

 without callus, bearing two or more folds, part of the rai.sed lines 

 passing into the aperture to form them; canal .short, oblique, 

 slighth' twisted; no umbilicus. Length 'j % mm., diam. 3-^4 mm. 



''Locality. — Ala.: Chodlaw corner , Woods bluff horizon. 



"This little .shell has .some resemblance to C. pulcherrinia H. C. 

 Lea, but Mr. C. W. John.son, of the Wagner Free Listitute of 

 Science, has compared the two and finds the above distincfl. The 

 .specimens are not fully matured. One of the two .specimens has 

 been presented to the 'Lea Colle(5lion,' in the Academy of Natu- 

 ral Sciences of Philadelphia." 



This is evidently a young specimen of the same species shown 

 by pi. 3, fig. 8. It might now be characlerized as follows: — 

 Whorls about ic: 1-3 .smooth: remaining whorls with two stron •; 

 carinal rai.sed bandsor ridges and .sometimes a third ju^t above th • 

 suture; sharply defined raised axial lines extend from the snlur- 

 backward ol)liqueh' and outward to the u])])er carina, p:iss ove '
