 sinus narrow and deep ; outer lip plain, nearly straight, inner lip with five or six

 arranged as to leave between them a series of minute punctations ; suture very dis- 

 tinct ; a short distance below the suture there is a prominent revolving rib or carina 

 of twice the size of the other ribs. 



Dimensions. — Length "35 in., length of mouth "23 in., width of body whorl "14 in.

FASCIOLARIA, Lam. 



~ J F. Moorei. PL 67, fig. 27. Fusiform; whorls eight, spire acuminate; mouth 

 half the length of the shell, outer lip crenate within, inner lip with one tooth at the 

 upper part, columella nearly straight, with three or four nearly transverse folds, the 

 anterior of which is somewhat tuberculous ; surface marked by large nodes, seven on 

 the body whorl, crossed by numerous, alternating, revolving lines ; suture well marked 

 but shallow. 



Dimensions. — Length 1*5 in., length of mouth - 75 in., width of body whorl "65 in. 



This may possibly be identical with F. plicata, Lea, but it differs from his figure in 

 being higher, more slender and in having a straighter canal. 



This species appears to be common both at Wheelock and in Caldwell Co., Texas, 

 but the specimens in my collection from the latter locality are of a larger average 

 size than those from Wheelock, some of them being twice as large as any I have seen 

 from the other locality. 



^^ F. polita. PI. 67, fig. 28. Fusiform, whorls ten, rounded, spire elevated; aper- 

 ture narrow, columella short, straight, outer lip simple, crenate within, columella with 

 three large folds and one small one, the latter the most anterior ; surface smooth, 

 with several oblique impressed lines on the lower part of the body whorl. 



Dimensions. — Length *6 in., length of mouth *27 in., width of body whorl "18 in. 



Resembles F. elevata, Lea, but has a longer canal and differs in the width of the 

 mouth, the size of the folds and in the absence of all traces of teeth inside the outer 

 lip. 



Locality.— Caldwell Co., Texas. My collection. 



CYMBIOLA, Swains. 



C. Texana. PI. 67, fig. 33. Fusiform, whorls five, rounded and somewhat truncated 

 at the upper parts, suture very distinct, apex mamillated ; mouth? (very much broken, 

 in the only specimen I have seen;) columella straight, inner lip above faintly striate,
