ROSTELLARIA? COLLINA. 



Plate XIII, Figure 4, a, b. 



EUii^tical ; volutions, 6 ; tliose of the spire rounded ; body volution, with a rather wide, slight, 

 revolving depression near the suture. — (A cast.) 



BUCCINOPSIS. 



BUCCINOPSIS PARRYI. 

 Plate XIII, Figure 4, a, b. 



Sub-pyriform ; longitudinally undulated and ornamented with rugose revolving lines ; volutions 

 flattened above ; spire scalariform ; aperture large and patulous. 



Under this name I have described a cast which cannot be referred with accuracy to any known 

 genus. The beak is broken and was probably produced, 



Locality. — Same as preceding. 



TUREITELLA, Lam. 

 TURRITELLA PLANILATERIS. 



Plate XIV, Figure 1, a, b. 



Subulate ; volutions with two large beaded revolving lines, and two smaller ones beneath, 

 with an intermediate fine crenulated line ; sides straight ; the upper large revolving line gives 

 the shell a carinated character. 



Very distinct from T. seriatum-granulatum, Eoemer. The shell and sculpture are in perfect 

 preservation. It is accompanied by Lima Leonensis, a small Natica, and a small Astarte, which 

 has about five broad concentric prominent ribs, and triangular in form. It may be named Astarte 

 crassilira. 



ROSTELLITES, Conrad. 



ROSTELLITES TEXANA. 



Plate XIV, Figure 2, a, b. 

 Bostellites Texana, Con. Proc. Acad. Nat. Sci. Vol. VII, p. 268. 

 Narrow, elongated, with a subulate spire ; plaits of columella oblique, straight, narrow, acute, 

 largest above, and becoming obsolete towards the base ; volutions of the spire flattened on the 

 sides. 



The above genus is probably related to Pterocera. The specimens are very imperfect, only 

 one of them retaining any portion of the shell, and this is the columella with the plaits. 

 Locality. — Eagle Pass. 



NERINEA, Defranc. 



NERINEA SCHOTTII. 



Plate XIV, Figure 3, a, h. 



Elongated ; volutions concave or sub-angulated below the middle ; destitute of lines except 

 one slightly impressed line near and below the suture ; body volution angulated in the middle.
