CONTRIBUTION TO THE PALEONTOLOGY OF TRINIDAD. 71 



sharp with concave spaces ; no spiral sculpture shown ; suture distinct, not deeply 

 impressed ; body whorl long, terminating in a canal, which is missing in specimen 

 figured; aperture long and narrow, inner lip showing a few plications, but the 

 aperture is filled in so that the lips are almost completely hidden/ ' 



Type locality in or near McConnico's plantation, Wilcox County, Alabama. 

 Midway Eocene. 



Remarks. — In view of the columellar plaits on L. vrilcoxiana and on the 

 variety aldrichiana it seems doubtful whether the specimen from near Midway, 

 Alabama, mentioned by Professor Harris 46 is this species. As far as could be 

 determined, the columella of that shell was smooth. 



Lyria wilcoxiana Aldrich var. aldrichiana

Description. — The Soldado shell although a varietal form is apparently the 

 most perfect specimen of this species ever found. 



It shows distinctly six, short well marked plications on the columella. These 

 were obscured in Mr. Aldrich's type by the matrix. 



The Soldado form differs from Mr. Aldrich's description in not having a 

 distinctly marked suture, and especially in the fact that the plications extend 

 only over the dorsal half of the last whorl. This peculiar characteristic is well 

 illustrated by the figure. 



The writer takes pleasure in naming this variety for Mr. T. H. Aldrich, of 

 Birmingham, Alabama, by whom the species was described. 



Height 23, greatest diameter 14 mm. 



Locality.— Bed No. 2, Soldado Rock, Gulf of Paria. 



Geological horizon. — Midway Eocene. Equivalent to the Midway of Alal >ama 

 and of the Rio Maria Farinha beds in Brazil.

Heilprin' s original description. — "Ventricose; whorls about nine, the body 

 whorl nodulated on the most convex portion (nearly central), the nodulations 

 consisting of a single series of sharp, obtusely pointed, and flattened spines or 

 nodes which frequently appear double by the crossing of an impressed line over 

 their basal portion; upper volutions with a similar series of nodes almost im- 

 mediately above the sutural line, and gradually dividing off into a crenulation, 

 upper surface of the whorls concave, faintly striated, the sinual rugae indicating 

 but a faint sinus; lower surface with numerous well developed revolving lines, 

 which show a tendency to alternate. Aperture exceeding the spire in length, 

 considerably contracted at about its center.
