FASCIOLAEIA. 139 



also encircled by cycles of lineations, and the •whole are rendered 

 slightly uneven by the passage of the closely-set growth-lines ; 

 aperture ovate, but contracted and drawn out in front; outer 

 margin thin, striate, and Urate within; columellar border smooth, 

 with three conspicuous, drawn-out plaits, situated anteriorly ; canal 

 long and sinuous, especially in the adult. 



One specimen in the Museum collection is larger than the type 

 as measured by Professor Tate ; its dimensions are given below. 

 This species is of the same general character as the living 

 F. papulosa, Sowerby, which Tryon' says is the young of 

 F. gigantea, Kieuer ; the former name, however, has priority. 

 The spire of the fossil is relatively shorter, the whorls are more 

 serrate, and the anterior canal is longer. 



Dimensions. — Length 73 mm.; breadth 31mm.; length of 

 aperture 20 mm. ; length of canal 24 mm. 



Form, and Loe. — Eocene : Victoria.

This species differs from F. cristata in having a less elevated 

 spire, a shorter anterior canal, and in being less spinose, though 

 the general character of the ornament is somewhat similar. The 

 protoconch is composed of two smooth globose turns, the front 

 portion being striate and obscurely costate ; its junction with the 

 ehell in the brephic stage is very abrupt. The columella carries 

 three plaits, the largest being situated anteriorly, and bordering 

 a sharp twist leading to the curved canal.
