Fig. 335 is G. inosculata, the immature shell of this species. The figure 

 of pallescens, which is a copy of Mr. Lea's, does not well represent the 

 species.

 Dark corneous, without bands. Rome, Geo. 



179b. G. circumlineata, Tryon. Figs. 237, 238. Fusi- 

 form, inflated, thick ; spire elevated, apex acute; whorls 6 — -7,

180. G. parva, Lea. Fig. 239. Conical, smooth, thin;
