SCHIZOSTOMA. 371 



rather inflated ; fissure small, oblique ; aperture large, rhomboidal, 

 whitish within ; columella thickened above. 



Habitat. — Tuscaloosa, Alabama. 



Diameter, -47 ; length, -83 of an inch. 



Observations. — This is a robust shell, being thicker and heavier 

 than any other species of this genus which I have observed. The 

 aperture is nearly one-half the length of the shell. Two specimens 

 were sent together by Dr. Budd, presuming they were the rig. 700. 

 same. One, however, which is not quite a mature shell, 

 has little or no fissure. The other, from which the de- 

 scription is made, has a wide but short fissure, and the 

 margin of it opens obliquely. — Lea. 



The following is the description of 



ScJiizostoma funiculatum. — Shell striate, elliptical, rather thick, 

 chestnut-colored; spire obtuse; sutures much impressed; whorls 

 Fig. 701. convex ; fissure rather large, oblique ; aperture large, el- 

 liptical; columella thickened above. 

 Habitat.— Tuscaloosa, Alabama. 

 Diameter, -4; length, -66 of an inch. 

 Observations. — A single specimen only was obtained 

 by Dr. Budd of this species. It is short, stout, and 

 almost subrotund. It has two elevated, cord-like lines, revolving on 

 the whorls. One immediately under the suture, the other below that 

 again. The aperture is more than half the length of the shell. The 

 apex is so much eroded as to prevent the number of whorls being 

 ascertained. There are about six. — Lea. 



Having examined Mr. Lea's original specimens of the above 

 descriptions (both of which are figured) as well as other shells 

 of intermediate forms, I believe that the two should be united. 

 Mr. Reeve's figure 3 of this species is a Goniohasis Iceta, 

 Jay. Mr. Reeve's figure of funiculatum quoted above does 

 not so well represent that variety as his figure lb, which he 

 introduced to illustrate Mr. Lea's S. constrictum (considered 

 by Mr. Reeve to be a sj'nonj'me of pagoda). This species is 

 very closely allied to the long-fissured S. pumilum of Lea.
