FRESH WATER AND LAND SHELLS. 53 
Hab. Coosa river, Alabama, Prof. Brumby. Huntsville, Tenn., Mr. J. Clark. Tennessee, 
Prof. Troost. 
My cabinet and cabinets of Prof. Brumby and Mr. Clarke. 
Diam. .28, Length .83, of an inch. 
Remarks——Among the numerous Melanizx sent to me long since by my late friend Prof. 
Troost, were several specimens of the young of this species. I could not satisfactorily 
place them in any known species, and I put them temporarily with striatuia, (Nobis,) 
which is strongly allied to the species which I have described above. Recently, I have 
received from Prof. Brumby and from Mr. J. Clark several adult specimens, which leave the 
younger in my possession no longer in doubt,—they were recognised at once to belong to 
those more recently received. All the specimens—some dozen—before me are reddish; 
the striatula is horn-coloured, with a white aperture. ‘The latter is also flatter in the 
whorls, and not so carinate above, nor are the sutures so deeply impressed. Some of the 
specimens are quite smooth on the body whorl. Aperture about one-third the length of 
the shell. 
Me ania scutptiuis. Pl. XXX. Fig. 3. 
Testa perstriatd, conoided, subtenui, corned; spird acuminata, ad apicem carinatd et granulata; suturis 
irregulariter impressis ; anfractibus decim, subplanulatis; striis crebris et inter sculpturatd ; apertura parva, 
elliptica, ad basim angulata, intus albida; columella incurva tortdque. 
Shell thickly striate, conical, rather thin, horn colour; spire pointed, towards the apex carinate and granulate ; 
sutures irregularly impressed; whorls ten, rather flattened; strie close, and between them sculptured; aperture 
small, elliptical, angular at base, white within; columella incurved and twisted. 
Hab. Tennessee, Mr. J. Clark. 
My cabinet and cabinet of Mr. Clark. 
Diam. .24, Length .55, of an inch. 
Remarks.—Two specimens are before me, which are precisely alike. It is a very 
remarkable species, having regular and close striz# over the whole of the lower whorls, 
between which striz there is a double row of minute indented marks, very close to each 
other, and only visible with a lens. I have seen no such marks on any other species. 
In outline it is closely allied to striatula, (Nobis,) but it is a smaller species, and has not 
the cancellation of that species. The aperture is rather more than one-third the length 
of the shell. The outer lip is broken. 
Meranta Crarxu. Pl. XXX. Fig. 4. 
Testa plicata, claviformis, subtenui, tenebroso-fuscd; spira elevatd, attenuata; suturis subimpressis; 
anfractibus planulatis ; apertura parva, subellipticd, ad basim angulatd, intus tenebrosa ; columella tortd. 
Shell folded, club-shaped, rather thin, dark-brown; spire elevated, drawn out; sutures somewhat impressed ; 
whorls flattened; aperture small, rather elliptical, at the base angular, within dark ; columella twisted.
