 1854. BiXNEY, Check List, No. 288. Bkot, List, p. 39. Reeve, Monog. Mela- 

 nia, sp. 2U1. 



Description. — Shell conical, smooth, rather thick, yellowish-brown; 

 spire short; whorls six, upper ones subconvex, with a brown rig.447. 

 band immediately above the suture ; body-whorl a little shoul- A 

 dered beneath the suture, and angulated in the middle, sur- ^^ 

 rounded by two narrow bauds, one above and the other ^c/ 

 below the angle ; sutures impressed ; aperture ovate, banded within ; 

 columella much curved, with hardly a perceptible sinus at base. 



Habitat. — Alabama. 



Diameter, -21 (5 millim.) ; length, '45 of au inch (11 millim.). 

 Length of aperture, -20 (5 millim.); breadth of aperture, -12 of an 

 inch (3 millim.). 



Observations. — A small, not inelegant species, which maybe com- 

 pared with M. ovoidea, Lea, and M. depygis, Say, as its nearest con- 

 geners. The former species I have never seen, but judging from the 

 description this differs from it in many particulars ; its form is pro- 

 portionately broader, the bands are more distinct; the body-whorl 

 has a distinct angle, which is also apparent on the penultimate whorl, 

 amounting there to a carination. The aperture also is much smaller. 

 The same particulars apply with equal force to Melania depygis, Say, 

 the two being so nearly alike in description that the M. ovoidea may 

 prove to be only a variety of Mr. Say's depygis. — Anthony. 



Except in the strise not being present, the shell resembles 

 G. rhombica^ Anth. All the specimens before me are labelled 

 "Kentucky" by Mr. Anthony.
