116 LAND AND FRESH-WATER SHELLS OF N. A. [PART IV. 



Observations. — A single specimen only of this species was received 



by Major LeConte. There are no strong characters to separate it, 



but it is certainly different from any with which I am ac-

quaiuted. Like the canaliculata, Say, it is auger-shaped on 



the right lip, but it is a much smaller shell, and without the 



sulcatious of that species. There is an angle on the middle 



of the whorl which causes the sutures to be rather wide and 



max'ked. The apex being eroded, the number of whorls 



cannot be ascertained — probably eight. The aperture is 



about one-third the length of the shell. — Lea. 



The following, described at the same time as the above, is an 

 undoubted synonj-me, 



3Ielania spurca. — Shell smooth, pyramidal, somewhat thick, dark 

 brown; spire somewhat elevated ; sutures slightly impressed ; whorls 

 eight, flattened; aperture small, rhomboidal, angular at the rig. 220. 

 base, withiu white. 



Habitat. — Alabama. 



Diameter, •43; length, -98 of an inch. 



Observations. — This species, of which only a single one 

 was received by Major LeConte, has no striking character, 

 but cannot be placed with any other with which I am 

 acquainted. It is very regular in its form, with a patulous, 

 auger-shaped outer lip, the margin of which is quite sinuous. The 

 aperture is nearly one-third the length of the shell. It more nearly 

 resembles 31. regularis (nobis), than any other species, but is not so 

 large or solid a shell. — Lea. 



Mr. Reeve's figure does not represent this species at all. 

 I give a copy of Mr. Lea's figure. 



1 also place in the synonymy of this species 



Melania modesta. — Shell smooth, conical, somewhat fusiform, rather 

 thin, black, spire rather elevated; sutures linear; whorls flattened, 

 the last angular in the middle ; apertui'e elliptical, rather large, within 

 dark. 



Habitat. — Chattahoochee River at Columbus, Georgia. 



Diameter, -28 ; length, -67 of an inch. 



Observations. — A single specimen of this species came from Dr. 

 Boykin, with some others which I published some years since. This 

 one was deferred in the hopes of getting more for comparison. lu
