EURYC.ELON. 343 



Operculum ovate, spiral, dark brown, with the polar poiut near to 

 the base. 



Habitat.— Coosa. River, Alabama; E. R. Showalter, M.D. 



My cabinet and cabinet of Dr. Showalter. 



Diameter, '39; length, -78 of an inch. 



Observations. — This is a very remarkable and beautiful little spe- 

 cies. There are three specimens before me, all of them having four 

 somewhat distant, low, obtuse, rather large nodes. I have j.j„ g^j 

 never seen any other species with this kind of nodes. The 

 texture of the shell is delicate, the epidermis smooth and 

 shining. Two of the specimens have four well defined, 

 brown bands, which are strongly marked inside and out. 

 The third specimen is without bands, but it is covered with 

 very remarkable trausvei-se strias, which traverse the nodes as well 

 as the other parts of the surface. Tlie aperture is more than half the 

 length of the shell. — Lea. 



See remarks on next species {31. lacTiryma, Anthony) with 

 which it is identical. 



3a. E. lachryma, Anthony. 



Melania lachryma, Anthony, Reeve, Monog. Melania, sp. 473, May, 1861. Bhot, 

 List, p. 32. 



Description. — Shell conically ovate, thick, fulvous-olive, encircled 

 Fig. C53. Fig. C53a. with numerous black lines ; whorls five, slopingly 

 convex round the upper part, then gibbous, and 

 obtusely tubercled, longitudinally, plicately stri- 

 ated throughout; aperture narrowly ovate, rather 

 small, sinuately effused at the base. 

 Habitat. — United States. (Alabama — label attached to type, G. W. 

 Tryon, Jr.) 



Observations. — A prettily painted species of a rude, obtusely tu- 

 bercled form. — Jieeve. 



The figure is a cop}' of Mr. Anthonj-'s tj-pe. This shell and 

 gratiosa are identical, but I am unable to ascertain which has 

 priority. A very beautiful specimen in Mr. Lea's collection is 

 closely and sharply sculptured with transverse striae.
