NEW MELANIDiE OF THE UNITED STATES. 249 



Remarks. — This is rather a robust species, and judging from the specimens before 

 me, I should presume that there would be much regularity in the species. On one 

 of the specimens there are two obscure hair-like bands, one on the middle of the body 

 whorl and another near the base. Other specimens have only a very obscure thin 

 band near the base. Very probably specimens may be found with a third band near 

 to the suture, and others with better defined bands'. Some were chestnut brown. 

 The upper whorls were rather flattened, and the lines of growth few and ob- 

 scure. The impression made by the lip-cut is well defined, and forms a strong, 

 narrow, hem-like line below the suture. The outer lip stands close to the body 

 whorl. The aperture is one half the length of the shell, and the base is obtusely 

 angular. This species, in general facies, is near to glandula, herein described, but 

 differs in the form of the lip-cut, which is narrow, deep and straight. It is also a 

 much larger species, and is without the well-marked shoulder of glandula. 



SCHIZOSTOMA GLANDULA. PI. 35, fig. 53. 



« 



Testfi loevi, curta, valde inflatix, subcrassa, luteo-cornea, exilissinie striata, imperforata ; spira obtusa ; suturis 

 valde iinpressis ; anfractibus senis, vittatis, ultimo inagno et tumido ; fissura obliqua, brevique ; apertura 

 subgrandi, elliptica, intus albida ; columella albida, superne inerassata ; labro acuto, subsinuato. 



Shell smooth, short, much inflated, rather thick, yellowish horn-color, minutely 

 striate, imperforate ; spire short ; sutures much impressed ; whorls six, banded, the last 

 large and swollen ; lip-cut oblique and short ; aperture rather large, elliptical, white 

 within ; columella whitish and thickened above ; outer lip sharp and somewhat 

 sinuous. 



Operculum ovate, brown, with the polar point very close to the inner lower edge.

My cabinet and cabinet of Dr. Showalter. 

 Diam. -36, Length -57 inch. 



Remarks. — A single specimen only was received from Dr. Showalter. The lip-cut 

 in this species is not deep, but it is wider than usual, and being oblique, pi^esents 

 more of the whorl within than usual. In the specimen before me there are two 

 small hair-like bands, one immediately under the shoulder and the other very near 

 to the base, and in the middle there is a slight indication of a band, but these indis- 

 tinct bands do not become visible in the interior except in a very small degree. The 

 shoulder is slightly impressed, giving the suture a hem. In color it is nearly the 

 same with glans, herein described, but it differs entirely in the lip-cut, and is a much 

 smaller species with a much lower spire. It is very likely that in other specimens 

 the color may be found to vary. The outer lip stands well off from the body whorl,
