of the posterior suture, expanding again away from the suture, 

 slightly patulous anteriorly. Columella quite strongly concave 

 at the base of the body. Inner lip reflexed and fused with the 

 heavy parietal wash. 



Dimensions. — Altitude, 16.0+ mm. Maximum diameter, 4.2mm. 



Type Localittj. — Magnolia, Duplin County, North Carolina. 

 Duplin Formation. 



Observations. — Melanella hartschi has been confused in the refer- 

 ence collections with Melanella conoidea Kurtz and Stimpson. 

 It is, however, double the size of M. conoidea, and has a relatively 

 higher and more compressed body and fewer volutions in pro- 

 portion to the altitude. The variation in relative dimensions is 

 quite wide. The young are perfect little cones, — the sides of 

 the spire sloping uniformly to the sharply angulated periphery 

 of the body. 



We have the pleasure of naming the species in honor of Dr. 

 Paul Bartsch, of the U. S. National Museum, who has so critically 

 monographed the Melanellida^ of the West Coast. 



Distribution. — Duplin Formation. Magnolia and the Natural 

 Well, 1| miles north of Magnolia, Duplin County, North Carolina. 

 Muldrow's Place, 5 miles southeast of Mayesville, Sumter County, 

 South Carolina. 



Melanella bartschi is quite common in the Duplin of the Caro- 

 linas. 



Collections. — U. S. National Museum. Johns Hopkins Uni- 

 versity. Academy of Natural Sciences of Philadelphia. 



Melanella magnoliana new species. Plate II, flg. 8. 



General Characters. — Shell imperforate, straight, of moderate 

 size and moderately stout for the genus. Elongate conic in out- 

 line. Spire subulate, the body a little more than one-third the 

 total altitude. Whorls closely appressed, flattened, regularly 

 increasing in size, 12 in number, including the protoconchal turns. 

 Body whorl broadly rounded. Sutures distinct, even faintly 

 impressed toward the apex. 



Protoconch. — Nuclear turns minute, not more than 2 in number, 

 differentiated only by their very slight convexity. 



Sculpture. — External surface highly polished, entirely devoid of 

 sculpture. 



Aperture. — Aperture holostomous, rather narrow, obliquely sub- 

 ovate in outline, acutely angulated posteriorly. Outer lip feebly
