through the bluish-white shell. The suture is very inconspicuous, 

 indeed difficult to see, not distinct as the line figure shows. There 

 is a wide border below the suture, bounded by a white line, on the 

 last two whorls. The aperture is very narrow and long, the inner 

 lip nearly straight, calloused. The outer lip curves forward somewhat 

 in the middle. 



Length 5.75, diam. 2 mm. 



Length 5.6, diam. 1.8 mm.; about 7 whorls. 



This species is related to *S. metcalfei. It also has some resemblance 

 to Melania distorta Philippi, Eulima curva Jeffr., and E. incurva

Ren., of the Mediterranean. In these the mouth is somewhat 

 narrower than in Melanella, and a single series of linear varices runs 

 up the right side and curves towards the dorsal side as usual; but 

 they do not have the other characters of Subularia. 



On account of the prior use of the name distorta for species belonging 

 to Eulima {Melanella), Tryon renamed this species E. peasei; but 

 if we consider Suhidaria a group of generic rank there is no conflict 

 of names.
