SCUTELLINA. 129 



This species of which three specimens lie before me, is elliptical, 

 thin, yellowish. The example of which measurements are given 

 above is very high in the back, the sides rather steeply sloping ; the 

 others, although of the same size (length 8, breadth 5-5 mill.), are 

 less convex, only 3 mill, high, and more regular. The blunt curved 

 apex is over the posterior margin in the more convex example, in the 

 others very near to it. The apex is not exactly in the middle later- 

 ally, but a little to the left of it ; the shell consequently is inequilateral. 

 The sculpture consists of fine, close radial riblets of unequal size, 

 and similar transverse cords, forming erect scales where they inter- 

 sect the radials. These last cords are short and irregularly placed, 

 running often over several radial ribs and their interstices, not form- 

 ing concentric lines, but merely interrupted wavy lines. The inner 

 margin is scarcely noticeably crenulated and is sloping all around.
