STOMATELLA. 13 



Several specimens of this well-marked form are before me, procured 

 from various sources, and under various names, one of which is S. 

 lyrata Ad. I do not find any description of such a species by Adams, 

 and doubt its existence. Specimens of the species now before me 

 were received by Mr. Tryon from Arthur Adams under the name of 

 " S. elegans Gray." 



S. CUMINGII A. Adams. PI. 52, fig. 67. 



Shell auriform, imperforate ; spire depressed ; whitish, buff glisten- 

 ing, transversely spirally ribbed, the ribs elevated, subequal, 

 crenelated, articulated with reddish-brown, the interstices or- 

 namented with delicate longitudinal lamellae; aperture patulous, 

 sulcate within ; inner lip subreflexed. This is a large and elegant 

 species, with a peculiar yellowish glistening tinge in the intervals 

 between the spiral rugose ribs ; the aperture is very transverse, and 

 the inner lip is reflexed on the columella. (Ad.) 



Habitat unknown.
