The shell is over twice as long as broad in Teinotis, and the foot 

 is correspondingly elongated. It projects more posteriorly than in 

 the rounder species of Haliotis. Like the others, this species has a 

 developed operculigerous lobe; with a deep longitudinal central 

 furrow.

Shell oblong or kidney-shaped, over twice as long as wide ; spire 

 subterminal ; surface nearly smooth ; open holes five to seven. 



This is an elongated species, convex ; either greenish or flesh- 

 colored, with triangular brown markings. The surface is almost 

 smooth, polished ; the spire has narrow spiral threads, 6 above, 2 

 below the row of holes ; these threads are separated, and composed 

 of tiny beads, brilliant colored, usually alternately orange, robin's- 

 egg blue and yellow or white; the surface between holes and colu- 

 mella is convex, and has five or six smooth spiral threads. The 

 spire is composed of 3 whorls ; it is rather elevated. Inside silvery, 

 beautifully iridescent; columellar plate wide, sloping outward. 

 Holes oblong, their edges not raised. 



Length 80, width 37, convexity 12 mill.

A species like no other in form. There is considerable variation 

 in color. The spiral dotted threads of the spire are also unique.
