Adult specimens of what I take to be the true solariiformis are 

 before me, and one is figured on pi. 67, fig. 73. The shell is 

 elevated ; bluntly conic, whorls 6, the earlier two rounded, the rest 

 with a strong angle on the upper surface, the last with another at 

 the periphery. There are slight growth-lines but no spiral strise 

 above the periphery ; the base has a beaded carina bounding the 

 very deep umbilicus, and outside the carina about 7 smooth con- 

 centric liros becoming smaller toward the periphery. The umbilicus 

 is clathrate inside, funnel-shaped and has about 6 spiral lirje crossed 

 by numerous radiating riblets. The aperture is rounded-rectangular, 

 pearly and pinkish inside. Alt. 9, diam. 9 mill. The color is pur- 

 plish-brown, with numerous narrow, irregular or zigzag radiating 

 light streaks. The upper surfice of the earlier whorls is seen 

 to be slightly fluted under a lens, on the flat portion above the superior 

 carina. The iridescence of the pearl often shows through the outer 

 coat on the spire. There are often a few spiral raised threads in the 

 concave portion between the two carinse on the body-whorl. 



This is one of those forms which might be equally well placed in 

 true Solariella.
