26 STOMATELLA. 



spots or zigzag lines ; sculptured by numerous close microscopic spiral 

 stria?, several smaller alternating with larger ones, and somewhat 

 decussated by impressed growth lines. The spire is very short with 

 minute whitish nucleus; whorls 3?, convex, the last very large. 

 Aperture ovate, angled above, polished, and bright inside, and of a 

 blue color. Columella arched ; a slight chink is at the place of the 

 umbilicus. 



Alt. 7?, breadth 5} ; aperture, length 5?, breadth 5 mill. Meas- 

 ured as directed for Gena on p. 37.)

The color is very dark (" nigrescente plumbea ") in this species, 

 sparcely dotted with white ; but the dots are as often replaced by 

 spots, or V-shaped markings. On these the lip is edged with a row 

 of white dots. Color-varieties in the collection before me are figured 

 on pi. 2, figs. 35-37. It is this variability that causes me to consider 

 Mr. Brazier's S. ornata a variety of stellata. Its sculpture is the 

 same as the type — fine spirals with several still finer ones inter- 

 posed, decussated by growth-stria? ; color, " undulated brown, white 

 and pink flames, sometimes in the form of lengthened spots." Local- 

 ity, Barnard Is., X. E. Australia. 



From the Viti Islands I have a smoother form, with the minuter 

 spiral stria? obsolete. The color is sepia or umber-brown or pink, 

 with numerous spots and V-shaped marks of white. It may be called 

 variety ornatixsima. (pi. 2, figs. 35-37.) 



S. crassa Montrouzier. PI. 55, figs. 22, 23. 



Shell ovate-oblong, thick, back convex, with radiating, impressed 

 stria? of growth decussated by spiral subelevated strine ; dull ashen- 

 blackish, scarcely shining ; spire lateral, prominent ; whorls 4, con- 

 vex, separated by impressed sutures, the last one forming the greater 

 part of the shell. Aperture ample, rounded-ovate, bluish-white and 

 shining inside ; right margin acute, left subarcuate, appressed at the 

 columella and united with the right lip. Length 10 £, width 6 mill. ; 

 alt. 4J mill. ; aperture 7 mill, long, 5 broad. Measurements of an- 

 other specimen, length 8 \, breadth 5, alt. 4 mill.; aperture 6 by 4 

 mill. (Montr. & Souv.)
