2. Stomatella haliotoidea Sowerby.

Stat. 81. Pulu Sebangkatan, Borneo-bank. Reef, i Spec. 

 Stat. 176. Lilintah, South coast of Misool. Shore. I Spec. 



The two specimens differ in colour of the shell, that from Stat. 176 being marked with 

 dark brown flames on a yellowish-ground, the other is of a lighter hue, with a few white spots. 



3. Stomatella exquisita Sowerby. 



Sowerby. Journ. of Malacology, Vol. X, 1903, p. ^6, PL 5, fig 4. 



Stat. 299. Buka- or Cyrus-bay, south coast of Rotti- island. Up to 36 M. Mud, coral and 

 Lithothamnion. i Spec. 



The only specimen of this beautiful species is still young, its diameter being scarcely 

 5^0 Mill.; it is however interesting, as Sowerby did not know the locahty of his specimen. 

 In this and in the preceding species the posterior part of the foot is wanting. 



Stomatia Helbling.

The specimen is very elongated and strongly scalar, more than in any of the cited figures.

 Stat. 109. Pulu Tongkil, Sulu-Archipelago. 13 M. Lithothamnion-bottom. i Spec. 



The shells seem to be variable in colour; Adams calls it "reddish-brown". Reeve "brown", 

 PiLSBRY "rather brown"; the two specimens from Stat. 93 may perhaps be called reddish-brown, 

 though I should rather say brownish-red. The shell from Stat. 109 is variegated with large 

 white streaks, the sculpture however agrees with that of the more typical specimens. As one 

 of the specimens from Stat. 93 contains the soft parts, the lighter hue cannot be ascribed to 

 bleaching of the shells after death.
