THE MOLLUSCA OF TOEEES STEAITS. 165 



112. Teivia oetza, Lam. 

 Station 13, Murray Island. 



113. Teivia staphyl^a, L. 

 Station 13, Murray Island. 



Steombid^. 



114. Steombus (Gallinula) Campbelli, Gray. 



Station 10, Ctiannel between Hammond Island and Wednesday 

 Spit. 



115. Steombus (Gallinitla) cakaeiitm, L. 

 Station 13, Murray Island. 



116. Steombus (Gtallikula) Isabella, Lam. 



In our opinion a mere variety of S. canarium, L., but some 

 authors place specific reliance on the thinner substance aad 

 absence of freckled marking. The distribution of the two species 

 is the same. 



Station 13, Murray Island. 



117. Steombus (Gtallinula) Sibbaldi, Soiv. 



Hitherto considered endemic in Ceylon, a remarkable extension 

 of range is now presented. 

 Station 2, Warrior Island. 



118. Steombus (Gtalliis'ula) ueceus, L. 

 Station 13, Murray Island. 



119. Steombus (Gtallinula) vaeiabilis, Sivains. 



120. Steombus (G-allinula) vittatus, L. 



Young, but finely coloured, being tesselated with brown. 

 There is also in the collection, from Mer, a very remarkable but 

 juvenile form, slightly variced, white, fusiform, and closely 

 striate throughout. 



Station 4, between Ormans Eeef and the Brothers Island ; 

 Station 13, Mer ; Station 5, Boydong Cays. 



121. Steombus (Cajstaeium) dentatus, L. 



Only, we think, a sub-species of *S'. urceus, L., but at all events 

 it is the prevailing form. 



Station 13, Mer (Murray Island). 



122. Steombus (Mojstodactylus) Lamaecki, Gray. 



123. Steombus (Monodacttlus) melanostomus. Swains.
