For some years past the main biological work of the ' Investi- 

 gator ' has been carried out in comparatively shallow water, and 

 the Surgeon-Naturalists (Capts. R. B. Seymour Sewell and T. L. 

 Bomford) have devoted considerable attention to the littoral and 

 sub-littoral fauna. The result has been, so far as the Cirripedia 

 Pedunculata are concerned, to add several new and interesting 

 species to the fauna of the Bay of Bengal. I propose here to 

 describe or notice these, together with a species of which specimens 

 have been obtained by Mr. J. Hornell off the coast of Baluchistan. 



Family Scai,pei,LIDAE. 



Scalpellinae, PiLsbry, U.S. Nat. Mtis. Bull. 60, p. 4 (1907). 

 Pollicipedidae Annandale, Mem. Ind. Mus. II, p. 63 (igog). 



Of this family four species have now to be added to the 

 Indian fauna, one belonging to the genus Lithotrya and three to 

 the subgenus Smilium of the genus Scalpellum. 



Genus Scalpellum, I.each. 

 Subgenus Smilium Gray. 



Annandale, Rec. Ind, Mus. V, p. 145 (igio). 



The species of this subgenus often inhabit shallower water 

 than those of Scalpellum (s.s). It is, therefore, not surprising 

 that the exploration of the coast of Burma should have resulted 

 in the discovery of forms not hitherto known from these seas, for 

 most of the biological work of the ' Investigator ' has been carried 

 out hitherto in much deeper water. The three species here noted 

 have all been found already elsewhere in the Oriental Region.

This species was originally discovered by Dr. P. van Kampen 

 in 13-16 fathoms off the coast of Sumatra. It has since been 

 found off Singapore and in the Gulf of Siam (by Dr. Th. Mortensen)
