THREE PLATES TO ILLUSTRATE THE SCALPELLIDAE AND 
IBLIDAE OF INDIAN SEAS, WITH SYNONYMY 
| | AND NOTES. 
By N. ANNANDALE, D.Sc., F.A.S.B., Director, Zoological Survey of India. 
The three plates now published were prepared about five years ago, to be issued 
with an account of the Scalpellidae and Iblidae of Indian seas, which was to be 
arranged on the same lines as my account of the Lepadidae published in these 
 Memoirs.‘ As soon, however, as the Surgeon Naturalist on the ‘ Investigator’ began 
to dredge in shallow water off the coast of Burma,” it became clear that our know- 
ledge of these barnacles was still very incomplete so far as the eastern side of the 
Bay of Bengal was concerned, and it seemed best to defer the publication of the 
monograph until further material could be obtained. 
It had been arranged by the Government of India that the ‘ Investigator’ should 
be entirely devoted to zoological work for one month in every year, and that a con- 
siderably enhanced grant should be made to the Surgeon Naturalist for apparatus 
and books, but war broke out and the scheme has had to be postponed indefinitely. 
In these circumstances I think it best not to defer the publication of the three 
plates any longer, seeing that all the species figured in them have now been described 
and that in the case of two’ of these species no figures have hitherto been issued. 
The plates are numbered VI, VII and VIII because they are to be regarded as a 
_ continuation and final instalment of the ““ J//ustrations 0] the Zoology of the R.I.M.S. 
Investigator’’, in which five previous plates have already been devoted to the Cirri- 
pedia. These were published in two series in 1907 and 1908 respectively. 
A preliminary account of the Indian species of Scalpellum (s.l.) has already been 
issued in Vols. V and IX of the Records of the Indian Museum.* 
The figures have been drawn by Babu A. C. Chowdhary, S. C. Mondul and 
D. N. Bagchi, who have devoted their usual skill to their preparation.
