Hirudinea, part v., leech-metamerism. — E. J. Goddard : 



Contribution to a Itnowledge of Australian Hirudinea, 

 part vi., tlie distribution of Hirudinea, with special refer- 

 ence to Australian forms, and remarlcs on their affinities, 

 together with reflections on zoogeography. — H. J. Carter : 

 Revision of the genera Sympetes and Helseus, with descrip- 

 tions of new species of Tenebrionidae. 

 Calcutta. 

 Asiatic Society of Bengal, May 4. —A. C. Sen: "The 

 fight for the cows " in the Rigveda. The prevailing 

 opinion is that " the fight for the cows by the Angirases," 

 mentioned in the Rigveda, is a highly anthropomorphosed 

 •description of the monsoon storm in the Panjab. The 

 author of the paper has tried to prove that the story refers 

 to an actual fight for cows between two people, the Indo- 

 Aryans, commanded by their king Trita, and a non- 

 Aryan people called the Tanis, under the leadership of 

 their chief Vaia. — Rev. H. Hosten : Who planned the 

 Tdj? The subject has come up for discussion several 

 times of late years. Mr. Havell, in particular, is of opinion 

 that the Italian or French origin of the Tij cannot be 

 held. The present paper advocates a return to the tradi- 

 tional view, and offers the contemporary evidence of Friar 

 Sebastian Manrigue (1670) to show ' that Shdh Jahdn 

 approved of the plans of Jerome Verones, a Venetian 

 architect.^ Mr. H. G. Keene in his " Turks in India " 

 and his " Handbook of Agra " had come to the same con- 

 clusion from a study of Manrigue. His conclusion has 

 "been set aside. A full translation of Manrigue's Spanish 

 account is now presented, and it is hoped that the evidence 

 will be found satisfactory.
