G6 Mr. H. Fulton on the X. — Description of a neio Species o/Tliaiiria {Moore) ^ a 6^ewMso/Araatliusiina3. By Philip Crowley, F.L.S. &c. Thauria intermedia^ sp. n. Male. — Upperside. Fore wing deep brown, slightly shot with purple, the base ferruginous brown, crossed by a broad oblique creamy-white band from the costa just beyond the cell to the outer margin below iirst median nervure ; two subapical spots, the upper creamy white, the lower less defined and tinged with blue. Hind wing deep brown, the base suffused with ferruginous brown ; the apex and the anal third from discoidal nervule to the anal angle rich orange-brown. Underside. Similar to T. pseudalaris^ the band of the fore wing being about double the width and the ocelli of the hind wing being much larger and more pronounced. Expanse 4*5 inches. Hob. Burma and Tenasserim. In collections Crowley, Adams, and Brit. Mus. This species has hitherto been confounded with T. pseud-alaris^ and is mentioned by Messrs. Elwes, De Niceville, Moore, and Distant as such. It is at once distinguished from the true pseudalaris, which occurs in Perak, Malacca, and Salanga, by the much greater breadth and paler colour of the band. XI. — A List of the Species of Amphidromus, Albers, toith Critical Notes and Descriptions of some hitherto undescribed Species and Varieties. By Hugh Fulton. [Plates V.-VII.] Having had opportunities of examining a large number of specimens, including most of the types, of this admittedly difficult genus, I have thought that a list of all the known species might be useful. I have endeavoured to arrange the species according to their affinities, and have given a figure of all the unfigured species. The genera or subgenera Pseudo^Mrtula and Beddomea are omitted from this list, tlie species of which have sometimes been included with Amphi-dromus^ but they appear to me to be, from their concho-logical characters, sufficiently distinct to stand apart.
