of that city, where many plants were collected. Thence a journey was 

 made to the new settlement of Santa Cruz on the Paraguay, about half- 

 way between Villa Maria and Diamantino. The flora here is of a mixed 

 character, nearly 37 per cent, of the plants being common to tropical South 

 America, upwards of 27 per cent, occurring in the N. Brazil Guiana 

 Province of Eugler, with 205 per cent, common to that province and the 

 S. Brazilian, and only 13 per cent, of S. Brazilian types. From Santa 

 Cruz a party penetrated through the primeval forest lying to the north, and 

 reached the Serra de Sapirapuan. The forest flora is markedly Amazonian 

 in character, nearly 50 per cent, of the plants being natives of Amazonia or 

 of the neighbouring countries within the N. Brazil Guiana province or 

 related thereto, while the proportion of species common to tropical America 

 falls to rather more than 28 per cent., the South Brazilian element being 

 present only to the extent of 9*5 per cent. Returning to Santa Cruz, the 

 Rio Braciato was partly explored, and the Paraguay ascended to the neigh- 

 bourhood of Diamantino. The party then came down the Paraguay to the 

 Corumba, where many plants of interest were found. The expedition was 

 partly disbanded at Asuncion. Among the Amazonian plants found at 

 Santa Cruz or in the forest may be mentioned, Randia ruiziana, Bertiera 

 guianensis, the Loranthad, Oryctanthus rujicaulis, Catleya superba, Epi- 

 dendrum. imatophyllum, Hodriguezia secunda, &c. The collections comprise 

 close upon 700 species, of which rather more than 200 were considered 

 to be new, and there are eight new genera. The southward extension of 

 the Amazonian flora to a latitude well within the Paraguay river system 

 was regarded as a noteworthy feature. 



On behalf of Mr. G. M. Thomson, of Dunedin, N.Z., Mr. W. Percy 

 Sladen read a paper on a new freshwater Schizopod from Tasmania, 

 illustrating his remarks with graphic sketches on the black-board to indicate 

 its affinities and differences.

The Secretary read a report on the additions that had been made to 

 the Society's Menagerie during the months of June, July, August, and 

 September. Among these special attention was called to four South-Island 

 Robins, Mir a albifrons, from New Zealand, presented by Capt. Edgar J. 

 Evans; an adult male of Stairs' Monkey, Cercopithecus stairsi, presented 

 by Mr. F. Hintze on June 7th ; a family of six European Beavers, Castor 

 fiber, consisting of a male, a female, and four young ones, from the Lower 

 Rhone; a young Corean Sea Eagle, Haliaetus branickii, obtained from 

 Corea; a specimen of the Great Grebe of Antarctic America, Mchmo- 

 phorus major, figured in 'The Field' of November 18th; and a living
