were covered by the mud and sand of the rivers. This holocene 

 deposit is so extensive that it is regularly quarried, and forms the 

 surface of the country roads and railway tracks wherever a surface 

 has been attempted at all, and that is only here and there. As the 

 country roads (like those in the United States) are merely tracks 

 across the open country, and without any bed or metalling, they are 

 often impossible for pedestrians after a heavy shower. In such case, 

 one walks along the railway track, which in one place is the only 

 road at any time. 



The following is a list of all the species I could separate ; they are 

 all extant on the Argentine coast. 



Voluta colocynthis Chem. 



V. angulata Swains. 



BuUia deformis King. 



B. cochlidium Kiener. 



Mactra sp. ? ) These two species formed the principal part 



Venus sp. ? J of the mass. 



Solecurtus platensis. 



Tagelus gibbus. 



The famous Museum at La Plata is surprisingly weak in Argentine 

 mollusca ; its chief feature being, of course, the unique series of 

 Gh'pfodons, which, by the courtesy of the Director, I was permitted 

 to photograph. 



From the Plate we proceeded to Durban, where I had absolutely 

 no success with the land and freshwater species. The well-known 

 rocks and beach on the south side of the harbour, however, provided 

 an interesting haul of Paieihe, Fissiirelhe, Cerit/iia, etc. Very numer- 

 ously strewn along the beach were the beautiful Carolina gibbosa and 

 Creseis acicii/a, mostly in perfect condition in spite of their extreme 

 fragility. 



From Durban we went to Bombay, where, from an exclusively 

 conchological point of view, we arrived at the best time of the year 

 to find land and freshwater species, viz., during the South West 

 Monsoon, when the earth is moistened and pools form. On this 

 occasion the earth was quite sufficiently moistened for my purpose, 

 for during the night of our arrival thirteen inches of rain fell in 

 eleven hours — a record that even Manchester might be proud of. 

 I spent much time in the Natural History Museum, which is an ideal 

 provincial museum, the exhibits being restricted to the fauna of the 

 country, and arranged on British Museum lines. The collections are 

 copiously labelled, and immaculate as regards dust and mould. I 

 owe much to the Curator, Mr. Kinnear, and the Secretary of the 

 Bombay Natural History Society, Mr. Millard, for the trouble they
