presented by the Trustees of the British Museum, and by the Copenhagen 
Museum through Captain Rowan. 
Minerals.—620 specimens have been added, which number includes a 
large series obtained in exchange from the British Museum, and selected by 
direction of Professor J. Storey Masklyne, F.R.S., in order to make as 
complete as possible the typical collection, which now contains representa- 
tives of every important mineral species. A valuable series, comprising 109 
species of ores and associated minerals from the Californian mining region, 
was received from Mr. H. G. Hanks, which, with the large collection of 
specimens brought by the Director from the Colorado and Utah regions, 
affords a very complete illustration of the metalliferous deposits of the 
Western States. 
Paleontology.—Among the foreign collections in this section is a valu- 
able donation from Mr. James Brogden, of a series of the Saurians from 
Lyme Regis, and the associated Triassic fossils. 
For the purpose of comparison, casts of 800 of the best fossil specimens 
in the European and American Museums were obtained through Professor 
H. A. Ward. 
Geological Survey Collections.—During the present year.a special exami- 
nation has been made of the fossiliferous beds of the Waikato Heads, with 
a view of determining their age and tracing their extent. A considerable 
collection of fossils was made from the loeality, but the number of distinct 
forms obtained is small. 
An important collection was made from certain blue clay marls oceur- 
ring at the mouth of the Waikauau Creek, about fourteen miles south of 
the Waikato Heads, as an upper part of the grey marls not yet detected 
elsewhere, and which will be referred to as the ** Cardita Beds," from the 
abundant occurrence in them of Cardita planicostata, a well-marked Lower 
Eocene fossil in Europe. 
These beds had formerly been classified as the equivalents of the Waite- 
mata beds as developed at Mercer, but the collections now obtained from 
each of these localities, in addition to stratigraphical evidence, make the 
separation of these two necessary, the Mercer beds belonging to the chalk 
marls. 
In the Oamaru District six very important collections have been made, 
in addition to several smaller ones, and the evidence gained renders it 
necessary to readjust the classification of the beds adopted by Captain 
Hutton in his ** Geology of Otago," his Trelissie group being in part the 
same as his Pareora group; while, on the other hand, many localities con- 
Sidered by him to belong to his Pareora formation, to his Trelissie forma- 
tion, and the whole of his Ototara group, will, from the fossils, have to be
