This paper, which has been published in full by the Geological Department, (" Palseon- 

 togogy of New Zealand," Part IV., 1880.) gives the results of an examination of a large 

 series of fossils belonging to this class, exhibited in the New Zealand court at Sydney 

 Exhibition by the Geological Department, and was illustrated by a beautiful series of 

 drawings made by the author. Three genera and thirty species were described as new 

 to science. 



Dr. Hector pointed out this investigation confirmed the view that during tertiary 

 times the climate of New Zealand had not been much different from that at present 

 prevailing, if anything it was a little warmer, and was quite opposed to the idea of a 

 glacial period having affected these latitudes. It also confirmed the classification he had 

 adopted in placing the Oamaru beds as upper eocene, and equivalent to the Mount 

 Gambler beds in Australia, and Table Cape beds of Tasmania. 



3. "On certain Minerals collected during the past Year by the Geolo- 

 gical Survey Staff," by S. H. Cox, F.G.S. 



ABSTRACT. 



Specimens were exhibited and described, some of which were of considerable value 

 and interest. Among them the following were announced as having been found in New 

 Zealand for the first time: — Crome mica, and hauerite, or sulphide of manganese. 

 Both these minerals were collected by Mr. McKay in the highly mineralized district lying 

 to the N.W. of Otago, where he also found lodes containing specular iron, pyrrhotine or 

 magnetic pyrites containing nickel, mispickel or arsenical pyrites containing gold, and 

 scheelite or tungstate of Ume, the latter having only been found as rolled fragments 

 hitherto. Several new discoveries of copper ore were also announced, among which was 

 occurrence of metallic copper in the basaltic rocks at the Manukau Heads, Auckland. 

 Also the occurrence in the trachytic dyke rocks at Tokatoka, Kaipara, of the zeolites, 

 natrolite, and stilbite. 



/ :, Dr. Hector exhibited and explained a copy of the geological map of New Zealand, 

 which he had prepared for the Melbourne Exhibition, giving a particular account of the 

 country geologically examined during the past year, and said that few were aware of the 

 amount of labour and great hardships that had to be undergone in carrying on the survey 

 in the more remote parts of the country. He gave a brief account of the progress of the 

 geological survey from its commencement, and showed that by degrees we have attained a 

 tolerably correct idea of the general structure of the whole country. There is still, 

 however, a great deal to be done towards the accurate mapping of the formations, and 

 particularly tracing those strata which indicate the presence of deep-seated coal seams, 

 and the high level auriferous cements to which he had referred at the last meeting.

On the " Colour-Sense," by Dr. G. Gillon. 



This was a lecture on the gradual development of the Colour- Sense in the Animal 

 Kingdom, and the corresponding evolution of the chromatic characters characteristic of 

 species of animals and plants.
