differing topics have been brought before themembers, such as 

 colour in the lower animals, conchology, entomology, and rock 

 sectioning. 



The exhibits at these meetings have, as usual, been varied and 

 interesting — birds, shells, plants, and insects forming the greater 

 proportion. Amongst the exhibits may be mentioned the rare 

 shell, Acanthochites Matthewsi, from Marino, and the local one, 

 Adamsia Adelaides, from North Arm ; the scale insect, which 

 produces the manna found on Eucalypts ; birds and plants from 

 Nackara, not to be found near Adelaide ; and beetles from 

 various parts of the world. At one meeting it was mentioned 

 that practical observations showed that the garden flowers, 

 Kennedya nigricans and Cliantkus puniceus were probably fer- 

 tilised by the agency of birds.

The foregoing list includes two whole-day excursions, and 

 embraces some fresh localities. The longest trips were those to 

 the country between Highercombe and the River Torrens (near 

 its junction with Kangaroo Creek), and the Barossa Waterworks, 

 both places being visited for the first time by the section. The 

 walk down the River Sturt between Blackwood and Darlington 

 took in some of the scene of Mr, W, Howchin's recent 

 investigations in regard to the interesting Cambrian Glacial Age 

 discoveries. In this connection it may be mentioned that in the 

 Section's Reports for 1893-4 it is recorded that rock formation 

 noticed at an excursion to the River Sturt on May 12th, 1894, 

 were ascribed by Mr. J. G. O. Tepper, F.L.S., to the Pre-Cam- 

 brian age, and special reference to the specimens then collected 

 was made at the next evening meeting— M?y 15th, 1894.
