from Mr. Savage) a minute blind beetle, of the genus 

 Rodwagia, occurring in the nests of ante, and now first 

 recorded from South Australia. Mr. Edgar R. Waite 

 showed a photograph of a hat from New Britain, eight feet 

 in diameter, which is worn by two men at once. Capt. S. A. 

 White showed live and dead specimens of the old English 

 black rat, recently introduced from Egypt, and now doing 

 serious damage in our orchards. During its sojourn in Egypt 

 for many generations it has become much lighter in colour. 

 He also showed photographs exemplifying its ravages. Mr. 

 F. II . Zietz showed some tear-drop shaped obsidianites, from 

 the Diamantina ; also tracings of aboriginal pictographs, from 

 two rock shelters at Yattalunga, in the valley of the South 

 Para River, near Smithfield, sketches of some of which had 

 been previously published in vol. xxvi. of our "Transactions/' 

 and, in addition, a jaw of a bandicoot, freshwater mussels 

 (Unio sp.), and fragments of emu egg shell found amongst 

 the ashes and sand on the floor of one of the shelters. Capt. 

 S. A. White showed photographs of the locality of these 

 shelters, and urged that action should be taken to preserve 

 them. 



Resolved. — "That the Council be requested to consider

Nomination. — John F. Bailey was nominated a Fellow. 



Election. — Charles A. E. Fenner, D.Sc, F.G.S., was 

 elected a Fellow. 



Exhibits. — Mr. Edwin Ashby exhibited a number of 

 Polyplacophora (Chitons) collected by himself at Port Lincoln. 

 Amongst these was a very carinated specimen of Ploxiphora, 

 which he believed would correspond with the description of 

 the lost Ploxiphora conspersa, described by Adams and Angas 

 from specimens collected at Port Lincoln. The less carinated 

 form described by Tom Iredale as P. matthewsi, of which 

 several specimens from Port Lincoln were shown, is, in Mr. 

 Ashby s opinion, only a variety of Adams and Angas' P. 

 conspersa . The type form is evidently much rarer than the 

 variety, as only two specimens were obtained by Dr. Torr, 

 who was collecting with him, and one by himself. The
