of the jaw. Another skull from the same source, showing 

 remarkable sutural development, was also exhibited. Atten- 

 tion was also directed to two artificially distorted skulls from 

 Southern New Britain — a tight wrapping around an infant's 

 head induces an elongated skull. In one of the exhibits the 

 supraorbital region had been included in the wrapping and 

 the ridges had not developed in consequence ; in the second 

 head the eyebrows had not been included in the wrapping, 

 and the supraorbital bones had therefore grown to more 

 normal condition. Capt. S. A. White showed ten specimens 

 of Platycercus. Two were from the type locality of P. elegans 

 fleuriensis, Ashby, one being the typical dark red of the old 

 birds, the other a light phase. Two from Myponga, a few 

 miles north of the above locality, have been classed as P. 

 elegans adelaidensis, one being in the green immature 

 plumage. Two from the Adelaide plains are very bright 

 birds. One from Mount Pleasant is also a very bright bird. 

 One from South Para is much lighter. Two from Mount 

 Remarkable are of a decided pale form, and have been looked 

 upon by some ornithologists as being more closely allied to 

 Platycercus fiaveolus than to P. elegans adelaidensis ; with 

 this he did not agree, for to his mind this form partakes more 

 of adelaidensis than fiaveolus. He also showed a stone from 

 slate outcrops at Mount Remarkable, ripple marked, showing 

 that it had been deposited in shallow water. Mr. F. R. 

 Zietz showed a pink-eared duck ( Malacorhyncus membra- 

 naceus) from the Lower Murray. Mr. E. Ashby showed a 

 pyrites concretion from the Tapley Hill slate.
