 Captain S. A. White showed a White-breasted Cormorant 

 (Hypolencus fuscescens) from Little Althorpe Island; also 

 two Pied Cormorants (Hypoleucus varius hypoleucus), one 

 in breeding, the other in non-breeding plumage, both females, 

 one from the Coorong, the other from the mangroves north 

 of Port Adelaide; also two tubes of parasitic worms, one 

 from a cormorant's stomach, the other from the thick coating 

 of fat covering its abdomen; also eight rounded stones, one 

 of granite and seven of sandstone, and shells of four species 

 of molluscs from a cormorant's stomach, doubtless swallowed 

 to aid digestion. Mr. A. M. Lea exhibited a drawer of 

 weevils of the genus Leptops, many of which attack wattle 

 trees, and a few of which have become very destructive to 

 apple trees and vines in South Australia, Victoria, and New 

 South Wales, through the larvae boring into the roots.
