NOTES AND EXHIBITS. 



The President, on behalf of Mr. B. Jardine, of Somerset, 

 showed a fine pearl adherent to a valve of the pearl-shell. 



Mr. Froggatt exhibited a series of stages in the life-histor}'- of 

 the Mexican Cotton Boll Weevil {Anthonomis grandis) mounted 

 for educational purposes. Also specimens of the larva of a 

 water-beetle and a Nematode worm (Gordius sp.) found in the 

 stomach of a trout from Cooma, N.S.W. 



Mr, W. S. Dun exhibited a specimen of Lingida (sp.nov.) from 

 the Lower Marine Stage of the Permo Carboniferous at Ravens- 

 field, near West Maitland. The form appears to be more closely 

 allied to certain Silurian species than to those of the Upper Palaeo- 

 zoic. J. D. Dana recorded L ohovata from the Upper Marine 

 Stage of Gerringong (Geology Wilkes' Exped.). The genus is 

 apparently rare in the Permo-Carboniferous. 



Mr. Maiden exhibited specimens of the roots of the Native 

 Cherry (Exocarpus cupressiformis) showing haustoria. 



Dr. J . B. Cleland exhibited a series of anatomical specimens in 

 illustration of his remarks on the lUawarra Red-water of cattle. 

 This disease is confined, and seems peculiar, to the southern 

 coastal districts of New South Wales. It is popularly called 

 Red-water, or (to distinguish it from the Red-water due to the 

 organism transmitted by cattle ticks) South Coast Red-water. 

 The use of the term " South Coast Red- water" is apt to confuse 

 it with somewhat similar diseases, as regards the colour of the 

 urine, occurring in South Africa. Illawarra Red-water, therefore, 

 would be a better name. The disease may be described as a 

 haematuria due to the bleeding from multiple, muriform, telean- 

 giectatic growths in the bladder, with consequent secondary 

 anaemia, followed by accidents due to clotting of the blood in the 

 bladder, and subsequent bacterial infections, &c. From the 

 absence of signs of bacterial infection of the bladder in early 

 cases from the failure to find any parasitic worm, such as Bilharzia,
