Bemerkenswert ist die Übereinstimmung, welche in bezug auf das 

 Ende der Phorocyten zwischen Änchiiiia, DoUolum und Dolchinia einer- 

 seits und Pyrosoma anderseits besteht. Hier wie dort degenerieren die 

 Zellen, und deshalb lassen sich z. B. bei DoUolum (Neumann 1906) die 

 gleichen Bilder beobachten: An fixierten Knospen allenthalben jene 

 stark verlängerten, äußerst intensiv färbbaren Kerne.

Abstract of Proceedings, May 26 th, 1909. — Mr. Frogatt exhibited 

 a series of stages in the life-history 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 Lingula (sp. nov.) from the Lower Marine Stage of the Permo- 

 Carboniferous at Ravensfield, near West Maitland. The form appears to be 

 more closely allied to certain Silurian species than to those of the Upper 

 Palaeozoic. J. D. Dana recorded L. obovata from the Upper Marine Stage 

 of Gerringong (Geology Wilkes' Exped.). The genus is apparently rare in 

 the Permo-Carboniferous. — Dr. J. B. Cleland exhibited a series of ana- 

 tomical specimens in illustration of his remarks upon an obscure disease 

 affecting stock in the Southern Coastal districts of New South Wales, 

 populary called Red-water, or South Coast Red-water (to distinguish it from 

 the Red-water due to the organism transmitted by cattle ticks), but for which 

 the name. Ilia warra Red-water was suggested. The disease may be described 

 as a haematuria due to the bleeding from multiple muriform teleangiectatic 

 growths in the bladder, with consequent secondary anaemia, followed by 

 accidents due to clotting of the blood in the bladder, and subsequent 

 bacterial infections, etc. From the absence of bacterial infection of the bladder 

 in early cases, from the failure to find any parasitic worm, such as Bilharxda^
