NOTES AND EXHIBITS. 167 



Mr. Whitelegge exhibited a set of herbarium specimens of 

 British species of the genus Equisetum. Also, under the micro- 

 scope, specimens of the Peridinium, to the presence of which the 

 recent discoloration of the waters of the harbour has been due ; 

 also specimens of several other species of allied organisms, includ- 

 ing a second species of Peridinium, Prorocentrum micans, Ehr., 

 Gymnodinium sjrirale, Bergh, and Glenodinium sp. 



Dr. Cobb exhibited an inexpensive dissecting microscope of 

 simple construction, made by one of the clerks in the Agricultural 

 Department, Sydney. Also, under the microscope, examples of 

 the Nematodes described in his paper. Also, two examples of 

 fungi, one a species of Phallus from the adjoining garden, the other 

 the bird's-nest fungus, Cyaihus, from soil near a pumpkin vine ; 

 and coloured drawings of a number of other Australian fungi 

 which he had recently met with. 



Mr. Fletcher exhibited three specimens of terrestrial Nemer- 

 tines (Geonemertes sp.) — one from the Richmond River, N.S.W. 

 (collected by Mr. R. Helms), the others from Tasmania (collected 

 by Mr. C. Hedley). The Tasmanian forms seem to diner in colour 

 and pattern from the Victorian specimens recorded by Dr. Dendy 

 and Professor Spencer, Mr. Hedley describing them while alive as 

 " black at the oral extremity for about a quarter of an inch, the 

 rest of the body dull white." The New South Wales specimen 

 may, perhaps, belong to the same species as those noted by Dendy, 

 the colour being brownish-orange, except for a lateral band on each 

 side. If G. chalicophora, Graff, like G. palaensis, Semper, has six 

 eyespots, in two groups of three each, then the specimens exhibited 

 to-night, in which more than six eyespots are present, are not to 

 be identified with the former, which is supposed to have been 

 brought with palms from Australia to the palmhouse at Frankfurt 

 Zoological Gardens. 



Also, a male specimen of Peripatus leuckarti, Sang., (the only 

 male out of a total of five specimens obtained on the Blue Moun- 

 tains), which presents the exceptionally remarkable character of 

 possessing a pair of papillae — the only pair present, — on the ventral 

 surface of the first par of legs.
