South Brisbane. Dr. Knight makes the following remarks: — 

 " It is a beautiful object under water, protected by a thin glass 

 cover, with H inch object-glass. (Fig. 2; a.) It agrees closely 

 with one collected by Dr. Schweinfurth in the country of the 

 Niam Niam, in central Africa (Schw. 2969; Arnold's Exsicc. 

 No. 818.) I possess another specimen collected in tropical 

 South Amei-ica by Spruce, No. 640. The last mentioned has 

 the margins of the lacini^e regularly toothed. This, however, 

 is not the case with the Queensland Lichen ; altho' it would be 

 seen in the accompanying diagram that three or four teeth are 

 sometimes found on the edge of the laciniae (fig. 2, b.) The 

 long hairs (fig. 2, c.) bearing at their apex remarkable capitula 

 containing endochrome, are very numerous, but are scarce in 

 the South Ameiican specimen. The silvery glistening appear- 

 ance of S. Nemathora, under the microscope, is due to the pen- 

 nate veined structure of the laciniae, which l eflects the light in 

 a remarkable manner. Hence, probabl}", Fee's name, Nematora 

 arge7itea.''
