fuch an appeafance originating from the union of the ends of two of the fila- 

 ments, each of which becomes geniculate at the beginning of the connection, 

 and thefe ends are moft commonly nearly of the fame length. Other parts of 

 the filaments are alfo frequently and fometimes repeatedly connected with each 

 other, in the fame manner, and I have feen fome which at firft fight bore a 

 ftriking refemblance to a mefli of C. reticulata. I feel myfelf at a lofs even to 

 offer a conjecture on the nature of this fingular union of the filaments, and can 

 only remark that they do not appear to effect any alteration in the interior of the 

 joints, as is the cafe with C. jugalis, bipun£tata and their congeners. "When the 

 juices have a little collapfed by drying, the tubular ftructure may be readily 

 obferved. 



C. mirabilis, in drying, adheres to both glafs and paper. 



A. C. mirabilis, natural fize. 



B. Ditto magnified 3.
