A memoir on the tubulose Polymorphinse, of which there are sixty-nine known forms, has lately 

 been communicated to the Linnean Society by T. E. Jones and F. Chapman. They define five groups, 

 namely: (1) with " apical " growths (divisible into five sub-groups, — formae damsecornis, coronula, 

 acuplacenta, horrida, et racemosa) ; (2) " subapical " growths (forma circularis) ; (3) " on general 

 surtace " (forma diffusa) ; (4) " marginal" (forma marginalis) ; (5) " mixed kinds of growths " (forma 

 complicata).
