12 NOTES AND COMMENTS [jult 



and Irish Botanists. It includes the botanists who died between 

 January 1, 1893, and December 31, 1897, and also several who were 

 omitted from the original Index, comprising together about 250 entries. 

 There are a few well-known names, such as Babington of Cambridge, 

 Huxley (whose claim as a botanist rests on a paper on gentians), 

 Williamson, the expositor of the plants of the coal-measures, Bentley 

 of the Pharmaceutical Society, his one-time associate author Trimen 

 of Ceylon ; but the great majority are not widely known, and many 

 are to hand only as the result of painstaking research. By recording 

 so many of these obscure, but often extremely useful workers, the 

 authors of this Index have rendered a lasting service to Botany, and 

 we shall hope for a regular recurrence of the supplement as time and 

 botanists pass. 



A New Found Trilobite from Newfoundland. 



The trilobite which Dr. G. F. Matthew has recently described in the 

 Bulletin Nat. Hist. Soc. New Brunswick (vol. iv. No. 17, 1899) is of 

 considerable size. The head shield is more than six inches wide, 

 and the movable cheek with its greatly produced genal spine is about 

 seven inches long. Its principal interest appears to consist in its 

 supplying " a new link between the Cambrian of Europe and that of 

 America." For certain Cambrian trilobites discovered in Sardinia, 

 Bornemann founded the genus Mctacloxicles, characterised by a conical 

 glabella as distinguished from the club-shaped glabella of the older 

 genus Paradoxicles. The glabella is conical in Dr. Matthew's new 

 species from the Lower Cambrian beds of Newfoundland, and he 

 describes it under the name Metadoxicles magnificus. But he urges 

 that it is a more primitive member of the genus than the Sardinian 

 species, and, moreover, that Paradoxides, though older in name, is not 

 older in nature than Metadoxidcs. He gives reasons for supposing that 

 trilobites migrated from New Brunswick through Newfoundland to 

 Southern Europe. To emphasise his views on the succession in time 

 of various species, at the close of his article he proposes to divide the 

 genus Mctadoxides into three sub-genera, the first and eldest being 

 Catadoxides, with the new magnificus for its exemplar. The late 

 Henri Milne Edwards refused to accept the separation of Olenus from 

 Paradoxides as a needless new-fangled addition to overburdened 

 nomenclature. We can imagine, therefore, how charmed he would 

 have been to be confronted not only with Olenus and Protolenus, and 

 Olenellus and Olcnopsis, but also with Catadoxides, Metadoxicles, Ana- 

 doxides, the three sub-genera or infant progeny of Metadoxicles, with 

 the second child endearingly named after its parent.
