12 NOTES AND COMMENTS [sULY 
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 Metadoxides, characterised by a conical 
glabella as distinguished from the club-shaped glabella of the older 
genus Paradoxides. The glabella is conical in Dr. Matthew’s new 
species from the Lower Cambrian beds of Newfoundland, and he 
describes it under the name Metadoxides 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 Metadoxides. 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 Metadorides 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 
Paradovides 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 Olenopsis, but also with Catadoxides, Metadoxides, Ana- 
doxides, the three sub-genera or infant progeny of MJetadoxides, with 
the second child endearingly named after its parent.
