DERIVATION OF THE FLORA AND FAUNA

a second will have to be described — is endemic and several have a wide distri- 

 bution. 



The scant knowledge of this neglected group in these regions, particularly 

 in Oceania, is to be regretted; it certainly does not yet lend itself to zoogeo- 

 graphical speculations. Nevertheless it deserves to be mentioned that Euiergvs 

 similis Trag. belongs to a genus hitherto recorded only from New Zealand and 

 that Phyllhermannia deiitata Trag. is related to a neozelandic species; the genus 

 is also found elsewhere. 



Pseudoscorpionidea (jp). 



+ + Asterocherftes vittatus Beier. — Mt. The genus has its greatest resemblance 

 to Thalassochernes Beier from New Zealand. 

 + Chelanops insularis Beier. — Mt. 



+ Ch. ktischeli Beier. — ^Mt. Related to a Chilean species. 

 + Geogarypus bucculentus Beier. — Mt. 

 'V Parachernes kuscheli Beier. — Mt, Mf. 

 + + Protoivirthius fernandezianus Beier.- — Mf. 

 ^P. robustus Beier. — Mt. 



Neotropical elements are present, but species with their relatives in the 

 Australian-Polynesian region are in dominance and part of the fauna shows not- 

 able archaic characters (I.e. 205). 



Myriapoda. 



The very small and incomplete collection — no specimens were brought from 

 Masafuera or Santa Clara — was studied by Verhoeff {2^4). In order to get some 

 information on the distribution of the genera I asked Dr. Otto Sciiubart of 

 Pirassununga, Brazil, for assistance, and he most liberally put his wide knowledge 

 of this group at my disposal (letter, Aug. 27, 1954). Several changes had to be 

 made in the nomenclature; the names used by Verhoeff, if different, have been 

 put in brackets. 



Diplopoda. 



Brachyiulus pusilhis Leach (Microbrachyiulus litoralis Verh.). Indigenous in 

 western Europe, adventitious in N. America and Argentina. 



Brachydesmus supertis Latzel. A European species, adventitious in N. America 

 and Argentina. 



+ Aulacode sinus insulanus (Verh.) Schubart (Semnosoma, Verh.). Endemic. A 

 genus of 16 species, distributed over Chile and Argentina and belonging to the 

 austral family Sphaerotrichopidae (S. Amer., S. Afr., Madag., Nossi Be, Austral., 

 Tasm., N. Zeal., N. Caled., Hawaii). 



Nopoiulus veiiustus Meinert (pulchellus Leach). Widely distributed in Europe, 

 introduced to N. America and Chile. 



Cylindroiulus frisius oceanicus Verh. Typical frishis {C. O^veni Bollman) 

 introduced to N. America, Argentina (also in forma oceanicus), S. Africa and St. 

 Paul's I.
