DERIVATION OF THK FLORA AND FAUNA 297 



a secoiul will ha\c to he described — is ciideiiiic and se\eral lia\e a wide distri- 

 hiition. 



The scant kiu)\vled«^e of this nej^lected ^roiii) in tiiese regions, particular!)' 

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

 graphical speculations. Nevertheless it deserves to be mentioned that liuicrgvs 

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

 that P/iy///ien)U7nnur deutata Trag. is related to a neozelandic species; the genus 

 is also found elsewhere. 



Pseudoscorpionidea (/p). 



+ ^ AsteroclicDies rittalus Heier. — Mt. The genus has its greatest resemblance 

 to TltalassocJiernes Beier from New Zealand. 

 + Chelanops iusularis Beier. — Mt. 



■\-Ch. kiischeli Beier. — Mt. Related to a Chilean species. 

 + Geogarvpits biicciileiitus l^eier. — Mt. 

 "^ParacJu'Dics kuscJicli Beier. — Mt, Mf. 

 + + ProtoivirtliiHS fcnia}idezianus Beier. — Mf. 

 -vP. robustus Beier. — Mt. 



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

 AustralianT^olynesian 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 

 INIasafuera or Santa Clara — was studied by Verhoeff {214). In order to get some 

 information on the distribution of the genera I asked Dr. O'no ScilL'BART 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 Veriioeff, if different, have been 

 put in brackets. 



Diplopoda. 



Brachymlns pusillus Leach (Microbrachyiulus litoralis Verb.). Indigenous in 

 western Europe, adventitious in N. America and Argentina. 



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

 and Argentina. 



+ AulacodesmHS hisulanus (Verb.) Schubart (Semnosoma, Verb.). 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). 



Xopoiulns voiustus Meinert (pulchellus Leach). Widely distributed in Europe, 

 introduced to N. America and Chile. 



Cylindrohilus frisiiis oceaiiicus Verb. T\'pical frisius [C. Oweni Bollman) 

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

 Paul's I.
