Synonymy of some European Diplopods. 411 



( '. simile rhenanuvi, and as such I recorded them *. Examples 

 identified by EMingsen from Norway (a large series) were 

 all referred to simile (and subspecies and varieties thereof) 

 by Verhoeff (Zool. Anz. xxxix. pp. 499-511, May 1912), 

 whilst the G. rawlinsii ' recorded from Holland in moles' 

 nests by Father Heselhaus, S.J. (Tijdschrir't voor Ent. lvi. 

 1913, p. 240), was later (/. c. lvii. 1914, p. 80) referred by 

 Verhoeff: to simile. It therefore seems that no exam [ties of 

 what he regards to be rawlinsii have been examined by 

 Verhoeff from our faunal area, all so named being referred to 

 simile, and until the reverse is proved I consider ifc distinctly- 

 advisable to regard VerhoefFs simile as a synonym of raw- 

 linsii, Leach. In the meantime, it is to be hoped that more 

 British examples may be secured for study. 



Thus a new name is necessary for the rawlinsii of Verhoeff 

 (non Leach), but as Latzel gives the names marmoratum, 

 (J. K. (1847), and gibbosum, Am Stein (1857), as synonyms, 

 it would not be wise to suggest a new name without further 

 research, 



Craspedosoma leachi (nom. nov.), Bagn. 



Syn. Craspedosoma simile^ Attema (non Verhoeff), 1895, Sitz. k. 

 Akad. Wiss. Wien, math.-naturw. CI. civ. pp. 75-7(3. 



A species allied to mntabile, Latz. When Attems described 

 it he was aware of Verhoeff' s var. simile of rawlinsii, but the 

 raising of this form to specific rank rendered it necessary to 

 give another name to Attcms's species. 



Polymicrodon polydesmoides (Leach) . 

 Syn. Polymicrodon latzeli (Verhoeff ).

Atractosoma latzeli was described by Verhoeff in 1891 

 from the south of England, his description being based upon

pods new to the British Fauna," The Zoologist, July 1912.
