NOTES ON THE SYNONYMY OF THE MYRIAPODA.* 

 Hy CiiARLKM Hakvky Bollman. 



1. I*OLYZONIIN,K. 



1841. — Omniophora Brandt. Kecneil, 49. 



1871'. — I'latijdeHmienH. MIhs. Soieutif. Mex., Zool., vi, 199. 



1884. — I'latydeainia (Saiiss. ( f ) ) Latzel. Myr. Ost. Uugar. Monarch., ii, 356. 



Placing Siphonophora and its allies in a separate subfamily leaves the 

 remaining genera as a similar group to which we must give the name 

 PoLYZONiiN^E, because it contains the type of the family Folyzoniidw. 



2. SlPHOXOPHORIN.«. 



ISM.— Typhlogena Brandt. Recueil, .W. 

 1844. — i)iphonophorid<r Newport. Trans. Linn. Soc, 278. 

 1869. — Andrognathido! Cope. Proc. Aiuer. Philos. Soc, 182. 

 1884. — DoliHtenia Latzel. Myr. Ost. Ungar. Monarch., ii, 362. 



Many writers have seen fit to detai^h Siphonophora from related 

 genera, and to make of it a separate family or subfamily. As no char, 

 acters of importance exist except those drawn from the form of body, 

 it seems best, therefore, to give it the rank of a subfamily only. 



To place Andrognathm Cope in this subfamily makes the number of 

 segments valueless as a subfamily character. 



3. Andrognathus. 



1869, — Andrognathus Cope. Proc. Anier. Philos. Soc, 182 {cortiearms), 



1875. — Dolistenus Fanzago. Atti Soc. Ven. Trent. Sci. Nat., 62 (sai-u)- 



1884. — Dolicho8tenu8 Latzel. Myr. Ost. Uugar. Monarch., ii, 68 (emendation). 



1884. — Dolysteniie Berlese. Acari, Myr. & Scorp. Ital., Fas. xii, No. 2 (emendation). 



A careful comparison of Andrognathus and Dolistenus has shown that 

 the two genera are inseparable, and the latter must stand as a syno- 

 nym oi Andrognathus. 



Dr. Berlese has used his emendation of Dolistenus in .all his works, 

 while Dr. Latzel's only occurred in a foot-note, and was intended to 

 show how Dolistenus should be spelled according to its derivation. 



4. POLYZONIUM. 



1834. — Polyzonium Brandt. Oken's Isis, 704 {germanieum). 



1836. — Platyuhm Gervais. Bull. Soc Phil. Paris, 71 (audouini=germanicum). 



1839. — Leiosoma Victor. Bull. Nat. Moscow, 44, pi. i {ro8ea^ germanieum).

 in character, it is believed to contain matter of sufficient importance to warrant
