A discussion of certain questions of nomenclaturc, as ajiplied to parasites. 185 



In Order to aid the bibliographer in every way to clearly dis- 

 tingiüsh the authors, it is well always to give the more or less com- 

 plete name; thus, to take illustrations : ''Richard Heymons, Assistant, 

 Zoological Institute, Berlin, Gerraany" is better than ''R. Heymons, 

 Berlin"; "Max Braun, Professor of Zoology, Königsberg i. Pr." is 

 better than "M. Braun, Königsberg i. Pr."; "Raphael Blanchard, 

 Professor of Natural History, Paris Medical School" is better than 

 "R. Blanchard, Paris", etc. 



3) If reprints are to be distributed, the author should impress it 

 upon the publisher that a) the original pagination should be retained; 

 b) the printed matter should not be shifted; c) the reprint should 

 also bear the name, volume, number, and the date of publication of 

 the Journal. 



Attention may be called to the reprints now issued by the Zool. 

 Anzeiger and the Centralbl. f. Bakter., Parasiteukunde u. Infektions- 

 krankheiten, which may be taken as modeis. The custom followed by 

 many medical Journals — particularly American — is not to be com- 

 mended ; the printed matter is shifted and the article is repaged from 

 1 — X, with no indication of the original pagination. 



4) If a new genus or a new species is proposed, the fact should be 

 brought out clearly by the use of prominent type as a heading or 

 subheading. Looss' article may be consulted as a model. Proposing 

 a genus in the text (and even then not adopting it himself), as Looss 

 did in 1896 {Leciihodendrium, Pleurogenes, and Prosthometra)^ or as 

 he has done in 1899 {Änadasmus), or as Braun, 1899 {Paragonimus, 

 Phyllodistotnum, Harmostomuni), and Luhe, 1899 {Telorchis, Prostho- 

 gonimus, etc.), and others have recently done, is calculated to lead 

 readers to overlook them and thus to lead to later confusion, hence 

 this method should be strenuously avoided. 



There can not be the slightest doubt but that scores of names 

 so proposed have for the time being been overlooked, and later, on 

 being suddenly discovered, have resulted in unfortunate changes in 

 nomenclature ; take Eemiurus Rudolphi, for instance. 



Some authors follow the very commendable plan of giving a com- 

 plete index to all the scientific names in their article, and placing the 

 new generic and specific names in bold type. Other authors follow an 

 excellent plan of giving a list of the new genera and species mentioned, 

 and this latter plan is adopted by some societies in their proceedings (cf. 

 Soc. Zool. France); The Washington Biological Society adopts the 

 former plan.
