NOTICE TO THE ZOOLOGICAL PROFESSION OF A POSSIBLE SUSPENSION 

 OF THE INTERNATIONAL EULES OF ZOOLOGICAL NOMENCLATURE 



IN THE CASES OF MuscA Liniiacus, 1758, & cALLiPHORA Desvoidv, isso. 



In accordance with the Rules of the International Zoological Congress, 

 the attention of the zoological profession is invited to the fact that Dr. 

 L. O. Howard, W. Dwight Pierce, and 21 other professional zoologists 

 have requested the International Commission on Zoological Nomencla- 

 ture to exercise ,its Plenary Power in the case of the Linnaean c^enus 

 Musca 1758， and, under suspension of the Rules, to declare M domeS' 

 tica as type of this genus, also, under suspension of the Rules, to validate 

 Calliphora Desvoidy, 1830, with C. vomitoria as type. 



The request is based 011 the grounds of practical utility, and an almost 

 unbroken, history of consistent usag-e since 1758 in the case of Musca, 

 and since 1830 in the case of Callipiiora It is claimed that a strict 

 application of the Rules will produce greater confusion than uniformity. 



According to the premises at present before the Commission, if the 

 Rules are strictly applied, the generic name of Musca would take either 

 M. caesar or M. vomitoria as type, and the species M domestica 

 would be cited either in Conostoma 1^0 1 [？] (type Ascaris conostoma 

 ^ larva of M domestica) or in Conosoma 1802 (type Ascaris cono- 

 soma 二 larva of M- domestica) or in Fronmsca 1915 (type M. 



domestica)? thus resultino- in a very regrettable chancre in the nomen- 

 clature of the species in question as almost universally used in entomo- 

 logical, medical, epidemiological, and veterinary literature. 



The Secretary of the Commission invites any person interested in these 

 cases of nomenclature to communicate his opinion 011 the subject as soon 

 as possible, and not later than May I, 1918, when the subject will be 

 submitted to the Commission for vote. 



C. W. Stiles, 



Secretary to Commission,
