4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 73 



Furthermore the genus Calliphora has found a place in medical and entomo- 

 logical literature with vomit oria as its type, and has remained stable for almost 

 a century. 



Musca domestica is one of the few insect species known the world around to 

 scientists and general public alike. The public at least will never know it 

 otherwise. The scientific fraternity will accept with the greatest reluctance the 

 chaos-making change. It is therefore that the following request is made of the 

 International Commission on Zoological Nomenclature. 



Action requested. — The signers hereby formally make application of the 

 International Commission on Zoological Nomenclature to place the combinations 

 Musca domestica Linnaeus and Calliphora vomitoria Linnaeus in the list of 

 Nomina Conservanda, thus definitely establishing domestica L. as type of 

 Musca, and vomitoria L. as the type of Calliphora. Robineau-Desvoidy definitely 

 stated that vomitoria Linnaeus was type of Calliphora, although he personally 

 studied a closely related species, possibly identical, which he mistook for 

 Linnaeus' species. 



This request is made on the ground of practical utility, universal usage, and 

 an unbroken history of consistent usage (with only two exceptions as above 

 noted), in the face of a perfectly legal procedure which causes confusion and 

 innumerable difficulties. 



Doctor Pierce's request for suspension of the rules is signed also 

 by 22 additional entomologists as follows : L. O. Howard, W. D. 

 Hunter, W. Dwight Pierce, F. C. Bishopp, R. H. Hutchison, U. C. 

 Loftin, W. E. Dove, Henry Fox, W. J. Phillips, B. R. Leach, F. L. 

 Simanton, A. J. Ackerman, J. B. Gill, Dwight Isely, Thomas E. 

 Snyder, F. R. Cole, Jacob Kotinsky, C. H. Popenoe, F. H. Chittenden, 

 W. B. Wood, A. C. Baker, W. R. Walton, A. L. Ouaintance. 



Discussion by Secretary. — In accordance with the provisions 

 governing the use of the Plenary Power by the Commission, the Sec- 

 retary gave formal notice to the Zoological Profession that these 

 cases would come before the Commission for consideration. See 

 (i) Monitore Zoologico Italiano 1917, v. 28, 183; (2) Ann. Mag. 

 Hist. No. 114, 1917, V. 19, 484; (3) Zool. Anz., Feb. 13, 1923, p. 46. 

 These notices have resulted in communications reaching the Secre- 

 tary as follows :
