l4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 'J'}^ 



The following extract from the Contribution under consideration 

 will serve to give a conception of Danilewsky's viewpoint : 



(P. 762) Nous aliens passer maiiitenant a I'etude du microbe de I' infection 

 malarique aiyuc. II doit etre distingue de celui de la forme chronique. Tous 

 les microbes de nature animale vivant et se developpant a I'interieur des cellules 

 sent ordinairement appeles cytozoaires, cyto-parasites ou cyto-microbes. Ces 

 noms indiquent le lieu 011 ils se trouvent. En me conformant a cette nomen- 

 clature, j'ai propose de remplacer la denomination du Plasmodium malarique de 

 I'homme, Haemamaeba, en celle de Cytamaeba. Mais comme chez les oiseaux 

 le meme parasite, n'etant pas mobile, n'a pas de caractere amiboide, ce nom 

 d'amaeba ne pent lui etre applique. Aussi, et surtout a cause de la propriete 

 fondamentale du microbe de donner des spores, je I'appellerai Cytosporon 

 malariae} 



(P. 780) Au point de vue de I'hypothese unitaire de I'infection malarique on 

 pourrait proposer le rapprochement suivant des diverses formes du parasite, 

 sans entrer pour cela dans la discussion de sa place dans le systeme zoologique :

Thus two generic names are used by Danilewsky on page 762 for 

 what he designates " le meme parasite." 



The table of designations given on page 780 is subject to various 

 interpretations. Under the most favorable interpretation Danilewsky 

 recognizes one species, Cytozoon malariae with 2 varieties or sub- 

 species, hominis and avium, and attempts to harmonize early names 

 with his nomenclature. Even this interpretation, however, does not 

 leave the reader clear as to the author's intention ; possibly he con- 

 sidered earlier names as inappropriate and substituted for them the 

 generic name, Cytamaeba ; then, considering this latter inappropriate. 

 he appears to have substituted for it Haenwcytosporon which he con- 

 tracted to Cytosporon. 



During the past thirty years the Secretary has repeatedly endeavored 

 to interpret the nomenclature of Danilewsky's Contribution, but 

 is unable to reach a conclusion which he considers in harmony with the 

 rules of any code of nomenclature in effect at present or at date of 

 publication of said Contribution or prior thereto. In conference with 

 other zoologists, the Secretary has learned that they also find the same 

 difficulty in interpreting said Contribution. 



The Secretary invites the attention of the Commission to the fact 

 that there is an enormous accumulative economic loss in science result- 



' On ne doit voir dans ce nom provisoire (abrege de Haenwcytosporon) 

 aucune allusion a une parente de ce microbe avec les champignons, les monades 

 ou les mycetozoaires. Sa classification zoologique sera discutee plus loin.
