1883 was from Otis macqueeni, collected in Turkestan by Professor 

 Fedtschenko; the 1906 specimens were described as a new species 

 from Otis houbara, in the Zoological Museum at Konigsberg. 

 Seurat (1914;117) found Filaria rotundata Linstow, 1883, in Hou- 

 bara undulata in Algeria ; he redescribed it and placed it in the genus 

 Habronema and later (1915 ;14) transferred it to his new genus 

 Hartertia. Skrjabin (1916 ;501) found this same nematode in Rus- 

 sian Turkestan in Oedicnemus oedicnemus. 



Physaloptera rotundata Linstow, 1906 was transferred to Hab- 

 loneina by Seurat (1914; 153) but he gives the locality of collection of 

 the nematode as Algeria and Turkestan, which is not that of the 1906

species but of Linstow's earlier species, Filaria rotundata Linstow, 

 1883. 



In order to straighten out the confusion caused by this use of the 

 same specific name by the same author at different dates, the present 

 writer has renamed the species and placed it, at least provisionally, 

 in the genus Hartertia. The description as given by Linstow makes 

 no mention of certain characters included in the generic diagnosis of 

 Hartertia, as the trilobed division of the inner surface of the lips, 

 but the species seems to be quite similar to Hartertia obesa, the type- 

 species of the genus. 



This species, renamed Hartertia confusa, synonym Physaloptera 

 rotundata Linstow, 1906, differs from Hartertia rotundata (Linstow, 

 1883) in the size of the body (H. confusa being less than half the 

 length of the smallest specimens of H. rotundata), in absence of 

 lateral alae, in a somewhat more anterior position of the vulva, in 

 the much smaller size of the eggs, in different spicule lengths, width
