under Tropidocerca inflata in 1861 but it was a one-line description 

 which is not recognizable. Linstow (1879a) says the material he 

 described in 1877 as Tropidocerca paradoxa is Diesing's Tropido- 

 cerca inflata. Since Linstow probably had access to the collections 

 in making his comparisons, and since we have no evidence one way 

 or the other, we must assume he is correct in saying he was dealing 

 with the same species as that of Mehlis, and accept his description 

 of it. 



However, at a later date (1899) Linstow states that T. paradoxa is 

 a synonym of Hystrichis papillosus (Eustrongylides papillosus) 

 while Jaegerskiold (1909) has listed both T. paradoxa Linstow, 1877, 

 and Hystrichis papillosus Linstow, 1899 in part as synonyms of

Eustrongylides elegans. Linstow's description and figures are un- 

 questionably of a species of Eustrongylides and agree with E. elegans 

 in all particulars except the length of the spicule. It follows there- 

 fore, from all the available evidence, that Microtetrameres inflata is 

 in reality a species of Eustrongylides and the present writer will not 

 include the description of it in the Tetrameridae but under E. ele- 

 gans, the latter, however, apparently also being synonymous with 

 E. mergorum (p. 372).
