154 MR. H. CHARLTON BASTIAN'S MONOGRAPH 
“Am unteren Ende des Pharynx liegen auf diesem zwei schönblaue nierenfórmige 
Augen. i 
* Lünge des Weibchens 6 Mm., Breite 0:2 Mm. 
* Länge des Männchens 4 Mm., Breite 0:2 Mm. 
* Oesophaguslänge verhält sich zur Körperlänge wie 1 : 5." 
This also cannot belong to the genus Enoplus. The first glance at Eberth’s figures 
reveals a large pharyngeal cavity with no teeth or jaws, a distinct cesophageal ring, and 
an absence of the characteristic supplementary male organ, which at once negative its 
really belonging to this genus, It seems to be a most remarkable and interesting type, 
but one with which I am quite unfamiliar.

Miiller’s Archiv, 1853, p. 431.—Eberth, Untersuch. über Nemat. p. 31. 
Under this name Berlin appears to have included two or three forms which are per- 
fectly distinct from one another. From his drawings, one of these animals is un 
doubtedly an Hnoplus, whilst another appears to be a Leptosomatum.

This animal is evidently not an Enoplus.
