Genital organs. — Xo genital organs can be discovered, so that the 
conclusion is drawn that the specimen is immature. 
C ross section. — Advantage was taken of the fact that the specimen 
is in fragments to prepare transverse sections (fig. 26 ) of the end of 
one of the pieces. A careful histological study of the slides is pre- 
cluded by the condition of the material. Xevertheless. some hnpor- 
tant anatomical observations are possible. 
The cuticle consists of concentric layers. A subcuticula can also be 
distinguished more or less clearly. The muscles are divided into six 
fields. sejDarated by the six longitudinal lines, but the finer structure 
of these lines can not be interpreted safely. 
In view of the foregoing data it appears that Filaria restiformis 
should be transferred from the Filar iidce to the family JFermithidce. 
as Agaraoraerinis restiformis. Further, the idea that an error has 
occurred in interpreting this worm as a parasite of man seems to gain 
support, for it would be exceedingly difficult to explain the presence 
of a GFerniitliidet in the bladder.
