Filaria gracilis, Rud. ; Cobbold, 1. c. p. 124, pi. xviii. figs. 1-4 
(Aides, omentum). 
Filaria sanguinea, Rud., (body cavity of Cyprinoids) is an Ichthyonema 
(of which a new generic characteristic is given) ; Linstow (6). Male 
very minute; as the female has no vulva, copulation probably takes 
place by piercing the skin of the female with the spicula ; the mature 
females probably perforate the intestinal wall of the fish, and pass with 
the excrement into the water, where they burst and set free their 
embryos. Asdli are perhaps their temporary hosts. W.-SuiiM (12) 
points out the analogies between Ichthyonema and Filaria medinensis. 
A note by Boettcher on Filaria medinensis, SB. Ges. Dorp, iii. (1872) 
pp. 275-277, records the observation of embryos in enormous numbers 
in the inflamed tissue in the immediate vicinity of the worm, a fact 
which explains the dangerous cases sometimes occurring. 
Filarioides belongs to the Polymyaria, Schn. ; Linstow (7).

Trichosoma crassicauda, Bellgh., is made the type of a new genus, 
Trichodes\\, by Linstow (8), distinguished by the want of bursa and 
spicule in the male, which is very minute and makes its way through 
the vulva into the oviduct of the female, during the passage of those 
organs from the ureters, at a time when the female is still relatively 
small; afterwards she increases in size, and several males take their 
abode in her interior. A large male Nematoid, found with Trichodes 
crassicauda in the bladder of the Norway Rat, is described as Trichosoma 
schmidti, sp. n.
