New Gordius from China.* — Prof. L. Camerano describes a new 
species of Gordiid from China, to which he gives the name of Chordodcs 
moutoni. It is distinguished from all allied species by its coloration, 
by the formation of the hinder extremity of the male, and by the general 
plan of the structure of the cuticle. 
New Filaria from Natal.j — Prof. G. Neumann describes a new 
Filarian found in Fythori natalensis, which has some affinities to 
F. medinensis. The new species is called F. dahomensis ; like its ally 
it lives in the connective-tissue near the skin, and the differences between 
the two are simply specific. The point of greatest interest is the 
discovery of the male of this new species, as the female of the other 
is alone known. It is probable that in both cases the male is exceedingly 
short-lived. 
Filaria papillosa.J — Herr C. Deupser made some experiments with 
a view to ascertain if embryos of Filaria joajpillosa isolated from living 
worms could be cultivated. The experiments were negative. The 
author found several times in horse’s blood small filarioid wormlets 
which in size and shape resembled the embryo of F. pajpillosa. This 
discovery suggested the notion of keeping the embryos in horse’s blood, 
and as they survived for 36 hours, it seemed probable that F. pajpillosa 
might pass its first transition stage in the blood. Pregnant female 
worms were then introduced into the abdominal cavity of rabbits, and 
numerous examinations of the blood showed the presence of the embryos 
in the circulation. Filaria papillosa therefore behaves as do F. Ban- 
crofti of man and F. attenuata and tricusjpis. of birds. The earliest time 
the embryos were detected in the blood was 34 hours, and the latest 
31 days. The further fate of the hsematozoa was not ascertained. 
Trichina Migration. § — Herr A. Geisse experimented on cats and 
rabbits with the view of ascertaining if Cerfontaine’s statements as to 
the migration of Trichina were well founded. Pieces of intestine with 
the mesentery were spread out under the Microscope and numerous 
sections examined. The author’s observations did not confirm those of 
Cerfontaine, who stated that the adult female Trichina migrated from 
the intestine to the mesenteric glands by way of the lymphatic vessels, 
and there brought her embryos into the world. Trichinae seem to 
prefer to stay in the lumina of the intestinal follicles, and hence are 
able to resist the action of purgative and anthelminthic remedies. The 
Trichina embryos are disseminated over the body, principally through 
the intermediation of the vascular system, and to a lesser degree by direct 
migration through the peritoneal sac and the circumjacent cellular tissue.
