"306 SUMMARY OF CURRENT RESEARCHES RELATING TO 



New Nematodes.* — 0. v. Linstow describes Heterakis cordata sp. n., 

 from the gut of Lkillipepla squamata, from Mexico ; H. paradoxa sp. n., 

 from the gut of Diddphys dorsigera L. ; Gloacina octodactyJa sp. n., from 

 the bronchi of Canis familiar is ; Proleptus tortus sp. n., from the gut of 

 Cistudo ornata Ag. A note is added on the lip characters of Ascaris 

 obtusocaudata Rud., and on the dimensions of its ova. 



Intestinal Worms of African Pigmies.f — A. Looss had an 

 opportunity of examining the faeces of a pigmy people in central Africa. 

 He found the eggs of five Nematodes, viz. Ankylostomum, Ascaris, Tri- 

 chocephalus, Schistosomum Jmmatobium, and Oxyuris vermicidaris. The 

 Anlcylostomum belonged to the species Naca.tra americanus, which is dis- 

 tributed over the southern states of North America, South America, 

 and Brazil, amongst whites and natives. 



Shell of Ascaris ovum.J — L. Jammes and A. Martin find, as a result 

 of experiment with the eggs of Ascaris vitidorum, that the shell is more 

 readily permeable l>y gases than by substances in solution. Tlie serai- 

 permeability of the shell is neither perfect for all substances, nor does 

 this property continue indefinitely for a given substance. 



Filaria of Agama colonorum.§ — J. Rodhain makes a note of the 

 presence of filaria embryos in the peripheral blood of Ayama colonoruyn 

 in the Congo Free State. Of twelve animals examined, four were found 

 •to be infected. 



Case of Trichinosis with living Trichina. ||—Y. Babes describes a 

 -Ciise of trichinosis in a twenty-one year old subject in Roumania, in which 

 the trichinae were alive. The case is of interest, as trichinosis has l)een 

 absent from Roumania for more than twenty years, and as a later infec- 

 tion in this instance is to be regarded as out of the question. The 

 •diseased conditions, which were numerous, and affected heart, kidneys, 

 liver, etc., were doubtless the result of a pathological metabolism of 

 many years, whose products acted on these organs with toxic effect. 



Platyhelminthes. 



New Phyllobothridse.lF — Bruno Klaptocz describes from Notidanus 

 {Hexanchus) yriseus two Phyllobothridte, viz. Monorygma rotuiidum 

 sp. n. and Crossobothrium cantpaimlatum sp. n. He gives a detailed 

 .account of the ripe proglottis of the latter and a key to Phyllobothrid 

 genera. 



Cestodes of Birds.** — "W. Clerc gives an account of the Cestode 

 parasites of the birds of Oural, dealing with the genera HynienoJepis, 

 Trichncephaloidis, Ddepis, Choanotcciiia, etc. 0. Fuhrmann discusses 

 the general characters of the genus Hymenolepis and its distribution
