 Jynacophorus crassus, Sonsino. — Gynaecophorus 

 crassus, Sonsino. Syn., Bilharzia bovis, Sonsino ; 

 Bilhar-Ja crassa, Sonsino. This was found in 1 876 

 it Zagazig, Egypt, in the portal vein, ureters and 

 urinary bladder of domestic sheep and cattle. It has 

 since been found in Italy. Neumann regards it as 

 but a variety of Gynacophorus hamatobius, Diesing, 

 and hence dangerous to man. It gives rise to symptoms 

 similar to those caused by the last-named parasite. — 

 Gynaecophorus haematobius, Diesing (1858) ; Syn., 

 Sckistoma hamatobium, Weinland (1858) ; .Oistoma 

 use, Harley (1864) ; Distoma haematobium, Bilharz, 

 (1852), Kiichenmeister, Moulinie, Leuckart ; Theco- 

 1 haematobium, Moquin-Tandon (i860) ; Bilharzia 

 magna, Cobbold ; Bilharzia hamalobia, Cobbold 

 (1858). A fluke originally found by Bilharz in 1851 

 in Egypt in 63 per cent, of fellahs and copts. It has 

 since been frequently found in the natives and Euro- 

 pean residents along the entire coast of East Africa, 

 in Arabia. Mauritius. India, and Brazil, producing a 

 grave disorder known as endemic hematuria. It also 

 occurs in an African monkey, the Mangabey (Cercopi- 

 thicus fuliginostts, Geoffroy). It is most abundant in 

 the vessels of the portal system, and mesentery, and in 

 the hemorrhoidal and vesical veins. It feeds upon the 

 d; no intermediate host is known, and it is sup- 



I posed to be introduced into the human system by im- 

 pure drinking-water, as a swimming embryo. Eouquet 

 of Cairo reports favorably on the use of extract of male 

 fern, and Dight, of Beirut, recommends the injection of 



I large amounts of sulphuretted hydrogen and carbon 

 dioxid into the rectum and bladder. — Gyropus gra-

 . Danilewsky. — Haematobia stimulans, Mei- 

 gen. A group of flies recorded by Neumann as 

 troublesome to man, and cattle in pastures. The saw- 

 hematobia (Hamatobia serrata, Davaine) is particu- 

 larly spoken of as bloodthirsty, and common in Europe 

 and America. The parasitescollect in swarms at the base 

 of the horns, or on the abdomen, back, flanks or upper 

 parts of the legs. The eggs are deposited in the fresh 

 dung, and they may be destroyed by throwing lime over 

 thedung lying in pasture?. — Haematomonas evansi.
