PARASITES 



Tandon. — Strongylus meleagris gallopavonis, 



Buckingham. See Syngamus trachealis, von Siebold. — 

 Strongylus micrurus, Mehlis. Found in the arterial 

 aneurysms, trachea, and bronchi of domestic cattle. An 

 ovoviviparous species. The strongyle of horses and 

 asses was formerly included in this species, hut is now 

 referred to Strongylus arnfieldi by Cobbold and Rail- 

 liet. — Strongylus minusculus, Neumann. See 

 Strongylus tenuissimus, Mazzanti. — Strongylus 

 minutissimus, Megnin. This is shown by Railliet to 

 be but a form of Strongylus rufescens, q.v. — Strongy- 

 lus nodularis, Rudolphi. Syn., Ascaris mucronata, 

 Frohlich; Strongylus anseris, Zeder. This is found in 

 the esophagus, gizzard, and duodenum of the domestic 

 goose. — Strongylus ostertagi, Stiles (1892). See 

 Strongylus convolutus, Ostertag. — Strongylus ovi- 

 nus, Fabricius, Gmelin. See Strongylus contortus, 

 Rudolphi. — Strongylus ovis pulmonalis, Diesing, 

 Curtice. See Strongylus rufescens, Leuckart. — Stron- 

 gylus paradoxus, Mehlis (1830). Syn., Strongylus 

 elongatus (1845) ; Strongylus longevaginatus, Die- 

 sing (1851) ; Filaria trachealis, Bristowe and Rainey 

 (1855) ; Melastrongylus longevaginatus, Molin (1861). 

 Discovered at the end of the eighteenth century by 

 Ebel in the lung of a wild boar; afterward by Modeer 

 and Bremser, Rayer, Bellingham, Cobbold, etc., in 

 the bronchial tubes of domestic swine, and by Jort- 

 sits (or Jovitsits) in man, and by Koch in sheep. — 

 Strongylus pergracilis, the parasite of the Red 

 grouse (Lagopus scoticus) of Europe, causing so- 

 called grouse-disease. — Strongylus pulmonalis, 

 Ercolani, found in the bronchi and lungs of domestic 

 cattle. — Strongylus pusillus, S. Midler. This is 

 found in the bronchi of hares and wild rabbits, rarely 

 in the domestic rabbit, but very frequently in the cat ; 

 according to Railliet and Neumann all cases of pul- 

 monary helminthiasis in cats are due to this parasite, 

 which is present in one-fourth of all cats examined. — 

 Strongylus quadridentatus, von Siebold (1851). See 

 Dochmius duodenalis, Leuckart (1876). — Strongy- 

 lus radiatus, Rudolphi. See Uncinaria radiata, 

 Rudolphi. — Strongylus renalis, Moquin-Tandon 

 (i860). See Eustrongylus gigas, Diesing (1850). — 

 Strongylus retortseformis, Zeder, Rudolphi, Du- 

 jardin. This infests the small intestine of the hare 

 and wild rabbit. This name was incorrectly applied 

 by Bremser to Strongylus strigosus, Dujardin. — 

 Strongylus rubidus, Hassall and Stiles. An ex- 

 tremely small species found in the stomachs of pigs in 

 the United States. In some lots of hogs examined 

 the parasite was present in 75 per cent. — Strongylus 

 rufescens, Leuckart. Syn., Nematoideum ovis pul- 

 monale, Diesing; Pseudalius ovis pulmonalis, A. 

 Koch ; Strongylus ovis pulmonalis, Curtice. This is 

 found in the bronchi and pulmonary follicles of the 

 domestic sheep, goat and roebuck. The Strongylus 

 minutissimus, Megnin, which causes the verminous 

 bronchitis of African sheep, is but a variety of this 

 worm, as shown by Railliet. — Strongylus strigosus, 

 Dujardin. Syn., Strongylus retortaformis, Bremser. 

 This is very abundant in warren rabbits, giving rise to a 

 fatal anemia. — Strongylus sublatus, Cobbold Syn., 

 Hcematozoon sublatum, Gurlt. Found in the veins of 

 the dog. — Strongylus tenuis, Fberth. This is found 

 in the intestine and cecum of the domestic goose. — 

 Strongylus tenuissimus, Mazzanti (1891). Syn., 

 Strongylus minusculus, Neumann. Found in the mu- 

 cous membrane of the stomach of the horse. — Stron- 

 gylus tetracanthus, Diesing. See Sclerostoma tetra- 

 cantha, Diesing. — Strongylus trachealis, Nathusius. 

 See Syngamus trachealis, von Siebold. — Strongy- 

 lus trigonocephaly, Rudolphi. See Uncinaria 



trigonocephala (Rudolphi), Neumann. — StrongyUi 

 tubaeformis, Zeder. See Ankylostomum tuba 

 forme, Zeder. — Strongylus vasorum, Baillet. Tli 

 adult worm is found in the right ventricle of I 

 and in the lungs, the embryos in the pulmonar 

 arteries of the domestic dog. — Strongylus ventrico 

 sus, Rudolphi. This is found in the stomach an 

 small intestine of domestic cattle and Europei 

 deer. — Strongylus venulosus, Rudolphi. See i 

 cinaria radiata, Rudolphi. — Strongylus vitulorun 

 Rudolphi. See Ascaris vituli (Gmelin), Goeze.- 

 Strongylus vulpis, Zeder. See Uncinaria trigon 

 cephala, Rudolphi. — Stubenfliege. See 

 domestica, Linne. — Surra Parasite. See , 

 soma evansii, Balbiani. — Swiss Tapeworm. St 

 Bothriocephalic latus, Bremser. — Symbiotes (1857 

 A genus of psoric acaridans founded by Gerlac 

 (" Kratze und Raude, entomologisch und klinisc 

 bearbeitet, Berlin," 1857). Megnin's grounds fc 

 referring all members of this genus to the gem 

 optes, Gervais (1859), seem insufficient, as accord 

 ing to Scudder (Nomenciator zoSlogicus) the coleop 

 terous genus Symbiotes was not created by Redtenba Ik 

 until 1858 (Fauna austrica, " Die Kafer,' ' 2te Auflag; 

 Vienna, 1858, p. 371). We have therefore retaint 

 Gerlach's genus. — Symbiotes auricularum, ni 

 canis, var. cati, Neumann (1892). Syn.. 

 cynotis, tiering (1834) ; Sarcoptes auricularum, Lua 

 and Nicolet (1849); Symbiotes canis, Bendz (1862) 

 Symbiotes ecaudatus,ls\tgx\m (1876) ; Choriop, 

 datus, Megnin (1880); Psoroptes auricular is ca, 

 ell (1891). This is found in the ears of dogs and cat 

 producing that form of otacariasis accompanied t 

 epileptic symptoms, with which packs of huntingdoi 

 are often attacked. — Symbiotes avium, Caparin 

 (1880). See Epidermoptes bilobatus, Rivolta. — Sym 

 biotes canis, Bendz. See Symbiotes auriculart 

 var. canis, Neumann. — Symbiotes communis, Ve 

 heyen. Syn., Sarcoptes bovis (.<?), Hering ; . 

 bovis, Gerlach ; Symbiotes equi, Gerlach ; /J, 

 gus bovis, Fiirstenberg ; Dermatophagoidcs schertmti 

 ski, Bogdanow (1864) ; Symbiotes spathifer 

 nin (1876) ; Chorioptes spalhiferus , Megnin 

 Chorioptes symbiotes, var. bovis, R. Blanchanl 

 Chorioptes comtnunis , var. ovis, Verheyen ; Foot-. 

 This parasite lives in colonies, and without e 

 sub epidermic galleries causes a localized 

 especially on horses and cattle but also on 

 sheep, and rabbit, and is, according to U 

 and Ziim transmissible to man. — Symbiotes ecai; 

 datus, Megnin. See Symbiotes auricularum, 

 canis, var. cati, Neumann. — Symbiotes spathiferu' 

 Megnin. See Symbiotes communis, \ > 

 Symplectoptes cysticola, Railliet (1885

 cysticola, Vizioli (1870) ; Laminosioptes 

 Megnin (1880). An acaridan peculiar to the 6 

 nacea, living in the connective tissue of the abdH 

 viscera, peritoneum, muscles, and beneath the ski 

 fowls, pheasants, and turkeys, especially old 

 Synchytrium miescherianum, Rutin. Sed I 

 cystis miescheri, Ray Lankester. — Syngamus br 

 chialis, Miihleg (18S4). Found in the larynx, trac 

 and bronchi of geese by Pezibylka (185 j; 

 leg (1884). Thespecimens found in duck- 1>\ 11 

 and referred by him to Sclerostoma annatum, Di 

 may belong here. — Syngamus primitivus, M
