 Trichosoma columba, Rudolphi ; Calodium tcnue, 

 Dujardin. Found in the large intestine of the 

 domestic dove ; it induces extreme anemia. — 

 Trichuris, Biitner (1761). See Trichocephalus hom- 

 inis, Schrank (1788). — Trinoton conspurcatum, 



Nitzsch, Denny, Piaget. Syn., Pediculus anseris, 

 Sultzer ; Trinotum conspurcatum, Burmeister. One 

 of the largest of the lice found on domestic animals, 

 common on the goose and swan, particularly the 

 latter. — Trinoton continuum, Piaget. Probably 

 only a variety of the preceding species. — Trinoton 

 lituratum, Nitzsch, Denny, Piaget. Syn., Ricinus 

 stirnce hirundinis, Linne ; Trinotum lituratum, Bur- 

 meister ; Trinoto7i squalidum, Denny ; Trinotum squal- 

 idum, Verrill. Found with other species on geese 

 (Dendrocygna arborea, Anser albifrons, Anas clyp-

 Found on the domestic duck. — Trinoton squali- 

 dum, Denny. See Trinoton lituratum, Nitzsch. — 

 Trinotum conspurcatum, Burmeister. See Trinoton 

 conspurcatum, Nitzsch. — Trinotum squalidum, Ver- 

 rill. See Trinoton lituratum, Nitzsch, Denny, Piaget. 

 — Trombidium americanum. The true American 

 harvest-mite, with eight legs, sometimes confounded 

 with the hexapod stage of a species of Tetranychus, 

 under the name of Leptus irritans. — Trombidium 

 autumnalis. See Tetranychus autumnalis , Shaw. — 

 Trombidium cinereum. The hexapod larva of this 

 or some closely allied species is reported as a pseudo- 

 parasite of man. — Trombidium holosericum, Fabri- 

 cius. According to Megnin it is the larval hexapod 

 of this species which has long been designated as 

 Rouget, Red Flea, Harvest-bug, Leptus autumnalis, 

 etc. This is a mistake, as this hexapod is the larva 

 of Tetranychus autumnalis, Shaw, q. v. — Tropido- 

 cerca fissispina, Diesing (1855), von Linstow (1879). 

 Syn., Tetrameres sp., Leuckart (i860). A nematode 

 found in the mucous membrane of the proventriculus 

 of the duck (Anas boschas domesticus). — Tropidocerca 

 inflata, Diesing (1861). Syn., Spiroptera inflata, 

 Mehlis, Creplin ; Tetrameres lurmochrous, Creplin 

 (1846); Tropidocerca paradoxa, Diesing (partim) 

 185 1 ). Found in the proventriculus of the domestic 

 duck. — Tropidocerca paradoxa, Diesing (1851). 

 Syn., Tropisurus paradoxus, Diesing; Spiroptera 

 inflata, Mehlis, Creplin (1846); Tetrameres Juemocrous, 

 Creplin (1846). Found in the proventriculus of sev- 

 eral birds, among them the domestic duck. The 

 worm discovered by Simonds, and named Simondsia 

 paradoxa by Cobbold (1864), is referred to this species 

 by some writers, but it seems improbable that this is 

 warranted, as the worm was found in a hog, whereas the 

 entire genus of Tropidocerca seems to be parasitic only 

 in birds. — Trout-leech. See Hirudo troctina, John- 

 son. — Trypanosoma evansi, Balbiani. $>yn.,Spiro- 

 chate evansi, Steel ; Trichomonas evansi, Crookshank ; 

 Hcematomonas evansi, Osier ; Surra Parasite. The 

 cause of the very serious epizo5tic pernicious anemia 

 in horses, mules, and camels, called Surra, prevailing 

 in India and Southern Asia. Rankin recommends 

 large doses of quinin frequently in milk, with iron 

 and arsenic, at the commencement of the disease. — 

 Trypanosoma lewisi, Danilewsky (Saville Kent). 

 Syn., Herpetomonas lewisi, Saville Kent. A pale, trans- 

 lucent, motile, flagellate hematozoon found by Lewis in 

 the blood of the rat. Kent suggests, on the grounds 

 of the particular position of the flagellum, that further 

 investigation may demonstrate this to be one of the 

 spermatic elements of minute nematodes, microfili 

 or other endoparasitic forms. Danilewsky calls alt<n 

 tion to the similarity between this form and that 

 described by him in the blood of birds. — Trypsoderma 

 cuniculi, Wiedemann (1830). See Cuterebra cioiic- 

 uli, Clark (1815). — Tse-tse, Tse-tsefliege, Ger. j 

 Tse-tsevlieg, 1 hitch. See Glossina morsitans, W 

 wood (it closely resembles Stomoxis calcitra 

 abundant in Central Africa. — Tunga. See Sar-
