35) states, that he found T. infumlibuliCorniis in large numbers 

 in the epidemics of syngamosis among pheasants, but it is evi- 

 dent that the fornx he referred to was his T. agama. Bremsci 

 also records it from pheasants, but his observation should be 

 confined. Megnin recoixls it for pigeons and in Goura, but 

 those observations also need confirmation, for Megnin remarks 

 that the specimen from Goura had three rows of hooks upon 

 the suckers, ( ? Davainea cesticillus, q. v. p. 48). Piana (1882, 

 p. 392) found this parasite the most common tapeworm of 

 chickens. Grassi& Rovelli (1889, p. 404; 1892, pp. 33-34, 89) state 

 that they found the larval stage in the house fly (Musca domes- 

 tica), but they did not prove their point experimentally. Crety 

 (1890, pp. 5-8) records Coturnix communis as a new host, and 

 'remarks upon the anatomy of the parasite. Unfortunately the 

 figures are unsatisfactory, and the description is, therefore, 

 not of such value as it otherwise would be; from his descrip- 

 tion the following characters are taken: 



Diagnosis: (T. infundibuliformis) Strobila to 100mm. Head 

 very small, spheroidal, 0.387mm broad; rostellum armed with 

 20 hooks upon its cupola-like extremity; length of rostellum 

 0.137mm, breath %2 /j, to 75 /«; hooks 23 fi long; suckers 0.215mm 

 by 0.156mm. Neck very short, 0.313mm in length; middle seg- 

 ments 0.4Smm long, posterior segments 0.901mm long. Genital 



pores . Male genitalia: Testicles 16 to 20 in number, 29 



IM to 44 /i in diameter, situated in median field; vas deferens 

 begins about the middle of the segment, firsit portion slightly 

 sinuous, lateral portion very tortuous; cirrus pouch glo'bose, 71 

 fi in diameter; cirrus armed with numerous small spines. Fe- 

 male genitalia: Receptaculum seminis 106 fi by 39 /i, situated 

 near the ovary; ovary globose, near anterior margin, occa- 

 sionally irregularly divided into two halves; oviduct runs from 

 ovary, in median line, di.S'tally; vitellogene gland in about the 

 proglottid is globose, occasionally irregularly divided into two 

 portions, vitello-duct runs cephalad from its median portion; 

 shell gland very small, between ovary and vitellogene gland; 

 uterus forms very quickly, in the mature proglottid it oc- 

 cupies the entire median field and is composed of a large cav- 

 ity imperfectly divided into numerous small cells ( — egg cap- 

 sules?). Ova 55 n by 46 /x, with 3 shells; oncosphere 33 /*> 

 hooks 17 iJ, Krabbe: hnoks 12 /" to 17 fi.)
