35) states that he found T. Infundlbullformls In large numbers 

 in the epidemics of syngamosls among pheasants, but It Is evi- 

 dent that the form he referred to was his T. agama. Bremsei 

 also records it from pheasants, but his observation should be 

 confined. Megnln records 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, ( ? Davalnea cesticlllus, q. v. p. 48). Plana (1882, 

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

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

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

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

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

 ■re-marks 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:

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

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

 0.137mm, breath 62 /i to 15 ft; hooks 23 fi long; suckers 0.215mm 

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

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

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

 b<:'gln« about the middle of the segment, first portion slightly 

 sinuous, lateral portion very tortuous; cirrus pouch globose, 71 

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

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

 near the ovary; ovary globose, n^ar anterior margin, occa-

 ovary. In median line, distally; vltellogene gland in about the 

 proglottid Is globose, occasionally Irregiilarly divided Into two 

 portions, vltello-duct runs cephalad from Its median portion; 

 shell gland very small, between ovary and vltellogene gland; 

 uterus forms very quickly. In the mature proglottid it oc- 

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

 sules?). Ova 5.-J /I by 46 ft. with 3 shells; oncosphere 33 /i,
