Diagnosis; Strobila ur to lU3i"m long. Head very small 

 0.313mm broad. Rostellum armed with a double row of altoi- 

 nately larger and smaller hooks, the larger 8 /i, the smaller 

 5 fi long, in form very similar to those of T. circumvallata; 

 suckers very small, 98 fi in diameter, armed with 6-8 concen- 

 tric rows of hooks, the latter varying in size, but of similar 

 form. Neck 2.5'nni long, thin. Young segments 0.323nim broad 

 by 0.2mm long; middle segments trapezoid, 3mm broad; poster- 

 ior segments 2mm long; middle segments trapezoid, 3mm broad, 

 posterior segments 2mm broad by 1mm long. Genital pores ir- 

 regularly alternate; genital apparatus (very sufficiently de- 

 scribed); cirrus pouch pyriform, 127 /i by 20 /*: ova in egg cap- 

 sules same as in T. circumvallata; diameter of ova 22 /t by 

 16 /i; oncosphere 9 fi. 



Host: Migratory quail (Cotumix coturnix.) 



"Whether Blanchard is correct in his opinion can be deter- 

 mined only by a comparison of specimens, but in the mean- 

 time one is bound to admit that T. pluripunctata can hardly 

 be admitted as a species upon its present diagnosis.

Diagnosis: Length, 9mm to 45mm (according to Molin), lOOnim 

 to 130mm (according to others). Head gloibulai, 0.5mm to 0.55mm 

 broad; rostellum convex or hemispherical, not prominent. 

 0.28mm to 0.32mm broad, armed with about 20S hooks T /i to 8.8 

 C long, arranged in two rows; these hooks have a very short 

 dorsal and a long ventral root; suckers 10 /i to 11 /t not prom- 

 inent. Neck very short (Duj.) neck absent (Railliet). Anter- 

 ior segments 3-5 times as broad as long, being broader than the 

 head, but very short; the following segments increasing grad- 

 ually in size and becoming nearly as long as broad, borders 

 overlapping. Genital pores irregularly alternate. Eggs ellip- 

 tical 75 fi to 85 fi; hooks or oncosphere 16 ft to 17 /i (Railliet) IS 

 u to 23 /I (Dujardin). Development unknown. 



Hosts: Chickens. 



Geographical distribution: France (by Dtijardin); Italy (by 

 Molin, Grassi, Rovelli); Denmark (by Krabbe): Turkestan (by
