 0.313mm broad. Rostelluni armed with a double row of altt^r- 

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

 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 pyrifarm, 127 (i by 20 /*; ova in egg cap- 

 sules same as in T. circumivallata; diameter of ova 22 /* by 

 16 It; oncosphere 9 ft. 



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 ha;rdly 

 be admitted as a species upon its present diagnosis.

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

 broad; rostellum convex or hemispherical, not prominent,

 overlapping. Genital pores irregularly alternate. Eggs ellip- 

 tical 75 ft to 85 ft; hooks or oncosphere 16 fi to 17 ft (Railliet) 18 

 u to 2Z ft (Dujardin). Development unknown.
