third of its length, the cirrus usually protruded for 0.1 or 

 0.2 inin., smooth, with slightly curved end. Cirrus pouch 

 thick and flnsk-sh;i]M'd, anterior; a half-dozen or more small 

 testes in anterior portion of link, sessile upon the vas 

 deferens. Vagina thick-walled, opening into a spheroidal 

 receptaculum seminis about midway between anterior and 

 posterior margins of link and external to testes; ovary rosette- 

 shaped and lying to median side of receptaculum; vitelline 

 gland posterior to receptacnluni. Uterine tube, with egg 

 sacs, extends along the posterior margin of link toward median 

 line, the tnk-s of the two sides not meeting. In ripe links the 

 uterine tubes fill nearly the entire link, the ova being held in 

 the reticulately distributed tubes and freed therefrom with 

 difficulty on tearing the segments, each l>eing held by some 

 surrounding adherent material. Ova (Fig. 10) colorless, 

 spheroidal, with a thin, pliant outer membrane, within which 

 is a granular and slightly laminated material separating the 

 outer membrane from the embryo. The latter has no distinct 

 membrane separating it from the surrounding granular 

 matter, is yellowish in hue, hexacanthous, coarsely granular, 

 and its outer surface rough with irregular elevations. Outer 

 wall of ovum measures 66 to 70 micromillimeters in length 

 by 56 to 60 micromillimeters transversely. 



Ascaris lepfoptera, Rudolphi (ex parte), new variety (Plate IV). 



The ascarides of the larger members of the cat family 

 have been the source of no little confusion from the first in 

 the endeavor to separate them from the common Ascaris 

 canis (Werner) of the cat and dog; and there is little con- 

 stancy of description of the ascarides derived from lions 

 alone, not to speak of the differences announced between 

 those of lions, tigers, and other of these larger cats. Rudolphi 

 (Eniozoa, II, i, p. 140) created a new species of the group 

 for an ascaris from a lion in the Zoological Gardens of Leipsic, 

 the verity of which has at one time been affirmed and again
