Found also on many occ;»sions in previous yeare encai>suled on tlie viscera. A conuiion form is 

 identical with that from the s<iueteague (fig. 107); length of one, lO.o nun. Another common form 

 is larger ( IS mm. to 28 mm. ). In the larger siK'cimens the i-hanu-teristic head of Asrniix may lie made 

 out through the iiive.sting niemlirane. The posterior end in this form is bluntly rounded with a sharp 

 mucronate tip. A small specimen, !l mm. in length, differed fniiii the loregoiiig hy having the postanal 

 region rouglieneil as shown in fig. 120, from Shiiiihiiiiiii'.

 ends abruptly in a short ami compariUively narrow rectum, with a top-shaiH'il anal glauil on the left 

 side anil another on the dorsal side, both near the termination of the intestine proper (fig. 104). 

 Dimensions of one in millimeters: I.^-ngtli, 20; diameter of head 0.14, 2 mm. hack of head 0.34 

 maximum 0.34, 2 nun. from |>osterior end 0.24, at anal aperturt! O.IB; distance of anal a|>ertHre from

 meter from posterior end, O.o; length of embryos from 0.2 to 0.3(); greatest diameter of embryos 

 0.014. The color of" the alcoholic specimen is yellowish white, with tlie intestine showing as a 

 relatively broa<l, dark-brown stripe. The intestinal walls have an abundant ileposit of pigment and 

 are traversed by transparent anastomo,<ing lines, which produce an effect which re.^i'uibles the veiuxtion 

 of a leaf. The emljryos, which an' in myriails, ajijiear to have escajied into the body cavity by rupture 

 of the nterus. They are blunt at one end and exceedingly slender, even tlagellale, at the other.
