 37 cm. long and 10 mm. in extreme diameter, while the third, a 

 male picked up near the horse-market in Parkville, Victoria, was 

 i'T nil. 'ong and 8 mm. in diameter. The female opening in all

No. 9.— Ascaris kimbricoides, L., 1 ToS. 



This common parasite of man is repi'esented in this collection 

 by 18 worms, chiefly female, sent from the Children's Hospital. 

 The specimens are noi-mal in character, excei)t tliat some apparently 

 immature are below the usual size. The males vary from 10 to 

 14 cm. in length, and 3 to 5 mm. in diameter ; the females from 

 131- to 30 cm. in length and 4 to G mm. in diiimeter. Tlie 

 teeth and sense papillae on the oral lips are not at all easily 

 seen, though they can be detected in a few cases. The female 

 opening is situated typically at one-third the body length from 

 the anterior end. The tail of the male tends to coil ventrally in 

 a vertical plane. The two spicula are equal in length and 

 similar in shape. 



Host. — Child : no details of habitat are given, but presum- 

 ably the worms were found, as usual, in the small intestine. 



Locality. — Melbourne, 1897, per Dr. OtKcer.
