RESEARCHES IN HELMINTHOLOGY AND PARASITOLOGY. 231 



In the intestine was another apparently undescribed Fluke-worm, 

 which may be named Distomurn pedocotyle. Of three individuals one 

 was 20 mm. long by 0.5 mm. thick ; the others were 40 to 45 mm. 

 long and 1.5 mm. thick. The body is cylindrical, narrowest at the 

 fore part and obtuse behind, with the ventral bothria larger than the 

 mouth and projecting in advance to an extent equal to the body ; 

 with the skin smooth and transparent, the yellow intestine and the 

 white and brown genitals shining through. 



The soft, yellow liver was throughout pervaded with a cestoid 

 worm, Anthocephalus c/oiigatus Rudolphi. The organ looked like a 

 bundle of tangled cotton cord packed in the hepatic substance. The 

 larger worms were probably upward of several feet in length, but 

 with much effort about a foot and a half of only one individual was 

 disengaged from the liver. In the larger specimens the cystic en- 

 velope of the cephalic end appears as a vesicle from a fourth to half 

 an inch in diameter. When disengaged, the cephalic extremity 

 appears as a sausage-shaped expansion, from three-fourths to an inch 

 long, within which was the inverted head and neck from half to 

 three-fourths of an inch long. The head, provided with a pair of 

 lateral oblique bothria, enclosed four thread-like proboscides armed 

 with numerous recurved hooks.

 NOTICES OF ENTOZOA. 



1. Ascaris hunbricoides, Linne. 



2. Trichocephaliis dispar, Rudolphi.

In the dissection of an Orang, Simla satyius, which died in our 

 Zoological Garden. Dr. H. C. Chapman found in the intestines sev- 

 eral worms (Proc. 1880, 166), which were submitted to my examin- 

 ation. Three seem in no respect to differ from the ordinary Ascaris 

 lumbricoidcs, one of the specimens being 18 centimeters long. One 

 from the coecum seems to be Trichocephalus dispar. The occurrence 

 of these parasites of man in a near relative outside the genus is an 

 interesting fact. 



Three other worms are unknown to me and I am in doubt as to 

 their generic character. They are females, and measure up to 26 

 centimeters long by 2.75 millimeters thick. They are more robust 

 than species of Filaria commonly are, and in this respect are more 

 like Eustrongylus gigas. Although neither of these usually live in 

 the intestine, I provisionally refer the worms to the former genus. 

 The body is nearly uniformly cylindrical, being 2.5 mm. thick, one
