developed, but much emaciated, with oedema of the limbs. Lapa- 

 ratomy showed a large tumor in the region of the ovary. On 

 January 18 the stool was sent in for routine examination. A few 

 ova of Echinostoma ilocanum were found. Male fern treat- 

 ment was given, but for reasons already set forth, the specimen 

 of stool collected was not examined for the worm. 



Case U. — (Case 6920) C. V., male, 10 years old, born and 

 residing in San Narciso, Zambales, admitted to the Philippine 

 General Hospital complaining of yaws. He is fairly well devel- 

 oped and well nourished, but somewhat pale. Blood picture 

 shows 75 per cent htemoglobin ; otherwise it is normal. On De- 

 cember 7 examination of the stool showed a few eggs of Echi- 

 nostoTna ilocanum. No treatment for worm was given, because 

 the patient left the hospital the day after the examination. A 

 large number of eggg of Ascaris and occasional eggs of hookworm 

 and Trichuris were found. 



Case 5. — We could not secure authority to publish the clinical 

 record of this case. 



THE ANATOMY 



Historical. — Echinostoma ilocanum was first discovered by 

 Philip E. Garrison in Ilocano prisoners in Bilibid Prison, Ma- 

 nila, in 1908. He found the eggs in 5 cases and on treating his 

 last case with male fern recovered 21 worms from the stools. 

 He described the worms as a new genus and species, giving 

 them the name Fascioletta ilocana. Later he sent 4 specimens 

 to Doctor Odhner, at Upsala, and in a paper in the Zoologischer 

 Anzeiger, in 1911, Doctor Odhner pointed out several new fea- 

 tures of the anatomy and showed that the worms belong to the 

 old genus Echinostoma whose type species is Echinostoma echi- 

 natum (Zeider 1903) found in domestic ducks and geese. Since 

 that time there are no reports of the finding of this worm, 

 although Willets reports finding . similar eggs in one case in 

 Cagayan. 



Another species, Echinostoma malayanum, was reported in 

 1912 by Leiper from natives of Singapore and the Federated 

 Malay States. 



Dimensions. — In fifteen specimens measured Garrison found a 

 maximum length of 6 millimeters and a maximum 'breadth of 1 

 millimeter and a minimum of 4 millimeters by 0.75 millimeter. 

 We have found a somewhat greater range in the size of our speci- 

 mens. The dimensions of eight worms, the first three collected 

 on November 2 and the others on January 22, were as follows :
