It is larger, had not the lateral cuticular spikes near the head, and the 
genital spicules in the male are of extraordinary length. The genital 
opening of the female is near the tail and is not surmounted by a pro¬ 
jection as in Strongylus contortus. 
The female, 21 mm. in length, greatest breadth .5 mm. The mouth is 
terminal and the cuticle surrounding it is thickened so as to form a circle of 
small rounded projections. The oesophagus, 1.9 mm. in length, is thick 
muscular and ends in a slight dilation before the marked junction with the 
intestine. The rectum is thin walled and terminates in the anus close 
to the sharp pointed tail. 
The ovarian tubes are double, are not twisted round the intestine as in 
Strongylus Contortus, and end in a long thin walled vagina in which a 
single row of eggs is contained. The genital opening is marked by no pro¬ 
tecting fold and is situated .5 to .6 mm. from the tip of the tail. 
The male, 19 mm. long .44 mm. broad, terminates in a bilobed caudal 
pouch strengthened by ribs. The spicules which are protruded between 
the lobes for a variable length are continued in the interior, are distinctly 
tubular and terminate in a trumpet-shaped expansion. They are equal, and 
the total length is 6.2 mm. or more than \ the length of the body. 
In both males and females the anterior part of the body for some 
1 to 1.5 mm. is contracted and the cuticle somewhat thinner than elsewhere. 
To this part debris is adherent, as is usual in portions of worms such as 
Tricocephali which are plunged into the mucous membranes. 
I can find no record of Strongylus corresponding to this worm, proba¬ 
bly it is a new species. So many members of this genus are dangerous 
that this worm should be regarded with grave suspicion. 
The Anguillula was not present in large numbers. Only females were 
found. They measured 5.5 to 6 mm. in length and .03 mm. breadth, and are 
probably a new species, Anguillula Bovis. 
The most important parasite of domesticated birds found was Heterakis 
Maculosa which is found in enormous numbers in the intestine of certain 
groups of pigeons in Kwala Lumpur. Treatment by powdered areca nut is 
highly successful. The mortality amongst such groups of birds untreated 
is great. 
In monkeys various species of worms were found. In no instance did 
they belong to any of the species infecting man. They included species 
belonging to the Sclerostoma, Oesophagostoma, Ascarides, Oxyurides and 
Tricocephali. None of them appear to be of pathological importance. 
FlLARIDiE. 
In man the only filaria found were the embryos of Filaria Bancrofti 
(Filaria hosminis sanguinis nocturna). The blood of 100 patients (Chinese 
75, Tamils 23, Malay 2) taken between 10 p.m. and midnight showed Filarial 
Rmbryos in 3. Of these 2 were Tamils and one Chinese. 
Elephantiasis is observed from time to time but very rarely in this 
district. Dr. McClosky informs me that the cases of elephantiasis, 
admitted at the District Hospital in the last 4 years is only 3, though the 
total admissions for all causes amount to 17,804 in that period. 
One Eurasian born in this country who had lived for some years in 
Madras had recurrent attacks of lymphangitis, slightly enlarged groin glands, 
and filaria nocturna were found in his blood. As his father died some
