In the domesticated animals Mr. Ford, the Government Veterinary 
Surgeon, has observed A scans Marginata in the dog, and A scans Suilla in 
the pig, and Oxyuvis Cuvvula in the horse. 
In horses Strongylus Armatus was found both in the sexual condition in 
the caecum and in the agamous form in intestinal tumours. It is probably 
injurious in those positions but more so in other situations. 
In a bullock and a calf Strongylus contortus was found in large numbers 
but appears to be a rare parasite. 
In dogs Tricocephalus depressiusculus, Uncinaria trigonocephala are found, 
and in the Oesophagus or in tumours in its vicinity the Spiroptera sanguinolenta 
is not uncommon. 
Strongylus micvurus so common in the lungs of cattle in the West 
Indies and Central Africa has not been observed here. 
In Indian buffalo calves but not in adults a Syngamus was found in the 
upper part of the larynx. The worms were firmly attached to the mucous 
membrane. The mouth has the usual strongyloid armature opening into a 
buccal expanded cavity. The opening of the oesophagus is guarded by 6 
teeth. The oesophagus itself is very muscular and .9 mm. in length. The 
genital opening of the female is situated about the junction of the anterior 
with the second quarter of the body. The worms were red in colour and 
the male firmly attached in each instance to the female. The head of the 
male was free. In size and characters this parasite closely resembles 
Syngamus trachealis of domesticated birds. The length of females was 
i 6 to 8 mm. and of the male 3.5 to 5 mm. 
In one calf in addition to Strongylus contortus an Anguillula nearly twice 
the length of the human Anguillula intestinalis was found, and in addition a 
second Strongylus in small numbers in the abomasum. 
The Strongylus Contortus is readily recognised even with the naked 
eye by the way in which the ovaries are twisted round the alimentary 
canal. 
The head is unarmed and terminal. Two lateral cuticular spikes 
pointing backwards are situated .4 mm. from the head. The oesophagus is 
1.5 mm. in length, a powerful muscular tube slightly dilated just above the 
junction with the intestine. The anus is subterminal and the tail is sharply 
pointed. There are two ovarian tubes. The vagina opening is in a deep 
sulcus surmounted by a fold of the cuticle and subjacent tissues at a point 
I about one-fifth of the length of the body from the tip of the tail. The females 
; were 18 to 20 mm. in length. 
The males 9 to 10 mm. in length have a bilobed caudal pouch, each 
lobe strengthened by 4 ribs. 
The two equal spicules including the trumpet shaped expansion are 
only .35 mm. in length. 
The position of the vulva is that described in Strongylus Contortus, 
and not as in the more usual bovine species Strongylus Convolutus. The 
worms also are larger than that species. Strongylus contortus is a danger¬ 
ous worm to sheep, the allied species in the goat and cattle are also 
dangerous. No other cause of death was found in the calf from which this 
and the two other species of worms were obtained. It had rinderpest about 
a month before but made a good recovery. The other Strongylus, which I 
propose to call Strongylus Fordii, was not present in such large numbers.
