The parasites referred to in this paper wei'8 collected from 

 mammals which died in the Gardens from October 1919 to 

 June 1921, during which period the writer held the position of 

 Honorary Parasitologist to the Society. 



In a previous Report, published in 1920 (1), I gave a list of 

 the parasites which were collected during the first eight months 

 of this period. Certain of these are again mentioned in this 

 paper, and to avoid confusion are marked in the Systematic List 

 with an asterisk (*). 



Leiperenia gcdebi, from the Indian Elephant [Elejihas indicus). 

 and Galoncus tridentatics, from the Clouded Leopard [Felis 

 nebulosa), have both been described as new species by Dr. M. 

 Khalil in previous papers in 1922 (2). The methods employed 

 in collection have been referred to in my Report of June 1920. 



The whole of the material has been worked out in the 

 Helminthological Department of the London School of Tropical 

 Medicine under the Directorship of Prof. R. T. Leiper, to whom 

 I am indebted for his kind assistance and many valuable 

 suggestions. 



In all, 43 species were collected from 36 hosts. Three of these 

 are apparently new to science and are described below. 



It is necessary to ci"eate three new Nematode genera : — 



(1) Troglostrongylus, for a new species of Metastrongylid worm 



found in the frontal sinus of a Leopard Cat {Felis 

 hengcdensis). Type T. troglostrongylus, gen. n., sp. n. 



(2) Gylicos'pirura, for the Spirurid from the stomach of the 



I'iger originally described as Hjnroptera subceqtialis by 

 Molin. Type C. subcequcdis (Molin, 1860), gen. n. 



(3) Pcqnllosetaria, for a new species of Filariid worm from the 



peritoneal cavity of Tragidus Stanley amis. Type P. tra- 

 gidi, gen. n., sp. n. 



In Tragidus stanleyanus a second new species also occurred ; 

 this I have named Setaria javensis, sp. n.
