256 Mr. R. Daubney on Two Species of 



XXVIII. — A Note on Two Species of the Genus Miirsliidia 

 (^Nematode J Strongyloidea) parasitic in the Wart-Hog. By 

 R. Daubney, M.Sc, M.E.C.V.S., Ministry of Agriculture 

 and Fisheries. 



The material dealt with in this paper is the property of the 

 British Museum (Natural History), South Kensington. I 

 wish to express my thanks to l)r. H. A. Baylis for his 

 generosity in placing this material at my disposal. The 

 type-specimens of the new species are in the British Museum 

 (Natural History). 



Genus MuiiSHiDiA, Lane, 1914. 



This genus, described by Lane (1914), differs from tlie 

 genus CyliGostomum in characters of the head, the male bursa, 

 the spicules, and the female tail. Lane's diagnosis has 

 recently been reprinted in Khalil (1922, p. 220). 



That both of the species discussed below should be assigned 

 to this genus is indubitable, although hitherto its members 

 have been described from elephants only. It is, however, 

 always of peculiar interest to note the occurrence o£ members 

 of a helminth genus, previously associated entirely with ohe 

 host genus or group, in another host-group whose relationship 

 to the first is not very obvious. 



Murshidia pugnicaudata (Leiper, 1909). 



Sjnonym. Cylichnostomum pugnicaicdatum, Leiper, 1909. 



This species has been collected recently on four occasions 

 from the wart-hog [PhacocJioerus cetliiopicus) in Zululand. On 

 each occasion there was also present a closely allied species — 

 Murshidia hamata, — which is described below. From the 

 description of Leiper (1909, p. 23) there is reason to suppose 

 that the material from which his species was originally 

 described included also the second species. His figure of the 

 oesophagus in particular would appear to apply more closely 

 to M. hamata than to M. pugnicaudata. However, it is 

 clearly indicated by his figure of the spicules which of the 

 two species should be regarded as M, pugnicaudata, 



Murshidia hamata, sp. n. 



Host. W ^Yt-hog (P/iacochwrus cethiojncus). 



Locality. Zululand. 



This is a fairly long robust form. The females measure
