266 DR. M. KlJy\LlL ON THE NEMATODE 



Ova. — The ova, as seen in tlie vagina, are tliin-shelled. TJiey 

 are 60 /.i in length and 35 /x, in breadth. Tlie contents are in the 

 morula stage of development. 



Habitat. Intestine of African elephnnt (Uganda). 



Discussion. 



This genus is in some respects allied to Pteridopharynx. The 

 presence, however, of the cuticular collar round the anterior end 

 of the body, and the peculiarity of having a branched externo- 

 dorsal ray in the bursa, clearly differentiate the members of the 

 Sfenus Memphisia. 



The two species here described are easily sorted out, even with 

 a hand lens. The very marked and projecting cuticular collar 

 of M. memphisia, together with the spike-like female tail, suffice 

 to differentiate them. The spicules in M. aziza are shorter; 

 the distance between the anus and vulva is longer than in 

 M. memp)hisia. In addition, the total length and the diameter 

 of the various structures of the body and the position of 

 the cervical papillae and excretory pore are different in both 

 species. 



No member of this genus has been recorded from the Indian 

 elephant. 



Genus Amira Lane, 1914 (amended). 



Fairly small worms with thick cuticle. Cuticular bosses may 

 be found anterior to the male bursa. The mouth is terminal, 

 and is surrounded by an external and an internal leaf-crown. 

 There are six head papillae, none of which are prominent. 

 The mouth capsule is very short; the oesophagus is hour-glass 

 in shape, the nerve collar siirrounding the constriction. There 

 is a large oesophageal funnel. The oesophagus has a cuticular 

 lining. 



The male : The dorsal lobe of the bursa may or may not 

 be enormously elongated. The pre-bursal papillae are very much 

 elongated. The two equal spicules are of enormous length and 

 very fine. There is an accessory piece. 



The female : The vulva lies close cephalad of the anus. The 

 long vagina runs cephalad, and divides into two parallel ceplialad- 

 running uteri provided with ovejectors. The colourless thin- 

 shelled ova are segmented.

Source of Material. — The material consists of one male and five 

 females, which were sent to Prof. Leiper by Lieut.-Ool. Clayton 

 Lane. They ai^e the co-types of Amira omra.
