PAEASITES OF ELEPHANTS, 219 



The female tail is slightly bent dorsally. It narrows gradually 

 to its tip, whicli is slightly rounded. There is apparently no 

 papillse on the female tail. The length of the tail is 0-36 mm.

Embryos. — The female is viviparous. The embryos are so 

 closely packed that it was impossible to arrive at an approximate 

 estimate of their length. 



Habitat. Coats of the stomach of the IndLin. elephant (India). 



Discussioii. 



Baylis described fully P. indicum and P. africana. He was 

 not able to find material containing P. smithii, which has onlv 

 been alluded to once since it was described by Cobbold. There 

 has been some doubt as to the identity of P. indicum and 

 P. smithii, as Cobbold's description was not full. For this 

 reason the latter species is described here in full. It is certainly 

 a different species from P. indicum. although found in the 

 same host. It is a much smaller worm, and the measm-ements 

 of its various organs are likewise shorter than the corresponding 

 figures of P. indicum. 



The shape of the auricular appendages is different from that 

 alluded to above. The African species is of very great length, and 

 its auricular- appendages of the cuticular thickening of the head are 

 quite distinctive. All its other dimensions are correspondingly 

 longer than in the other species. 



MlCSOFILAPoIA. 



Evans and Rennie record the presence of a microfilaria in blood 

 taken from an elephant during the daytime. It measured 180 /i 

 in length and Q fj. in breadth. It is possible that it was really 

 a microfilaria, but I suggest that it is more probable that the
