from its fellow. The third lobe of the bursa is deeply notched in the middle line, thus 

 imparting to the hood a spuriously four-lobed figure. The spicules are short, rather 

 broad at the base, and pointed at the tip or lower end. When the tail of the male 

 is viewed either from the front or from behind, the spicules display the not un- 

 common V-shaped outline. 



The tail of the female worm presents well-marked characters (PL XXIV. fig. 0). In 

 addition to those mentioned in the diagnosis of the species, the uniform and rather 

 sudden narrowing of the body in this region, together with the presence of a con- 

 spicuous and somewhat gaping anal cleft, would render the future recognition of this 

 species a very easy matter, even if no male were procurable. In some specimens the 

 neck in either sex is much more contracted than in the particular example which I have 

 figured. 



7. Filaria Smituii, sp. nov. (Plate XXIV. figs. 7-10.) 



Body smooth, with very fine transverse stria?, filiform, and of equal thickness through- 

 out. Head furnished with two rows of translucent auriculate appendages, supporting a 

 few minute papilla?. Mouth simple, surrounded by four small papilla? and numerous 

 slight elevations exterior to the papilla?. (Esophagus of great length, without bulb or 

 constrictions. Tail of the male short, bluntly pointed, with winged appendages sup- 

 ported by eight stalked papilla?, four on either side. Spicules long, slender, unequal. 

 Tail of the female short, bluntly pointed, usually directed backwards. Anus sub- 

 terminal at the base of the tail. 



Length of the male J of an inch. 

 Length of the female ^ of an inch. 



Hab. Coats of the stomach of Elepltas indicus. 



The delicate little worms thus named cannot be confounded with the larger species of 

 nematode already stated to occupy tumours in the walls of the stomach of the Elephant. 

 Apart from the relative disparity of the worms themselves, the parasitic growths or 

 abodes containing them are of much smaller size. The tumours enclosing the Filarice 

 barely exceed the size of an ordinary filbert nut, presenting also an oval flattened figure. 

 As in the larger formations, however, each tumour displays a single round aperture com- 

 municating with the cavity of the stomach. The interior structure of the growths does not 

 depart in any marked degree from the alveolar or multilocular character of the abodes of 

 Strongylus foliatus ; but a relatively far greater number of worms were found to occupy 

 the "abodes" of this species. I have named the species after the veterinary surgeon 

 through whose instrumentality I had an opportunity of making the " find." Well 

 enlarged, and seen in profile, the head shows sculpturings which together form a double 

 festooned border, whilst within the concavity of each ear-shaped fold of integument 

 there are minute papilla?. In the neighbourhood of the mouth there are also other 

 prominences, as well as special papillary elevations which probably serve as taste- 

 organs (PL XXIV. fig. 7). 



In consequence of their larger size, the females are easily recognized. The actual 

 position of the reproductive outlet evaded my observation ; but the diagonal direction
