shell measuring about 0*07 X 0*04 mm., and usually showing a slight internal thickening 

 at one pole. One end of the shell, as seen in uiero, is occasionally drawn out almost 

 to a point. The content of the egg is unsegmented at the time of laying. 



The characters of this form are such that it appears to form a link between the genera Heterakis 

 and Aspidodera. It has cephalic " cordons " similar to, but rather less highly-developed than, those of 

 Aspidodera ; while it possesses long, pedunculate caudal papillae in the male, like those of Heterakis in 

 shape and arrangement, and unlike the more sessile papillae of Aspidodera. The markedly dissimilar 

 spicules and the absence of an accessory piece are also characters of Heterakis rather than of Aspido- 

 dera. 



Two species of Heterakis have been recorded in peafowl — H. papulosa (Bloch) and H- hamulus, v. 

 Linst., 1906. The former is, of course, a well-known species and the genotype of Heterakis. Although 

 the description of H. hamulus is rather brief, it appears sufficient to prevent the identification of the 

 present form with that species. 



Subfamily SUBULURINAE, Travassos, 1914. 



Genus Subulura, Molin, i860. 



Subulura sarasinorum (Meyer, 1896). 



This species occurred in the intestine of a slender loris (Loris gracilis) l in the 

 Calcutta Zoological Garden.

Subulura galloperdicis, sp. nov. 

 (Fig. 38.) 



This species was collected from the intestine of the Red spur-fowl (Oalloperdix 

 spadicea). 



The female measures 11*5 to 12*5 mm. in length and about 0*4 mm. in thickness; 

 the male 9-5 to 10 mm. and 0-3 mm. respectively. The head is small, measuring 

 about o - o8 mm. in diameter. There are narrow cephalic alae which extend to a dis- 

 tance of about 1 mm. from the anterior end. The buccal cavity is 006 mm. deep, 

 about 0*023 mm. wide at the anterior end, and 0*031 mm. at the posterior end. 

 There are three triangular teeth at the base of the buccal cavity, two sub-dorsal, and 

 one ventral and median. The height of the teeth is about 0*013 mm. The nerve- 

 ring is situated at 0*27 mm. from the head, whilst the excretory pore opens on the 

 ventral surface at 0*45 mm. from the head. The oesophagus consists of a long mus- 

 cular portion with the usual prebulbar swelling, and a large bulb containing the grind- 

 ing apparatus. The anterior portion is 1*5 mm. in length, and the prebulbar swelling 

 0*14 mm. in thickness. The bulb is roughly spherical and has a diameter of 0*2 mm. 

 The vulva is situated in the anterior half of the body, dividing the latter in the ratio 

 of 3 : 4. There is a short transverse vagina from which large, well-developed ovejec- 

 tors run anteriorly and posteriorly. The ovaries commence at the anterior and pos- 

 terior bends of the uteri, and terminate in the vicinity of the vulva. The bend of 

 the anterior genital tube is at about 0*42 mm. from the oesophageal bulb, while that 

 of the posterior is at about 0*22 mm. from the tip of the tail. The ova measure
