92 SPOLIA ZEYLAXTCA. 



intestine is often prolona:ed into a coecnm, which lies below the 

 cesophaijiTS, and the latter frequently carries a tubular gland which 

 rests upon the dorsal side of the intestine. The male possesses 

 two equal spicula or cirri, but no bursa at the caudal end of the 

 body. 



Aficaria has the musculature characteristic of Schneider's Poly- 

 myaria, and belongs to the division Secernentes, in which the 

 lateral fields or ridges are narrow and project well inwards : each 

 ridge contains a canal, and the two lateral canals unite in front 

 in the mid-ventral line, where they open to the exterior by a 

 common pants excretorius, not far behind the mouth. 



1. — Ancaris rot,undwaudaia^ n.sp. 

 PI. I., fig. 1. 



Habitat : stomach and intestine of Calotes ophiomachus (" ka- 

 tussa," Sinh.), Colombo. 



Cuticula annulate or transversely striate ; lips broad and short, 

 denticulate, without intermediate lips, papillae set far back ; dorsal 

 lips nearly quadrilateral with rounded fore-edge, 0*22 mm. 

 broad and 0-068 mm. long. 



The oesophagus occupies ^j^ of the entire body length in the 

 male, ^\ in the female. 



The male has a length of 46 mm. with a diameter of 0*7H mm. 

 The tail is rounded with a conical extremity and equals ^-^ of 

 the body length. The cirri or spicula measure 8*8 mm. ; at the 

 tail end of the body on each side there are papillae — thirty-one prae- 

 anal papillae and three post-anal. The prae-anal papillas extend 

 forwards to a distance of 8-2 mm. from the caudal extremity. 

 Quite at the posterior end there is also a dorsal papilla. 



In the female, with a length of 72 mm. and diameter 1*14 mm., 

 the rounded tail occupies , ^r, of the body length, and terminates 

 in a fine conical prolongation. The vagina opens approximately 

 in the middle of the body. The thick-shelled eggs are nearly 

 spherical, O-OTS mm. in diameter ; the shell surface is finely 

 granulatpd. 



2. — Asatris ceylanica, n.sp. 

 PI. I., fig:. 2. 

 Habitat: {a) intestine of' the Brahminy kite, HaliaMur indus, 

 Bodd.. Colombo ; (b) stomach of the fish eagUs Poliaetufi 

 ichthyaefus, Horsf., Kalpitiya. 



This is a fairly large species, allied to A. rnicrolaMnni, but not 

 identical with it. All the specimens are fragmentary, so that 

 measurements cannot be given.
