1084 MR. R. J. ORTLEPP ON THE 



cuticular tubercles. (Arrangement of the papillse as in Ph. alata.) 



Thi-ee pre-a.nal sessile papillas arranged in a triangle. Four pairs 



of post-anal ventral papillae ; the 1st and 2nd pairs of these are 



slightly stalked, and are found on the posterior lip of the cloaca ; 



the last pair is situated just behind the middle of the tail. Five 



pairs of lateral stalked papillse grouped about the cloaca, the last 



inserted at the level of the 3rd pair of post-anal ventral papillse. 



Right spicule robust and large, 550 /a long ; left spicule slenderer, 



feebly chitinised, and longer. 



Female 33 mm. longx 1 "055 mm. thick. Tail long, conical, and 



pointed. Caudal pores in its anterior third. CEsophagus 5-61 mm. 



long. Vulva in front of termination of cesophagus, 3"8 mm. from 



anterior end. Unpaired female genitalia very long ; vagina 



2"15 mm, long and directed backwards ; egg-chamber 3'125 mm. 



long ; trunk 500 yw, long, and divides posteriorly to give rise to 



two uteri. Receptacula seminis pyriform, 600 X 325 /j,. Egg 



elliptical, thick-shelled, and embryonated ; they measure 50 x 25 jx. 



Hosts: Aquila chriisaetos.\ /-rr i -n o a i

(38) Physaloptera subalata Schneider, 1866. 



Length of male 32 mm. 



Tips of lips very prominent. Outer tooth longer than inner 

 tooth ; edges of smaller teeth quite parallel, and pointed at the 

 tip. Four pairs of stalked circumcloacal papillse. Three sessile 

 pre-anal papillse, the middle one nearer the anus ; three pairs 

 behind the anus, of which the last two pairs are close together, 

 one pair behind the other, and the last pair nearer the mid-line ; 

 the other pair is situated at about the junction of the 1st and 2nd 

 tail thirds. 



Host : Falco sp. Stomach. Brazil. 



With regard to the nature of the teeth, Schneider's description 

 differs from his figure ; he states that the outer tooth is larger 

 than the inner, and in his figui-e shows the outer tooth very much 

 smaller. I take his figure to represent the correct nature of the 

 teeth. 



Seurat (1914 c) tentatively referred to this species some Phj'sa- 

 loptera which he obtained from the stomach of a Buzzard, San 

 Martino, Corsica. Briefly he describes this material as follows : — 

 Large and robust body. Two lips, each with a small and cuneiform 

 outer tooth and a large tripartite inner tooth. OEsophagus 

 1/4" 5 in male, l/6th in female of body-length. Vulva in anterior 

 third of body, 3 mm. behind oesophagus. Vagina 1 mm., egg- 

 chamber 750 yu, long ; trunk divides to give origin to two uteri. 



Bursa with four stalked circumcloacal papillse. Three pre-anal 

 ventral papillse form a triangle ; two pairs immediately behind 

 anus, 3rd pair in middle of tail. 



Spicules unequal ; left 840 /x long, slender, and pointed ; right 

 less than 400 /x long, and thicker.
