MR. E,. J. ORTLEPP ON THE 



are five pairs of sessile papillse, of which the first two pairs are 

 small and inserted in a line just behind the anus ; the 3rd pair 

 is found at the level of the last part of pedunculated papillae, the 

 4th }iair in the middle of the tail, and the last just anteiior to 

 the front limit of the posterior third of the tail. 



The spicules are of equal length, but the base of the right is 

 very slightly thicker than that of the left. They are 455 jj, long, 

 the right being 29 ju broad at its base and tapering gradually to 

 a fine point, the left being 32 ^ thick as its base and having its 

 posterior end widened out to form a spear-head 1 60 ,u long by 

 95 ^ broad.

Fhysalojptera honnei, sp. ii. 

 A = Caudal extremity of male. B = Spicules. 



This species has many characters in common with Ph. ohticsis- 

 sima, as shown by the general shape, ornamentation and arrange- 

 ment of the papillae of the male bursa, the nature and size of the 

 teeth, and the general shape of the spicules. It is, however, 

 distinguished from it by its longer cesophagus, slightly more 

 posterior position of the vulva, the presence of a cushion-like 

 swelling anterior to the vulva, the absence of a trunk portion 

 behind the egg-chamber, and in that the spear-head of the left 

 spicule is better set off. 



I have named this species after Dr. Bonne, of Surinam, who 

 collected and presented this material to Professor Leiper.
