and 



what laterally situated, as are also two pairs at about the level of 

 tlie cloaca, the rest being subventral. The number and 

 arrangement of the papillae are precisely as 

 in 5'. otolicni (van Beneden), thougli in 

 other respects the species are very distinct. 

 The tail of the female is 0.65—0.8 mni. 

 long. The vnlva. which was not observed 

 by Ratzel. lies rather in front of the 

 middle of the body (at abont 8.2 mm. 

 from the posterior end in a specimen 

 14 mm. long). The short muscular ovi- 

 jector runs forward at first from the 

 vnlva, but bends sharply back upon 

 itself, ending in an oval chamber like 

 that described by Seurat, in certain allied 

 species, as the glandular portion of the 



"sphincter." The eggs are roundish-oval in shape 

 measure from 0.065 x 0.052 mm. to 0.085 x 0.067 mm. 



SUBULURA Sp. 



A species of Svbnhirn, represented by females only, was 

 taken from Rattns sahaniis at Mt. Dulit, together with 

 Protospirura muris. Of the three specimens only one is com- 

 plete. This measure? some 25 mm. in length. The buccal 

 cavity has the lining thickened in its anterior portion, and 

 there are three large, irregularly-shaped teeth at the base. 

 The tail is 1.3-1.5 mm. long, and tapers to a very slender 

 termination. The eggs measure about 0.072—0.08 mm. x 

 0.058 mm. The species would probablv be assigned to 

 AUorlapa by those authorities who consider that there are 

 sufficient grounds for the separation of AUodapa, as a genus, 

 from Suhidura. It appears impossible to refer the material 

 definitely to any of the species of Suhuhira or Allodapa record- 

 ed from rodents, though in measurements it closely resembles 

 S. pigmentata, Gedoelst, 1917, which occurs in Sciurus pre- 

 vnsti in Sumatra.
