cuticle (fig. 44) is finely striate longitudinally, the striations being 

 interrupted at short intervals by annular spaces free of striations, 

 these spaces being especially distinct in the posterior portion of the 

 body. 



. Male 17.1 to 21 mm. long. Body thickest in the middle, 30 to 52 /* 

 thick, the head end 10 to 16 fx thick and the tail end 20 to 33 fi thick. 

 Anterior esophageal portion of body 4.8 to 7.2 mm. long. The cells 

 of the esophageal cell chain are about eight times as long as wide. 

 The bent, unciniform spicule (fig. 45) is 1.2 to 1.4 mm. long. It is 

 6 fx thick at the proximal end and terminates in a fine point distally.

The sheath is smooth and transversely striated and may be evaginated 

 to a distance of 0.9 mm. The posterior extremity of the body ter- 

 minates in two distinct lobes of greater diameter than the preceding 

 portion of the body.

Host. — Ejnmys norvegicus {Mus decumanus). 



Location. — Urinaiy bladder. 



Locality. — Germany. 



It is quite possible that this species and the foregoing, Capillaria 

 papulosa., are identical, since they are both trichosomes and found in 

 the urinary bhadder of closely related species of rats, which are cos- 

 mopolitan animals, and in areas so comparatively close to one an- 

 other as Germany and Italy. However, since one species is based 

 on the male and the other on the female, it is perhaps better to keep 

 the species distinct for the present and merely call attention to the 

 likelihood of their being identical. C. schmidti might be G. annulosa.
