Head of female ; 



b., buccal valve; p., papilla ; t., " trident." 



o*o6 mm. in male, 009-cri mm. in female; width (dorso- ventral), 0-075 mm. in male, 



o*i mm. in female. The length of the rods representing the tridents is about 0*06 mm. 



in the male, 0*07-0*1 mm. in the female. 

 ,.P' The posterior ring of the buccal appara- 



tus has a diameter of 0*033 mm. in the 

 male and 0*045 mm. in the female. The 

 oesophagus has the same structure as 

 in Camallanus, the anterior muscular 

 portion measuring (from the extremity 

 of the head) 0*38 mm. in length in the 

 male, 0*47-0*5 mm. in the female. The 

 distance from the head-end to the poste- 

 rior end of the glandular portion is o*8 

 mm. in the male, 1*02-1*08 mm. in the 

 female. The nerve-ring is situated at 

 0*15 mm. in the male, 0*19 mm. in the 

 female, from the anterior end ; the 

 excretory pore at 0*25 mm. (male), 0*31 

 mm. (female) ; and the minute, bristle- 

 like, cervical papillae at 0*28 mm. (male), 

 0*35 mm. (female). 



In the male, the caudal region has 



the general structure characteristic of Camallanus, with well-developed alae and caudal 



muscles. The tail is very short (a little over 0*06 mm.), sharply pointed, and usually 



curled ventrally, with its tip hidden by 



the alae. The caudal papillae are 



elongate and rib-like, diminishing in 



size towards the tip of the tail. As in 



Camallanus, there are seven pairs of 



preanal papillae, projecting into the 



alae. There are two large pairs curving 



inwards towards the ventral surface at 



the sides of the cloaca, and five more 



pairs of lateral postanal papillae. The 



three anterior pairs of these are rela- 

 tively large and close together. The 



spicules are markedly unequal in size 



and character. The right spicule is 



stout and provided with alae for the 



greater part of its length. It is about 



0*24 mm. long. Its tip is curled into 



a hook, but there is no barb. The left 



spicule is without alae, slender and
