50 SPOLIA ZKVIiAMCA. 



andeveloped, and only thoprimordiumof the testis and the genital 

 sinus is recognizable. The central portion is separated from the 

 peripheral by a dorsal and ventral broad band of transverse muscles. 

 The calcareous bodies are closely packed and exceptionally 

 numerous. 



Since the reproductive elements are undeveloped the hooks on 

 the rostellum demand especial attention as specific characters. 



There are two rows of 19 hooks, measuring in length 0238 mm. or 

 0*158 mm. These are straight with the short handle obliquely 

 placed to the main axis ; in the large hooks it is about in the 

 middle, in the small hooks a little behind the middle and unsplit. 



Amongst the cestodes living in allied carnivores the species 

 belonging to ihe genera Mesocesioides and DipijUdium may be left 

 out of account ; Tcbiiia oligarthra, Diesing, like Tcenia echino- 

 cocciis v., Sieb, consists of but 3-4 small proglottides. T(Bnia 

 laticolUs, Rud., has only one row of hooks. There remain for 

 comparison Tcenia no t'eZZa, Neumann ; Tcenia serrata, Goeze ; and 

 Tcenia crassicoUis, Rudolphi. 



l^cenia, novella, Neumann, has two rows of 20-21 hooks, which 

 measure 0"25-0'26 mm. and 0" 150-0' 155 mm. The handle has its 

 end directed towards the hook-end, and in the smaller hooks the 

 root is much shorter than the hook-end and bent backward. The 

 handle is split. 



Tcenia serrata, Goeze, has two rows of 17-24 hooks. The large 

 ones measure 0-225-0*250 mm., the smaller 0"120-0"160 mm. 

 The handle arises far in front of the middle in the large forms, 

 but behind the middle in the small forms where it is split. 



Tcenia crassicoUis, Rud., has two rows of 13-26 hooks, which 

 measure 0-38-0-42 and 025-0"27 mm. respectively. The handle is 

 stout and directed towards the point. It is situated behind the 

 middle in the small hooks. Whilst these hooks are much larger 

 than those of the new species they are much smaller than those of 

 Tcenia ccenurus, Rud. 



Habitat : The intestine of Felis pardus. The stomach of this 

 leopard contained monkey's hair. The host was shot between 

 Wirawila and Tissa, in the Southern Province of Coylon.

 PL I., figs. .5 to 7. 



This tapeworm measured 18'2 mm. in length, 0'12 mm. breadth 

 anteriorly and 099 mm. posteriorly. The maximum breadth is 

 that of the proglottides a little behind the middle, where they are 

 1*42 mm.broad and 0-12 mm. long. All the proglottides are very 

 short. The genital pores are on the edge and are unilateral.
