sac, though provided with a stout musculature, is not very con- 

 spicuous. The cirrus has no spiny armature. The vitelline glands 

 are, as in P. lactuca, distributed on either side of the testes. The 

 position and structure of the ovary, shell-gland, and the other 

 female generative organs is the same as in P. lactuca. 



Phyllobothrium blakei, Shipley & Hornell. 

 (Plate I, fig. 5.) 



Thirteen specimens from the intestine of Trygon kuhli trawled 

 from Periya Paar. 



Shipley and Hornell described this species in 1906 from about 

 half a dozen specimens (half the number of which were without 

 heads) from the intestine of Trygon kuhli. 



The head, which we figure, bears four frilled sessile bothridia 

 without accessory suckers. There is no neck. The proglottides 

 do not show any overlapping at the posterior margins. The last 

 segment is about three times as long as broad. 



The disposition and arrangement of the reproductive organs 

 is the same as in the other species of the genus. The secondary 

 uterus is comparatively large for the size of the proglottid, and the 

 cirrus-sac is well developed ; the cirrus, however, is not echinate. 



Phyllobothrium compacta, sp. nov. 

 (Plate I, figs. 6, 7.) 



In our collections we found five specimens of a Phyllobothrium 

 which cannot be assigned to any of the previously described spe- 

 cies. We have named it P. compacta in view of the compact 

 appearance of the head. The specimens were obtained from the 

 intestine of Trygon kuhli trawled from Anaivilundun Paar, Ceylon 

 (4 — 5 fathoms deep) on the 19th February, 1911. 



The largest specimen measures 51 mm. but the others do not 

 exceed 40 mm. The greatest width is 4 mm., and this point lies 

 about the middle of the worm ; the proglottides decrease in width 

 posteriorly. The head has a very compact appearance owing to 

 the sessile nature of the large and well-developed bothridia. The 

 edges of the bothridia are slightly crumpled and there are no ac- 

 cessory suckers. 



The specimens unfortunately are not fully mature but the 

 anatomy as far it can be made out resembles that of P. lactuca. 



The species may be characterised as : — Length about 51 mm., 

 greatest breadth 4 mm., graduall}^ decreasing to a little more than 

 2 mm. posteriorly. Head with four compact and sessile bothridia, 

 without accessory suckers ; neck long. There is only a slight 

 overlapping of the proglottides. Reproductive pores lateral on 

 alternate sides.
