Fig. 2. Profile view of the lower end of the body of another Strongylus falcifer, exposing the bursal 

 lobes of one side and the projecting spicules. ( x 27 diam.) 



Fig. 3. Lower end of the body of a female Strongylus falcifer, showing the mode of termination of the 

 reproductive and digestive organs, and more especially the characteristic form of the tail. 

 ( x 23 diam.) 



Fig. 4. Half-profile view of the head and neck of a female Dochmius Sangeri, showing the mouth, buccal 

 cup, oesophagus, and upper end of the chylous intestine. ( x 33 diam.) 



Fig. 5. Lower end of the body of a male Dochmius Sangeri, seen from behind. It shows the expanded 

 hood and entire system of rays, as well as the spicules in their retracted position. ( x 33 diam.) 



Fig. 6. Profile representation of the lower end of the body of a female Dochmius Sangeri, showing the 

 anal cleft and finely pointed tail. ( x 33 diam.) 



Fig. 7. Upper part of the body of a female Filaria Smithii, exposing the head, a double row of auriculate 

 folds, papilla?, oesophagus, and commencement of the chylous intestine. ( x 30 diam.) 



Fig. 8. Front view of the lower end of the body of a male Filaria Smithii, displaying the spicules, the 

 anal opening, and the relation of the latter to the stalked papilla?. ( x 30 diam.) 



Fig. 9. Profile view of the tail of another male Filaria Smithii, in which the papilla? are not seen. 

 ( x 30 diam.) 



Fig. 10. Another side view of the lower end of the body of a male Filaria Smithii. The tail is more 

 curved, the spiciiles being completely retracted, the papilla? of the left side being also seen 

 throughout their whole extent. (Flattened by pressure, and x 50 diam.) 



Fig. 11. Front aspect of an Amphistoma papillatum, giving a general view of the internal organs as seen 

 through the transparent integuments. It also shows the oral sucker, reproductive papilla, 

 circular folds or ruga? of the body, and especially the disposition of the fungiform papilla? 

 within the concavity of the caudal sucker. ( x 18 diam.) 



Fig. 12, This illustration represents a Fasciola Jacksoni, viewed from behind, and with the aid of 

 transmitted light. It explains the position of the oral and ventral suckers, reproductive papilla, 

 exserted cirrhus, two or three of the uterine coils, their contained ova, and also, more par- 

 ticularly, the mode of branching and distribution of the digestive tubes. ( x 10 diam.)
