in 1908 as a new species. He also discusses the variety tenellus, which 

 Grassi established within the species Bothriocephalus (or Dihothrio- 

 cephalus) latus. He describes his own observations on forms of this 

 species, and comes to the conclusion that D. parvus and D. latus var. 

 tenellus are just crippled forms of D. latus. 



Hydatid Cysts in Monkeys.* — William NicoU describes from the 

 abdominal cavity of Cynocephalus porcarius a hydatid with numerous 

 scolices attached to the wall of the cyst. It seems to be the hydatid 

 cyst that occurs in cattle, sheep, pigs, deer, and about forty hosts in all, 

 the adult occurring in Carnivores, particularly dogs. The author does 

 not name it. 



Trematodes of Australian Birds, f — S. J. Johnston describes no 

 fewer than twenty-one new species, belonging to nine families or sub- 

 families. In connexion with Scaphanocephalus ausiralis sp. n., it is 

 suggested that the " cone-shaped " body of Jagerskiold may assist to 

 form a cavity at the genital sinus, whereby self-fertilization may be 

 secured. Notably minute is the new species Levinseniella howensis, 

 specimens of which are less than a millimetre long. A new genus, 

 Austrobilharzia, is established, and is compared in detail with the other 

 genera of the family. Many interesting notes are communicated on the 

 new species ; a list of the previously described Australian Trematodes 

 is given ; the parasites are also classified under their avian hosts. 



Helminthological Notes from Switzerland. J — Emile Andre gives 

 a list of Trematodes, Acauthocephala, and other worm parasites which 

 he has observed for the most part near Geneva. The Trematodes 

 include Diplodiscus suhclavatus (Goeze) from Amphibians (and its 

 cercaria from the grass snake), Allocreadium isoporum (Looss) from 

 Gobio gobio, Gryptocotyle concavum Crepl. from the eider duck, 

 Plagiorchis mentulatus from Lacerta viridis, Strigea variegata (Crepl.) 

 from the bursa Fabricii of a crested grebe, and many more. The 

 Acauthocephala include Polymorphus minutus from the swan, Fom- 

 phorhynchus laevis from Silurus glanis, and some others. The 

 Cestodes include Ocenurus serialis from the rabbit, where it formed a 

 mass the size of a very large apple. The Nematodes noted are 

 Agamonematodum tritonis v. Linstow, in Triton alpestris, and Ancyra- 

 canthus denudatus v. Linstow from Phoxinus Isevis. 



Echinostoma ilocanum (Garrison). § — J. S. Hilario and L. D. 

 Wharton report the occurrence of this minute fluke in the intestine 

 of patients of the Manila Hospital, natives of Zambales. Garrison's 

 specimens came from Ilocos Sur. The fluke is a blood-sucking parasite, 

 and some anaemia is always associated with its presence. A description 

 is given of its structure and ova.
