slow wriggling. Oral movements were distinct ; there were four papillae round the 
mouth. The tail ot the larger tapered and was pointed ; of the smaller, tapered 
slightly, was truncated, and a thin skin extended like a loose bag or hood from the 
head end. 
M anson also gives meagre descriptions of haematozoal embryos in Gracupica 
nigricollis and Goura coronata (Malay Archipelago). 
Stossich 1 describes in his monograph 212 species of Filariae — we have 
arranged a complete list of these from his work, giving their hosts, and sites, and 
also the literature referring to each. This list will be found in the Bibliography.
