-"XXV i First Report on Economic Zoology. 



Survey of Section (S) of Sub-group A. 

 ANIMALS CAUSING BODILY INJURY AND DISEASE TO RABBITS. 



I. By direct injury. 



Protozoa Coccidia produce disease in the liver (liver-rot). 



Porifera to Echinoderma. None. 



-Platyhelmia Numerous tapeworms in the intestines and cysts in the 



organs and tissues (Txnia i^cctinata, Cysticcrcus 



jnsciformis) . 



Nemertina None. 



Nematoda Strongylidx often cause great mortality (Strongylus 



strigosiis, Oxyuris ainbigua). 

 Chsetopoda and Crustacea None. 



Arachnida Psoroptcs produce scab and itch. 



Hexapoda Fleas {PuLcx gonioccplialus). 



Reptilia Various snakes. 



Birds Rapacious birds (hawks, falcons and crows). 



Mammals The fox, dogs, cats, weasels, stoats, etc. 



II. As germ carriers. 

 None known. 



Survey of Section (i) of Sub-group A. 

 ANIMALS CAUSING BODILY HARM AND DISEASE TO POULTRY. 



I. By direct injury. 



Protozoa Cause false coccidiosis of liver {Amceba meleagris), 



diphtheritic roup, epithelioma contagiosum. 

 Platyhelmia Tape worms often occur in all poultry {Davainea pro- 



glottina, Drcpanidoteenia infundihuliformis and others). 



Nemertina None. 



Nematoda Thread worms (Heicrakis) live in the intestines of fowls; 



the gape worm [Syngaimis trachealis, gapes). 



Chsetopoda None. 



Arachnida Sarcoptidx {Ae^lnvamg scabies, Sarcoptes i^uis), scaly leg 



{Sarcoptes miitans) ; ticks (Argas) ; mites (Dermanyssus 



avium) on skin and feathers. 

 Chilopoda and Diplopoda None. 

 Hexapoda Lice (Mallophaga), fleas (Pulicidx) and certain flies 



(Ornitliomyia) and sand flies (Sinmliiim) cause 



annoyance. 



MoUusca None. 



Reptilia Poisonous snakes attack poultry (chicken snake, Coluber 



quadrivittatus in N. America and others). 

 Birds Hawks (sparrov/-hawk) and crows take the chicks ; 



eagles, kites ; peregrine falcon. 

 Mammals Many mammals prey on poultry and eggs (fox, polecat, 



weasel, rat, Indian civet, leopard cat). 



II. As germ carriers. 



Chsetopoda Earthvrorms carry the ova and embryos of the gape 



worm and are eaten by fowls.
