ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 661 



Piroplasma of Dog.*— B. Galli-Valerio has found in dogs, chiefly in 

 hunting dogs, an endoglobular Haemosporidian, Piroplasma cairis, which 

 produces a sickness characterised by high fever, icterus, and haemo- 

 globinuria. It is peculiar in being pathogenic for dogs only. It 

 increases in the blood by division and sporulation, and it is probable it 

 has a sexual cycle in the body of a tick, which serves as intermediate 

 host. When seen free in the plasma, the parasite exhibited appearances 

 resembling the flagella of the haemosporidian of human and bird 

 malaria. The sickness has been observed in Italy, France and Africa, 

 and probably exists in other countries. 



Myxosporidia of Flat-fish.f— H. M. Woodcock reviews the recorded 

 instances of these sporozoa in the flat-fishes in the light of several 

 recently discovered cases which he describes. There appears to have 

 been some doubt as to the identity of the species occurring. The writer 

 concludes that there are only three forms known to infest these fishes — 

 viz. Glugea stephanl, in gut-wall of flounder, plaice, and Pseudophuro- 

 iiectes americanm ; Sphwroxpora platessce, sp.n. in otic capsule of plaice ; 

 and a species of Pleistophora in the liver of Rhombus triacanthus.
