ZOOLOGY AND BOTANY, MICKOSCOPY, ETC. 369 



Intestinal Flagellates of Marine Fishes.* — A. Alexeieff describes 

 Urophagus intestinalis Moroff in Motella, and notes that it may require 

 a new genus (Trichomitus). He reports Trichomonas prow azeki Alexeieff 

 from Box salpa, Trichomastix motella sp. n. from Motella tricirrata, Tetra- 

 mitus mesnili (Wenyon) from Box salpa, Trgpanoplasma intestinalis Leger 

 in Boa (it also occurs in lumpsucker, conger, etc.). 



Spirochset from the Rabbit.f — C. Matins and M. Leger describe 

 from rabbits at Tonkin a species of Spirochait which seems to be new, 

 which they name S. raillieti. 



Parasites of Biliary Fever in Horses. $ — G. H. F. Nuttall and 

 C. Strickland find that there are two parasites in the blood of horses 

 suffering from " piroplasmosis," viz. Nuttallia equi (Laveran) and a true 

 Piroplasma (P. caballi Nuttall). 



Affinities of Spirochgets.§ — C. Clifford Dobell gives an account of 

 Cristispira veneris sp. n., and summarizes his view of the position of 

 Spirochaets. They may be conveniently collected as a distinct group 

 of Protists — Spirochsetoidea — which seems to stand alone. They have 

 no definite relations with Protozoa, Bacteria, or Cyanophyceae. The 

 group comprises three different sets of forms, which may be conveniently 

 classified in three different genera, Spirochseta, Treponema, and Cristispira. 



Spirochaets of the Mouth. |] — P. Gerber calls attention to the abun- 

 dant occurrence of various kinds of Spirochaets in the upper parts of the 

 respiratory and alimentary tracts, such as the mouth itself. He deals 

 with &. buccalis, S. dentium, S. vincenti, and other forms. The teeth, 

 the tonsils, and the tongue are the chief localities for Spirochgets in 

 tha buccal region ; they do not occur in other parts of the buccal mucus 

 membrane unless these are in a pathological state. 



Haematozoa of Australian Birds. IT — J. Burton Cleland and T. Harvey 

 Johnston report five apparently new species of Halteridium, a new Try- 

 panosoma, and various larval forms of Microfilaria. 



Coccidiosis in Sparrows and other Wild Birds.** — P. B. Hadley 

 calls attention to the common occurrence of the coccidium of " black- 

 head " (entero-hepatitis in the intestine of sparrows (Passer domesticus) 

 in America. The parasites were also found in the field-sparrow (Spizella 

 pusilla), white-throated sparrow (Zonotrichia albicollis), junco (Junco 

 hyemalis), hermit thrush, and robin (Merida migratoria). Severe cocci- 

 diosis was observed in the quail (Colinus virginianus) and in the grouse 

 (Bonaso umbellus). The appearance was like that seen in the cocci- 

 diosis of turkeys, fowls, pheasants, guinea-hens, ducks, geese, and pigeons. 

 The sparrow seems partly to blame for the diffusion of the coccidiosis, 

 which is now a severe menace to the poultry-raising industry in all parts 

 of the United States.
