that the portion of turtle's flesh given him for comparison, and sup- 

 posed to be part of Danilewsky's original material, contained no Mi- 

 crosporidia, but was full of minute air bubbles between the muscle- 

 fibres. It seems hardly possible, however, that Danilewsky and L. 

 Pfeiffer could have mistaken these air bubbles for parasites, yet neither 

 Railliet, Balbiani or the reviewer could find any Microsporidia. The 

 material came from L. Pfeiffer.— C. W. Stiles. 



Trematodes.— Hassall (American Veterinary Review, July 1891) 

 describes the large liver-fluke found in American cattle as Fastiola 

 carnosa; as this name is preoccupied he changes the name (Am. Vet. 

 Rew. Sept.) to F. americana. [As yet it is impossible to say much in 

 regard to this species. The animal is undoubtedly specifically different 

 from D. hepaticum, but as I have stated in my Animal Report for 1891; 

 bears very great resemblance to Bas-i'~ ZHstomum 1 1 ignum. Dr. Has- 

 sall and I are at present at work upon this species and hope soon to

Cestodes.— Dr. V. A. Moore recently presented a case of Eckino- 

 coccus hydatid in a pig, before the Biological Society of Washington, 

 D. C., and in the discussion which followed, Stiles spoke of two more 

 unpublished cases in animals and one in man. Van Cott, of Brooklyn, 

 has recently given a full account of this last case. It is high time, 

 that the Health authorities in the various cities insist upon burning 

 every organ infected with this hydatid, found in the slaughter-houses, 

 and that more care is used in importing dogs (the final host of this tape 

 worm,) from infected regions, if we wish to avoid an experience such as 

 Australia has had for the past quarter of a century. 



Prof. Linton has recently published several valuable papers on the 

 parasites of fish (Notes on the Entozoa of Marine Fishes of New Eng- 

 land, I and II ; a contribution to the Life History of Dibothrium cor- 

 diceps ; on two species of larval Dibothria from the Yellowstone Park ; 

 all published by the U. S. Fish Commission and free to scientists). 

 These papers will be found to be very valuable in determining the 

 parasites of fish, as the descriptions are very complete. In reading 

 the diagnoses, however, one should remember that Linton unintention- 

 ally misused the word "lateral." In places where that word occurs. 

 "dorsal" or "ventral" should be inserted. That Linton simply wrote 

 lateral, by mistake, is proven by the fact that he speaks of the breadth
