(il. FUaria lHbi<ito-i><ii>ill(ina, Alessandrin! (Path. Mus., 17), 

 \\as collected hy Dr. J.J. Uepp, in Iowa, from the peritoneum 

 of a cow, Bo.f liniriix. A single example (Path. Hist., 1675) 

 was sent into the laboratory from the Zoological Gardens 

 labelled as having been found in the body of a bison, Bison 

 (iiinricaniiJi (P. /. G. Lab., 9(X)); but when further data were 

 sought in reference to its precise habitat, there was found no 

 reference to its discovery in the records of the laboratory of 

 the Gardens, and a question existed in the mind of the patho- 

 logist as to the correctness of the label. There is therefore 

 an uncertainty as to this specimen, which, however, if cor- 

 rectly labelled, is, as far as the writer knows, the first instance 

 of its occurrence in the American bison. 



<ii>. FUaria gracilix, Rudolph! (Path. Hist., 1642, 1645), 

 has been identified from specimens found in the peritoneal 

 cavity of two monkeys in the Zoological Gardens, the first 

 a white-throated cebus, Cebus hypoleucus (P. Z. G. Lab., 955), 

 the second from an unindicated species. 



63. FUaria pungent, A. Schneider (Path. Hist., 1696, 1716), 

 is recorded as found in the air sacs of a red-headed weaver- 

 bird, Tandia madagascariensis (P. Z. G. Lab., 1028), and 

 from the peritoneum of a blue-bearded jay, Cyanocorax 

 cyanopogon (P. Z. G. Lab., 404). 



64. FUaria australis, Linstow (Path. Hist., 1701). was 

 met in the peritoneal cavity of a brush-tailed wallaby, Petro- 

 gale pencillata, from the Zoological Gardens. The writer 

 regards the specimen described as FUaria spelcea, Leidy 

 (Pr. Acad. Nat. Sci., Phila., 1875, vol. 27, p. 17), as probably 

 identical, in which case Leidy's name would take preference 

 to that of Linstow's. 



65. Spiroptera incerta, n. s. (Path. Hist., 1109, 1120, 1453, 

 1463, 1613, 1616, 1618, 1619, 1620, 1621, 1622, 1623, 1624, 

 1625, 1626, 1627, 1628, 1629, 1630, 1631, 1644, 1661, 1672, 

 1675, 1686), has been met in the proventricle and gizzard of 

 several dozen birds. The parasite has been endemic in the 

 bird house at the Zoological Gardens, and has appeared par- 

 ticularly among the parrakeets, amazons, conures, and parrots;
