thoracico-abdominal cavity, and ' extending into the neck and 

 beneath the skin of the breast and abdomen. From the carcass, 

 Beventy-two worms were obtained, of which two-thirds were 

 females ranging from 90 to 120 mm. in length; the rest males, 

 ranging from 4n to 55 nun. From the abdomen of another bird, 

 Dr. Warren obtained five worms, three females from 55 to 90 

 mm., and i wo males, 40 and 55 mm. In twenty-two birds examined 

 b\ Dr. Warren, the parasites were found only in the two indicated. 

 Flic worms appear to be the Filaria obtusa Rudolphi, wdiich 

 infests the Hirundo rvstica, and other species of European Swal- 

 lows. The worms of the Snow Bird reach double the length of 

 those of the Swallows, but in other characters agree with the 

 descriptions of F. obtusa, as given by Diesing and Dujardin, and 

 also with the figures given by the latter (Hist. Helminthes, pi. 

 iii). except that it is uncertain as to the existence in our speci- 

 mens of the buccal armature represented b} r Dujardin. The 

 worms are translucent white, with a chocolate-brown intestine 

 and white uteri and testes. The caudal extremity is obtuse, 

 without appendages, and in the male possesses two spicules, of 

 which the longer curved one is F125 mm. long, and the shorter 

 twisted one 0*5 mm. long. The ova, containing developed 

 embryos, are 0*045 mm. long and 0032 mm. broad. 



Six other specimens, apparently also pertaining to Filaria 

 obtusa, Dr. Warren obtained from the abdominal cavity partly 

 imbedded in the wall, of a Meadow Lark, Sturnella magna. Two 

 are females, 130 and 140 mm. long by 0'625 mm. thick ; and four 

 are males, from 50 to 60 mm. long by 0\5 mm. thick. 



Six specimens of another Filaria were obtained from the 

 abdomen of a female Kingfisher, Geryle alcyoa. The species 

 appears to be the Filaria physalura of Bremser, described from 

 specimens obtained from several species of Brazilian Kingfishers. 

 Five of the worms are females, ranging from one foot to one foot 

 and a half in length, and from one to one and a half millimetres 

 in thickness. The head is obtuse, and the body gradualby tapers 

 to the tail. The mouth is bounded by a t pair of small conical 

 papillae. The five females measure, respectively, 12, 13, 14, 17, 

 and 18 inches. A single male is 35 mm. long by 0*625 mm. thick. 

 The tail is incurved, ends in a minute blunt cone, and is bialate, 

 with the alee short and quinquecostate. The length of the alated 

 portion is 0-35 mm. The spicule, partially exserted, is recurved. 

 The specimens, when alive, were pink in color, and exhibited a 

 slender chocolate-brown intestine, with large tortuous white uteri. 



From the thoracic cavity of a Gray Snipe, Gallinaqo Wilsoni, 

 Dr. Warren obtained five Flukes, 18 mm. long, by 4 mm. broad. 

 These appear to be Mono&tomum. mutabile. 



Prom a Whippoorwill, Antrostomus vociferus, Dr. Warren 

 obtained four worms, two females of 18 mm., and two males of 

 12 mm., which appear to be Ascaris subulata.
