ABT^IS PARASITIC NEMATODES FROM CHINA SCHWARTZ 5 



Genus SETARIA Viborg, 1795 



SETARIA EQUINA (Abildgaard. 1789) 



Specimens from the small intestine of a mule {Equus mulus) col- 

 lected in Peking in 1922 (Cat. No. 26428, U.S.N.M.). This parsite 

 normally occurs in the peritoneal cavity, but has also been reported 

 from other parts of the body including the intestine. The occurrence 

 of this parasite in the intestine should, however, be viewed with 

 suspicion owing to the possibility of accidental transfer in the course 

 of necropsy. 



SETARIA LABIATQ.PAPILLOSA (Alessandrini. 1838 or Perroncito. 1882) 



A single female from the "honeycomb" (reticulum) of Bos taurus, 

 collected in Peking in 1921 (Cat. No. 26414, U.S.N.M.). So far as 

 the writer is aware this is the first record of the occurrence of this 

 parasite in the digestive tract. In view of the possibility of acci- 

 dental transfer at necropsy this unusual location of the parasite is 

 open to suspicion. 



Superfamily SPIRUROIDEA Railliet and Henry, 1915 

 Family PHYSALOPTERIDAE Leiper, 1908 



Genus PHYSALOPTERA Rudolphi, 1819 



PHYSALOPTERA. species Qarvae) 



In addition to two presumably undescribed species of Physaloptera 

 which are being studied by Dr. A. E. Chapin of this bureau, several 

 larval Physaloptera from the liver of a badger, Meles leptorhynclius, 

 collected in Peking in 1921, were examined by the present writer 

 (Cat. No. 26413, U.S.N.M.). These larvae are about 8 mm. long 

 by 414ju wide. The esophagus is 2 mm. long by 162/i in maximum 

 width. The distance from the anterior extremity to the cervical 

 papillae is 540^1, the nerve ring being half way between these points. 

 The excretory pore is posterior to the cervical papillae. The tail is 

 270m long. 



Family SPIRURIDAE Oerley, 1885 



Genus SPIROCERCA Railliet and Henry, 1911 



SPIROCEKCA SANGUINOLENTA (Rudolphi, 1819) 



Adults specimens of this species were collected in 1921 from a 

 "boil of the stomach" of a fox {Cards vulpes) in Mongolia (Cat. No. 

 26409, U.S.N.M.). Larval forms of this species from the mesentery 

 of Erinaceus dealhatus were collected in Peking in 1922 (Cat. Nos. 

 26437, 26438, and 26441, U.S.N.M.). These larvae agree in all 

 respects with Seurat's description of the larvae of S. sanguinolenta.
