NO. IO COCKROACHES—ROTH AND WILLIS IOI 
(Sanders, 1929). Australia, Indo-China, Guam, Rabaul, Reunion 
(Fielding, 1928). British West Indies (Hutson, 1938, 1943). For- 
mosa (Kobayashi, 1927). Samoa (Alicata in Schwabe, 1951). The 
geographical distribution of O. mansoni closely agrees with the distri- 
bution of its intermediate host, P. surinamensis (Fielding, 1928; 
Sanders, 1929; Schwabe, 1951). 
It is interesting that Ransom (1904), over 20 years before the 
intermediate host was independently discovered by Fielding (1926), 
Sanders (1927), and Kobayashi (1927), observed that the eyeworm 
had been reported only from localities on or near the seacoast. He 
predicted that this restricted distribution indicated “. . . that certain 
conditions, peculiar to the seashore but yet unknown, are necessary to 
enable the parasite to complete the cycle of its development.” The 
distribution of the intermediate host is circumtropical on islands or in 
coastal countries (Schwabe, 1949), thus effectively limiting the spread 
of the parasite to the localities noted by Ransom. 
Family SPIRURIDAE 
Agamospirura parahormeticae Pessoa and Correa, 1929 
Disease.—Pessoa and Correa (1929) were unable to obtain develop- 
ment of encysted larvae that were fed to white rats. They suggested 
that the worm may be parasitic in birds. 
Natural intermediate hosts—Parahormetica bilobata Saussure, 
Brazil, Sao Paulo (Pessoa and Correa, 1929): Encysted larvae were 
found in the visceral cavity. 
Definitive host—Unknown. 
Gongylonema ingluvicola Ransom, 1904 
Disease.—Parasite in esophagus of birds. 
Experimental intermediate hosts—Blattella germanica, U.S.A. 
(Cram, 1935): Larvae of the parasite encysted in the cockroach’s 
body cavity. 
Definitive host —Mountain quail (Oreortyx picta). 
Gongylonema neoplasticum (Fibiger and Ditlevsen, 1914) 
Ransom and Hall, 1916 
Synonymy.—Spiroptera sp. Fibiger, 1913; Spiroptera neoplastica 
Fibiger and Ditlevsen, 1914; Spiroptera (Gongylonema) neoplastica 
Fibiger and Ditlevsen, 1914 (Hall, 1916). Gongylonema orientale 
Yokagawa (Brumpt, 1949).
