EgAnl477-61 and EgAn3782"62 , These two viruses, isolated from Sylvia 
-^rruca , are related by CF (Ati 1477-61 ascitic fluid with homologous titer 
of 1:128 reacts 1:4 with An3782“62; An3782-62 ascitic fluid with homologous 
titer of 1:512 reacts 1:128 with Anl477-61), They, as well as EgAnl398-61 
from Cotumlx coturnix , have been tested with 81 specific and 16 grouping 
ascitic fluids of arboviruses and probably represent new, previously un¬ 
described viruses (Table 21)• 
Serological study of Balagodu (1633970 ), 164434 , and 166414 from India n 
Balagodu (1633970) from the paddy bird ( Ardeola grayii ) has been identi¬ 
fied on the basis of CF and HI tests as Ingwavuma using both the South African 
prototype virus and the Q3488-9 Ingwavuma strain isolated from Cyprus from a 
spring migrant. The existence of Ingwavuma virus in India greatly enlarges 
its geographic range and strengthens the hypothesis that migrating birds are 
responsible for its transport from one geographical area to another. 
164434 virus from Ardea cinerea has been identified by CF test as 
Nyamanini virus or a very close relative. Nyamanini is also known from Egypt 
and South Africa and has been previously isolated from cattle egrets and Argas 
ticks. 
166414 virus from Ardeola grayii has been identified by CF test as Thimiri 
virus (see above), in the Simbu group. 
In addition, results of CF studies of BeAnl41106, Cali-874, Conn Anll4, 
166413, 166415, 166416, and IbAn28946 are shown in Table 22. These bird viruses 
remain ungrouped.
