32 Records of the Indian Museum. [Vol XXII, 1921.] 



cimens to Acanfhophihalmus from which Blyth's genus is distin- 

 guished chiefly by the absence of the ventral fius. I have carefully 

 examined the two unique type-specimens preserved in the Indian 

 ^Museum and a large series of fresh specimens of Acanthophthalmus 

 pangia from Manipur. I do not find anj^ trace of the ventrals or 

 of accidental injury in the former. Moreover, I cannot distinguish 

 Blyth's specimen from AcanthobhthahnH^ pangia except by the 

 absence of the ventrals. I am, therefore, led to believe that the 

 specimens of Apiia were abnormal and that the genus Apua can- 

 not stand distinct from Acanthophthalmus. 



I conclude, therefore, that the cases of Apua and Channa are 

 not to be considered parallel. Channa has been found by numer- 

 ous collectors at many different places over a very wide area and 

 the ventrals are invariably absent. Apua, on the other hand, has 

 only once been collected and only two individuals were then found. 



I have carefulh- dissected a specimen of Channa burmanica, 

 Chaudhuri, and have not been able to find any trace of the pelvic 

 girdle.
