PAKAGOBIODON Bleeker. 

 Paragobiudoii Bleeker, Arch. Neerl. 1875, 309 {melaiwsoina). 

 This well-marked group is distinguished by the very ch.iDby body, subglobular head, short cup- 

 shaped ventrals, and by the presence of numerous short prickles or filaments on the head. The scales 

 are large, the sides of the head naked and the fins short. The lower jaw has 2 small canines. The 

 resemblance of these species to Oohiodon indicates no close affinity.
