inner rays are well developed in my specimen; according to 

 Hora the two innermost are very small and rudimentary or the 

 fourth ray may be absent; the body is elongate, compressed, 

 as is the naked head ; the minute eyes are more or less invisible, 

 covered with skin; two rows of teeth in each jaw, the outer
