Shields with few conspicuous transverse lines, their edges 

 rounded. Intermedial shields very large, oval. Tail 2'/, times 

 as long as trunk. Inferior cristae of trunk and tail continuous; 

 median cristae of trunk rectilinear, ending on last ring of 

 trunk. Head more than 10 times in length, 2' .^ times in trunk. 

 Snout extremely short, as long as diameter of eye and half

Note. We are not sure that this species is different from 

 N. subosseiis Giinther from West Australia but the lastnaraed 

 species is as yet represented only by a dried male specimen 

 in the British Museum and not in a state that the fin-rays 

 could be counted and the end of the median cristae ascertained.
