 tooth, the front much longer than the bind margin and (Lucas' figure) bluntly 

 produced beyond base of the comparatively short, strongly curved, serrate 

 finger (Czerniavski figures a much shorter palm of gnathopod 2 in d, and 

 adds, that in 9 gnathopod 1 has the 5*^ Joint short, palm of &^^ not convex,
