158 DR. CHARLES CHILTON ON THE SUBTERRANEAN 
and was first pointed out by Vejdovsky ; the lower margins of 
the first four side-plates are supplied with a few sete, each 
arising from a slight indentation of the margin; this has been 
rather exaggerated in his figure 1, so as to make it appear as if 
the margins were actually crenate. His fig. 3 is more correct, 
though even here there is rather more crenation than in the 
specimen. 
Accessory branchiew have been described by Vejdovsky on the 
last three segments of the pereion; similar appendages had 
previously been described by Wrzesniowski in Boruta and 
Goplana.
