220 DISCOVERY REPORTS 



The specimens from St. 173 have unusually long primary spines, thus looking rather 

 different from the normal form (Plate II, figs. 1-3). There are, however, no other dif- 

 ferences, and as other specimens are rather intermediate in regard to the length of the 

 spines, I do not think it desirable to designate these specimens by a separate name, not 

 even as a "forma".
