there are several papillae, only one of them seems as a rule to be fully 

 developed. 



Under the name of Ophioglypha maculata, Ludwig (21, p. 283, 

 PI. 6, figs. 11 & 12) describes a brittle-star from the Bering Sea, which, 

 in general appearance, very much resembles Ophiura robusta. It 

 differs, however, in the absence of papillae at the arm-notches, and in 

 having the papillae along the innermost tentacle-pore joined to the oral 

 papilla. MoRTENsEN (28, p. 83) has pointed out, however, that the arm- 

 notches in Ophiura robusta are sometimes without papillae, a fact 

 which I have also several times had an opportunity of observing. In 

 some specimens, for instance, in the above-mentioned 10-millimetre ones, 

 I found moreover the mouth papillae connected with the adoral papillae 

 of the innermost tentacle-pore, just as in Ludv^^ig's species. I cannot 

 therefore regard Ophioglypha maculata as an independent species, but 

 only as a variety of Ophiura robusta.
