In the grouping which he gave in 1908 of the species of Ophiura 

 belonging to the variabilis group, H. L. Clark remarked that O. in- 

 solita also belongs to this group, but that it is incorrect to say, as I 

 have just done, that the second mouth tentacle pores open into the 

 mouth slits. I have considered this point in the remarks which I 

 have made above regarding the arrangement of these pores in the 

 species of the genera Ophiura, Amphiophiura, etc..
