larger ones, to which the part of the curve to the right of this depression refers, 
and which are 63-122 » long, have anchor-teeth distally rather divergent. The 
smaller ones, to which the part of the curve to the left of the depression refers, and 
which are 17.5—52 uw long, have anchor-teeth distally nearly parallel. I therefore 
also divide the micramphidises into two subgroups: — large and small micram-
