The plotted points represent the spacing of the baleen plates in individual whales. (Black symbols represent South African whales and circular ones South Georgia whales.) VENTRAL GROOVES The description already given of the ventral grooves in Blue whales may be taken as applying also, in almost every particular, to Fin whales. A minor distinction perhaps is to be found in the posterior endings of the grooves. In Blue whales they may end evenly in the neighbourhood of the umbilicus but in many cases may be continued beyond this point in the form of irregular or broken up extra grooves and there may be a median groove joining the umbilicus and genital aperture. In Fin whales, on the other hand, the grooves always end very evenly near the umbilicus, and the median
