Portion of arms and pinnules from specimen No. 233, natural size; to show therelative proportions of brachials in different parts of arms, or in arms of indi-viduals in different stages of growth. The two large arms are from the samecalyx, beginning about the 25th IIIBr. The other five, of various sizes, belongto as many different individuals; the smallest one, lying upon the upper part ofthe left large arm and down along side it, being almost at the distal end. Inthis figure the dimensions of the brachials in these arms can be compared. 5. Deta
