The most notable record, subject to revision whenever more ample material is available, is that of Oflo)itlwliaflorcoKn, hitherto known only from the North Pacific.

Furthermore, the ' ' I'litcrrindcnschicht" is for the most jjart wanting and the superficial cells ahut directly on the much larger interior cells. Tiiese large interior cells are readily visihle (in our fiuid-])resorved material) through the nearly empty and decolor.ate epidermal cells, the rr-lations of the two sug- gesting Kilt zing's unexi)lained figure (i. Two, three, or four of the smaller cells commonly measure the length or width of the suhjaccnt large cells. The super- ficial small cells I're mo.-tly 14-30 n in the long diameter, or sometimes longer; the large interior cells are usually .iO-lOO /u in their longest diameter. Another point in which a cro.ss section diilors from , itzing's figure 1 is the pres(>nce of occasi(Uial rhizoiils hetween the two layers of Large medullary cells. The hleached formalin-- served s|)ecimens are .so translucent that the course of these rhizoids in f- ..vdullary cavity may he ohserved through the two suF)erposed layers ( ' ..us.
