TABLE 2. Simplicithyris kurilensis Zezina, 1976. Morphometric values of specimen RBINS–INV. 146419 an articulated specimen collected August 13, 1972, off the eastern coast of Iturup Island (co-ordinates 44°37'N/146°57'E) in the Okhotsk Sea, Far East Russia, at a depth between 5 and 60 m. All measurements in mm. L= length of shell, LDV= length of dorsal valve, W= width, T= thickness, WH= hinge line, ØF= maximum width of foramen. L/W= ratio length/width, LDV/W= ratio length of dorsal valve/width, T/W=ratio thickness/width, WH/W= ratio hinge line/width, ØF/W= ratio diameter of foramen/width. LPC= length of pedicle collar, LSP= length of septum, LCP= length of crural plates (in orthogonal projection), WLoph= total width of lophophore, Ø1/2Loph= diameter of one branch of lophophore, Lten= maximum length of one tentacle, Lped=length of pedicle, Wped= width of pedicle.
