Japonites decipiens Spath, 1951: 172 (= /. sug- riva,—Arthaber non Diener). Arthaber's type and only specimen of this unusual Scythian species is only mod- estly well preserved, consisting mainly of phragmocone; the adoral 30 mm is body chamber. The specimen measures approxi- mately 89 mm in diameter, mm for the width of the adoral whorl, 29 mm for the height, and mm for the diameter of the umbilicus. The whorls are compressed with convex whorl sides converging to a narrowly rounded venter. The maximum width is at the umbilical shoulder. The umbilical wall is low, rounded, and slopes to the umbilical seam at a steep angle. The shell is preserved only in part, and very poorly; it is apparently smooth except for slightly sinuous growth lines. Spath (1951: 172) expressed concern over Arthaber's (1911: pi. 20(4), fig. 4c) illustration of the suture. A new drawing made from the type specimen is illustrated here on Figure 45A. As with nearly all the specimens from the Subcoliimbites fauna from Albania and Chios, the suture can be developed only by grinding. The suture illustrated here I believe to be a fairly ac- curate representation and does not differ from that reprodu
