Lophocyrtis View in CoL ex. gr. Calocyclas semipolita Clark & Campbell, 1942 ( Fig. 11I View FIG )
Calocyclas semipolita Clark & Campbell, 1942: 83 , pl. 8, figs 12, 14, 17-19.
Albatrossidium litos – Kozlova 1999: 146, pl. 30, figs 13, 14; pl. 35, fig. 3 (only).
GEOGRAPHIC DISTRIBUTION. — Of Calocyclas semipolita : California; of Lophocyrtis View in CoL ex. gr. C. semipolita: Voronesh Anticline.
STRATIGRAPHIC RANGE. — Of Calocyclas semipolita : middle to latest middle Eocene ( Clark & Campbell 1942; Blueford & White 1984; Blueford 1988); of A. litos : middle Eocene ( Kozlova 1999); of Lophocyrtis ex. gr. C. semipolita : early-middle Eocene (this study).
REMARKS
The third segment of this specimen is longer than that of Calocyclas semipolita typ. and the width of the second and third segments are equal, which also makes difference between this specimen and C. semipolita typ. Kozlova (1999) did attribute the specimens (pl. 30, figs 13, 14; pl. 35, fig. 3 [only]) to Albatrossidium litos . To our point of view this definition is not correct, because the C. litos typ. has a very irregular distribution of pores on its surface comparing to C. semipolita ( Clark & Campbell 1945) .
