Sectio, Lagenicula. Age, Upper West- 

 phalian B and above (?). 

 Note. — May be closely allied with Triletes 

 translucens. 



70. Triletes saarensis Zerndt, 1941, Paleonto- 

 graphica, Abt. B, vol. 84, p. 134, pi. 12, figs. 

 40-44.

 and B., comb. nov. 



Sporonites saturnoides Ibrahim, 1932, 

 Neues Jahrb., Beilage-Band 67, Abt. B, p. 

 449, pi. 16, fig. 26. 



Zonales-sporites saturnoides (Ibrahim) 

 Ibrahim, 1933, Sporenformen des Aegir- 

 horizonts, p. 27-28, pi. 3, fig. 26. 

 Age, Upper Westphalian B.

72. Triletes sextus S. W. and B., nom. nov. 



Triletes VI Bennie and Kidston, 1886,

 9, p. 109, pi. 3, figs. 6a, 6b, 6c. 



Sectio, Aphanosonati. Age, Lanarkian=: 

 Namurian. 

 Note.— Forms of this sort are included by 

 Zerndt (1931, 1934) in Type 14. Inasmuch_ as 

 this was used as the type for Apiculati-sporites 

 Ibrahim, it seems desirable to have an orthodox 

 designation for reference. 



7?). Triletes sextusdecimus S. W. and B. nom. 

 nov. 



Triletes XVI Bennie and Kidston, 1886, 

 idem. pp. 113-114, pi. 5, figs. 16a, 16b, 16c, 

 16d, 16e. 



Age, Bernician and Lanarkian = ap- 

 prox. Upper Dinantian and Namurian. 

 Note. — Related to Triletes superbus, and prob. 

 to T. circumtextus and T. brasserti. This form 

 ■was taken as the type oi Zonales-sporites Ibra- 

 him, hence it seems desirable to propose an 

 orthodox name for purposes of reference.

 B., comb. nov.

 Sectio, Auriculati. Age, Upper West- 

 phalian B (Laziska series). 

 Note. — The group is clearly distinguished 

 specifically by coarse reticulation, in this respect 

 somewhat similar to Triletes tuberculatus, 

 though in shape it resembles Triletes auritus. 

 Possibly it represents a connecting link between 

 these species. It is named for Zofja Kowalew- 

 ska Maslankiewiczowa who provided an ample 

 description of the form. 



77. Triletes sparassus Murray, 1939, Geol. 

 Mag., vol. 76, p. 480, p. 482, figs. 3, 4.

 figs. 36, 37. 



Sectio, Aphanosonati. Age, Upper Di- 

 nantian, Lower Namurian. 

 A^o^^.— The lageniculate vestibule possessed 

 by this form is insufficient basis for assigning 

 it to Lagenicula in disregard of its other charac- 

 teristic Aphanosonati features.
