*939- Velata aubryi (Douv.) ; Stefanini : 186, pi. 20, figs. 10, 11 ; pi. 21, fig. 1. 



1952. Eopecten aubryi (Douv.) ; Cox : 31, pi. 3, figs. 8-10. 



i960. Eopecten aubryi (Douv.) ; Joubert, pi. 8, figs. 1a, b. 



i960. Eopecten abjectus (Phillips) ; Joubert, pi. 7, fig. 7 (non Phillips sp.). 



Material. Several specimens, one ex B.P. Coll. 



Localities and horizons. 3! miles W. of Melka Biini, N.E. Kenya ; Callovian, 

 Rukesa Shales. Muddo Erri, 12 miles W. of Rahmu, N.E. Kenya, Kulong, 2 miles 

 to the S.W., and S. of Rahmu-Melka Murri road, 6 miles W. of Rahmu ; all Callovian 

 [?-Lower Oxfordian], Muddo Erri Limestones. Manyuli stream, just W. of Nautope, 

 Mandawa-Mahokondo anticline, Tanganyika ; Callovian. Mandawa-Lonji creek 

 traverse, Mandawa area, Tanganyika ; Upper Oxfordian. 



Remarks. Specimens from N.E. Kenya are mostly quite typical of this species, 

 as described in the works cited above, although the one figured under the name E. 

 abjectus by Joubert (i960) has very unevenly spaced ribs. Those from the Upper 

 Oxfordian of Tanganyika, while agreeing with the typical E. aubryi in the number, 

 equality, and fairly regular distribution of the main radial ribs, differ in the almost 

 complete smoothness of the intervals, which bear at the most a faint median riblet, 

 finer interstitial threads being absent. There are insufficient grounds at present for 

 distinguishing them even as a new sub-species, although they seem to be of rather 

 later age than the hitherto recorded range (Bathonian-Lower Oxfordian) of E. 

 aubryi. There are three specimens of the right valve of this species in the material 

 studied, and their ornament consists of numerous fine, subequal, weakly granose 

 radial riblets.
