tudinally oval-shaped valve, belonging in all probability to the 

 genus Fimbria. It exhibits a regular series of equidistant oval 

 costse with intervening broad sulcations, which are marked by 

 closely-set and fine transverse striae. Only about half the valve 

 is preserved, and this only as an impression in the limestone- 

 matrix ; yet its sculpture is of interest, as suggesting affinities with 

 Fimbria lamellosa of Lamarck — a familiar Eocene shell found in 

 Europe, Northern Africa (Egypt, etc.), Asia Minor, etc. 



The original umbono-ventral measurement of the specimen must- 

 have been about 40 millimetres, and the antero-posterior about 

 60 mm. The posterior side appears to bear a slightly-excavated 

 narrow and elongate area (as seen in a wax-squeeze), which recalls 

 a character more suggestive of Lucina than Fimbria, and therefore 

 the present identification of this specimen must be more or less 

 provisional. 



Locality.— Garrasgooi, 5 miles south-west of Upper Sheikh. 



Collector. — Major E. G. Edwards Leckie. 



Matrix. — The upper or more cherty limestone-beds, showing 

 a reddish tinge. The rock contains Ojoerculina and other fora- 

 minifera (see § F in the Notes on the Eoraminiferal Structures, 

 p. 176). 



(c) Ecliinoidea. 



SCHIZASTER Sp. 



A few remains of Schizaster are represented in these collections, 

 one being an entire specimen, though much worn and without 

 properly-detailed characters. Dr. E. A. Bather is inclined to refer 

 them all to one species ; he states that this 



4 undoubted Schizaster is enough to prove the Tertiary age of this rock, but 

 the ornament and contour of the specimens are scarcely preserved well enough 

 to enable the species to be determined with certainty.' 



Localities. — Top of Garrasgooi Mountain, at about 5200 feet 

 above sea-level, 3 miles south- west of Upper Sheikh ; Main Golis, 

 2 miles south-west from Sheikh Camp ; and near Berbera. 



Collectors. — Major E. G. Edwards Leckie and Dr. Donaldson 

 Smith. 



Linthia (?). 



Another echinoid has been referred doubtfully to the genus 

 Linthia by Dr. F. A. Bather, with the following remark : 



i It is so worn and crushed, and the actinal surface so obscured by hard 

 matrix, which I have not succeeded in removing, that closer identification is 

 not possible on the present evidence.' 



A horizontal section of a small Eotaline is seen, on a fragment of 

 matrix attached to the test of this specimen. 



Locality. — Top of Garrasgooi Mountain, 5200 feet above sea- 

 level, south-west of Sheikh. 



Collector. — Major E. G. Edwards Leckie. 



Matrix. — A cream-coloured limestone.
