 (1886) pt. ii, pp. 49-55. 



The specific name is given in honour of Prof. J. "W. Gregory, my 

 former colleague in the Geological Department of the British 

 Museum (Natural History), who at the time of the reading of this 

 paper was Professor of Geology in the University of Melbourne, but 

 now occupies a similar position in the University of Glasgow. 



Localities. — Northern Somaliland [B.M.— L. 12666]; and top 

 of Garrasgooi Mountain , at an elevation of about 5200 feet, 3 miles 

 south-west of Sheikh. 



Collectors. — Mr. F. B. Parkinson and Major K. G. Edwards 

 Leckie. 



Matrix. — Cherty limestone, coloured reddish-brown externally. 



Griph^a sp. (PI. XXI, fig. 3.) 



Major Leckie has collected three fragments of a large Gryphcea 

 which, from want of better evidence, it is difficult to associate with 

 any known form of this genus, although possibly they maf be 

 related to an Indian Nummulitic species described by J. de C. 

 Sowerby as Gryphcea globosa? The largest of the pieces represents 

 the central portion of a lower valve, which gives an umbono-ventral 

 measurement of 75 millimetres. It is considerably arched and 

 incurved at the umbonal region, and the external surface, although 

 in a worn condition, still shows some wide lamella? of growth 

 with occasional obscure concentric banding between them. This 

 specimen also exhibits a shell-wall of great thickness (13 milli- 

 metres) at the umbonal arch, which gradually decreases, however, 

 towards the ventral margin,' where it is only about 6 mm. thick. No 

 ligamental or other internal characters are definable. 



Locality. — About 34 miles south of Camp at Upper Sheikh. 



Collector. — Major R. G. Edwards Leckie. 



Matrix. — Cherty limestone, coloured reddish-brown externally, 

 and containing Discocyclina dispansa, Opercidina, and Avhpihi- 

 stegina (see §§ B & C in the Notes on the Foraminiferal Structures, 

 p. 176). 



Vulsella (?) sp. (PL XXI, fig. 4.) 



This specimen consists of a narrow elongate valve, showing a 

 convex and a somewhat acuminate umbonal region, the remainder of 

 the surface being depressed. The lateral margins are imperfect, 

 and consequently the original antero-posterior measurements are 

 unknown. The principal feature of the specimen is its sculpture, 

 exhibiting a regular series of concentric lamella?, which are very 

 thin, nearly equidistant, and smooth. In this ornamentation there 

 is a certain agreement with some forms of Vulsella, recently 

 described and figured by Dr. P. Oppenheim, from the older Tertiary 

 strata of Egypt. 2 But it is hazardous to say more in regard to the
