The example here described was collected at Dongorreh by 

 Mrs. Lort-Phillips, its matrix containing Amphistegina, Opercu- 

 lina, etc. (see § in the Notes on the Foraminiferal Structures, 

 p. 177). There is a second specimen of this variety, which was 

 obtained by Mr. F. B. Parkinson at the same place, and was 

 erroneously recognized as Nerinwa allied to Benauxiana, d'Orb. 1 

 A further specimen was collected by Major E. G. Edwards Leckie 

 about 4 miles south of Camp, Upper Sheikh, at an altitude 

 of over 5000 feet, showing similar lithological characters to the 

 others. It is, however, of smaller size, having a basal diameter of 

 55 millimetres, although the whorls are of precisely the same type 

 of structure as that described. 



Localities. — Dongorreh ; 4 miles south of Camp, Upper Sheikh. 



Collectors. — Mrs. Lort-Phillips, Mr. F.B. Parkinson, and Major 

 R. G. Edwards Leckie. 



Matrix. — Heavy cherty limestone, red-stained externally. 



Campanile somaliensis, sp. nov. (PI. XVIII, figs. 1 & 2.) 



There are two limestone-casts now to be noticed, of still larger 

 proportions than those previously described, which apparently 

 belong to one and the same species. The best-preserved and largest 

 of these exhibits a conically-shaped body of oblong circumference 

 with the four last whorls, all the earlier ones being absent. The 

 latest whorl shows a maximum height of 72 millimetres, while the 

 penultimate measures 40 mm. in the same direction, the next giving 

 a height of 35 mm. The basal diameter of the specimen measures 

 165 by 145 mm. Its base is much covered with matrix, but con- 

 centric plications are observable round the columellar region, where 

 a flattened area is noticed circumscribing the axis. The whorls of 

 this specimen are not funnel-shaped anteriorly, nor is the suture 

 so deep as in the forms previously described. Moreover, it is doubt- 

 less of much shorter spire also, and is probably a form not yet 

 described. Indications of a short anterior canal are also present. 



The smaller of these specimens (having a diameter of 135 by 

 120 millimetres) has been cut through longitudinally, for the exposi- 

 tion of internal characters. This exhibits a wide cylindrical axis 

 showing columella-plications, having on each side large quadrate 

 chambers with rounded outer margins, and curving obliquely and 

 anteriorly inwards. 



Locality. — Specimens collected by Dr. Donaldson Smith in the 

 neighbourhood of Berbera, and presented to the British Museum 

 (Natural History) by the Gaekwar of Baroda. 



Matrix. — A cream-coloured cherty limestone, containing Orbi- 

 toides, Operculina, etc. (see § L in the Notes on the Foraminiferal 

 Structures, p. 176).
