a fact which is more than usually accentuated in the case of Duncan's 

 largest specimen (see PI. XV, Fig. 1), ami although such a phenomenou 

 may be due to some kind of deformity it is possible, as suggested 

 by Dr. Bather, that it may have a wider and more structural 

 explanation. 



Localities. — Duncan's specimens collected by Mr. Bauerman 

 were obtained at Wadi Nagh el Bader, and are preserved in the 

 Museum of the Geological Society bearing the numbers 9003 

 and 9004. The specimens in the Geological Survey of Egypt 

 Collection were obtained by Mr. Barron from the following places : — 

 Wadi el Araba (S f , 4117); Wadi Budra (S -A, 3614), examples 

 numerous and associated with Exogyra Africana ; south end of Wadi 

 el Araba (S-nr, 3815), also found with the above-named shell; 

 head of Wadi Esba (S0-4, 3870), found with Hemiaster Huherti and 

 Exogyra olisiponensis ; Wadi Sifa (S-r/g-, 4021) ; near top of Jebel 

 Safariat (S -/a", 4066), specimens numerous, but with eroded and 

 worn tests, which are generally devoid of detailed characters, except 

 that some of them show the madreporite.

LAST year, while the Port Elizabeth Brick and Tile Company 

 were quarrying a clayey rock at Despatch, near Uitenhage, 

 a number of bones were discovered in the rock. Though the 

 discovery created some little interest, no one seems to have 

 appreciated the scientific value of the find, and large numbers of 

 the bones were made into bricks. A few fragments of vertebrae 

 and ribs have been collected by the Port Elizabeth Museum, and 

 recently an attempt has been made to rescue some more of the bones 

 that still remain in the rock. So far a number of very imperfect 

 fragments of vertebrae — cervical, dorsal, and caudal — a fairly good 

 femur, an imperfect scapula, portions of many ribs, and an ungual
