Characters. — This is an ovate (or rather obovate) BuUmina, allied to B. affinis 

 and pupoides, d'Orb., but ornamented with exogenous shell-growth in the form of 

 prickles attached either to the earlier chambers only, or to the edges and sides of 

 the same in the aftergrowth. The ornament varies considerably in amount. In 

 our fig. 1 in Plate III it appears to be scanty, or it may have been worn off. 

 Williamson's B. S'pinidosa, and the bizarre Soldanian figures associated with 

 B. aculeata in the 'Ann. Mag. Nat. Hist.,' 1871 (see above), may be taken for 

 extreme examples. 



Occurrence. — BuUmina aculeata has a very wide geographical range, but affects 

 more especially the deeper waters. It has been found as far north as the north 

 coast of Norway, through the temperate and tropical seas ; and as far south as the 

 Antarctic Ice Barrier. Its bathymetrical range extends from 75 to 2740 fathoms. 



Its earliest recorded geological occurrence appears to be in the Miocene of 

 Vienna. It has also been found in the Pliocene of Italy, Garrucha (South Spain), 

 and St. Erth. So far as the Crag is concerned, we have nothing to add to the record 

 from the Upper Crag of Southwold given in the First Part of the Monograph.
