Stations 1-6. 



This handsome species is abundant and very variable at the Stations. The 

 largest individuals at Stations 1 and 2. At most of the Stations two distinct 

 types occur, one depressed, with strongly limbate sutural lines, the other a high 

 form with rather swollen chambers, so that the limbate sutiu'es are sunk in 

 sutural depressions. This swollen form is usually smaller than the others, and 

 is covered all over with the characteri.stic orange-brown tint, which in the normal 

 type is confined to a band round the edge of the chambers. This liand may be 

 wholly or partly missing. In a specimen at Station G the clear surface of the 

 chambers was mottled with jiatches identical witji the l)and-coloration, in 

 another the marginal band is so strongly developed that the chamber-surface 

 is reduced to a small square simk in the middle. Fossils occur at Stations 2. 

 3 and G, recognizable by the band-structure, the colour being destroyed.
