Very sparingly distributed. At Stn. 7 the only individual observed was large and 

 microspheric. At the other Stus. they were small and megalospheric.

Generally distributed, but never abundant. Most of the specimens are of the typical 

 elongate form, the best being at Stn. 9. At Stns. 2 and 6 specimens passing into 

 *S^. limbata d'Orbigny were found. At Stn. 7 the agglutinate type occurs.

14 Stations. 



Generally distributed, especially at the southern Stns., and often abundant. 

 Terquem's specific name is used to designate sulcate Spiroloculinse of many different 

 types. At Kerimba, as elsewhere, most of the specimens are referable to sulcate or 

 striate forms of the simple type *S'. nitida, but at several Stns., especially Stns. 10 

 and 12, many specimens might equally well have been treated as sulcate varieties of 

 S. enccavata and S. planulata. At other Stns., notably Stns. 1, 9, and 11, specimens 

 weFi common in which the sutural lines were so deeply excavate that the shell was
