Characters. — This form slio-ws five angles in its end view; the weaker 

 individual figured by d'Orbigny as LamarcJdana has only four projecting 

 chambers (1. c, fig. 15). Thus both differ from M. triangularis so far as the 

 relative protrusion of the chambers is concerned, but not essentially otherwise. 



Occurrence. — Miliolina Guvieriana is essentially a shallow-water form. The 

 type-specimens were obtained by d'Orbigny fi:'om the shores of Cuba and 

 Jamaica. Those mentioned in the 'Challenger' Report are from Japan, the 

 Eastern Archipelago, and the Philippine Islands, and were found at depths 

 ranging from six to ninety-five fathoms. As a fossil this species apparently 

 occurs rarely. It has lately been found in the Miocene of Muddy Creek 

 (Victoria) ; and the Crag specimens were obtained from Gomer (Gedgrave).
