 [Cibicides refuhjens) is a bad copy of Soldani's fig, oo. 



Both Soldani and D'Orbigny have been misled by the iso- 

 morphism which exists between the two groups Planorbuliua 

 (including I'runcatidina) and Pidvinnlina, in associating the 

 two figures nn and on under the same name. It is difficult to 

 speak with certainty from engravings on copper, in a matter 

 re(|uiring nice discriminati(^n with respect to shell-texture and 

 the like; but we feel assured that the first figure [nn^ repre- 

 sents a Pulvinulina — the Iiotalina truncatnlinoides of D'Or- 

 bigny (Foram. de Canaries, pi, 2. figs, 25-27), a subvariety 

 of Pulvinulina }fcnardii, and near P. ^lirhcliniann. P.
