deina nitida. Except its recent mention by name amongst 

 the species found by the Rev. A. M. Norman in the dredged 

 material obtained on the " Valorous " cruise, I cannot find 

 that it has been the subject of actual observation with any 

 author since d'Orbigny's time, and hence conjectures as to 

 its position and affinity have fallen somewhat wide of the 

 mark. Max Schultze, in his scheme of classification,^ places 

 Candeina in the Subfamily TJtellida, between Guttidina and 

 Globidina, two sections of the genus Polymorpliina ; and 

 Von Keuss,- after expressing uncertainty as to its right zoo- 

 logical position, suggests that it possibly represents a new 

 and distinct family, or if not, that perhaps it might be classed 

 with the PolymorphincB. 



The genus Candeina does represent a distinct type of Fo- 

 raminifera, but not a distinct family. Its affinity is to Glo- 

 higerhia^ and, with specimens to refer to, its characters are 

 easily comprehended. The test is spiral and trochoid, the 

 segments globose, and usually three to each whorl. The 

 earlier chambers are minute, the later ones relatively 

 very large; the test is exceedingly thin and smooth and has 

 a slightly yellowish tinge ; the perforations are so fine that 

 under a moderate magnifying power it appears imperforate. 

 Instead of a single general aperture it is provided with a 

 series of little rounded orifices, following the septal lines, 

 most noticeable on the sutures of the later chambers, and 

 seen on both the superior and the inferior surface of the test. 

 In this respect it resembles tlie Glohigerince of the "rubra''' 

 group, but the orifices are smaller and more numerous and 

 they are regularly disposed. 



I have found Candeina nitida amongst other pelagic 

 Foraminifera from one surface gathering (Philippine 

 Islands). Its occurrence in the "Challenger" bottom- 

 dredgings is pretty much confined to the South Atlantic and 

 South Pacific. D'Orbigny states {loc. cit.), "Nous n'en avons 

 qu'une seule espece des Antilles. Nous dedious ce genre a 

 M. Ferdinand de Cande." 



Notes on Pelagic Foraminifera. 



The employment of the towing-net during the cruise of 

 the " Challenger " to an extent never before attempted, 

 and the careful preservation of the animal and vegetable 

 organisms collected by its means, have furnished the ground- 

 work, not only for a better appreciation of the nature and
