talia rudis {'' B. laxa, juv.?") ; 37, 38, R. glohulosa (1838) ; 

 Sd, B. lepfosjytra', 40, B. senaria] 41, B.? 2Jertusa {'^ BosaUna 

 pertusa, 1838, in part"). 



Fig. 42, Botalia pachyphysa, is a young lobulate PJanorhu- 

 lina farcta, near P/. {Tnincatulina) lohatida. Figs. 43, Bot. 

 quaterna, 13. Jlosculart's (" compare Plamdina flos "), & 44, a,h, 

 Planulina jporosa [^^ Bosalina Icevigata, 1838, in part"), are 

 small Planorlmlince Haidingerii (D'Orb.). Figs. 45, Plan, 

 centoculus, and 46, PL megarporn, are characteristically the 

 young of Planorbulina vulgaris. Fig. 47, Planulina Jlos 

 (" compare Botalia quaterna, ^.Jloscularis "), is a young deli- 

 cate Planorbulina Haidingerii. Fig, 48, Planulina dep)ressa, 

 is a young Planorlndina, with granular or rough surface, near 

 Haidingerii, possibly PI. Ungeriana. Fig. 49, Glohigerina 

 foveolata {^^ Bosalina foveolata, 1838"), is the typical G. cre- 

 tacea, D'Orb. (see above). Fig. 50, Planulina prorotetr as, is 

 a roundish Planorbulina tuberosa (F. & M.), or may be said to 

 be the spiral centre of a Planorbulina of the vidgaris subtype, 

 which would afterwards grow less regularly and become out- 

 spread with somewhat concentric chambers. The notch of the 

 aperture on the right-hand side of the figure is characteristic. 

 Figs. 51, Planulina millepora, and 52, PI. pardalis, are Pla- 

 norbidina [Anomalina) ammonoides (Reuss). Fig. 53, Proro- 

 spira princeps, is Planulina ariminensis, D'Orb. Figs. 54, 

 Planulina ampliata, and 55, PI. ammonis, are Planorbulina 

 ammonoides. Figs. 56 & 57, PI. integra (56, w^ith entire 

 margin ; 57, sublobate), are small Planorbidina;. Figs. 58, a,b, 

 PI. heterojjora, are Planorb. ammonoides. Figs. 59, PI. ? umhi- 

 licata (" PI. millepora, juv.?"), probably the young of fig. 62, 

 QO, PI. ampliata (?), 61, PI. integra, 62, Botalia Hemjwichii 

 (rough shell, with rapid increase of the whorls), are all P^cmor- 

 bulince, near PI. ammonoides ; or these, with the foregoing, 

 may be described as spiral beginnings of such Planorbuline 

 varieties as grow in outspread forms in the shallow water, 

 and, when attached, become mostly thick-walled. 



Fig. 63, Planidaria thehaica, is probably a small Cristellaria 

 {Saracenaria) italica. Fig. 64, Sjyiroloculina dilatata. From 

 the aspect of the sheU, it seems to have become smoothly and 

 finely arenaceous — an interesting feature. Fig. 65, Quinque- 

 loculina ? nodulus. A Quinqueloculina, probably Q.semimduni ; 

 but it seems to be the central portion only. 



Figs. 66 & 67 are stellate spicules (?). 



A. Fine dust, mainly composed of Coccoliths [cyatholiths) &c. 

 B. Group of the Foraminifera without the finer particles. 



These belong to a depth of about 30 or 40 fathoms.
