288 Messrs. Parker and Jones on 



and, 38, PI. eusticta, are common, yomig, sublobate and lim- 

 bate Planorhidince glohulosce (Ehr.). Fig. 39, Planulina sy- 

 riaca^ is a Planorhidina like PI. Haidingeri. 



Fig. 40, Plamdina umhilicata^ is a small ill-grown Crtstel- 

 laria cultrata. Fig. 41, Plan, menibranacea^ is Pulvimdina 

 Karsteni. Figs. 42, Ptygostonium senariunij and 43, Pt. quina- 

 riuni^ are young specimens of Planorhidina vulgaris^ coarsely 

 porous, lobate, limbate, and with patulous apertures. Such as 

 these soon take on an irregularly concentric growth, with bi- 

 er multi -osculate chambers. Figs. 44, Planulina leptostigma^a., 

 45, Rotalia ammonis, 46, PI. cornu, 47, PI. leptostigma, /8, 

 and, 48, Rotalia depressa, are young forms of Planorhulina 

 {Planulina) ariminensis. 



A. Grains of the limestone (magn. 300 linear), consisting 

 chiefly of Foraminifera, with some Coccoliths (?) and stellate 

 spicules (?). Magnified 300 diam. 



This Foraminiferal fauna lived at about 30 or 40 fathoms 

 depth. 



(IX.) PI. XXV. II. B. Figs. 1, 2, Nodosaria lihanotica, =N. 

 ovicula, with thick-shelled and elongate chambers, near N. 

 Marice, D'Orb., and N. (D.) Lorneiana, D'Orb. 



Fig. 3, Grammostomum polystigma, is Textilaria sagittida. 

 Fig. 4, Oi'. convergens, is T. agglutinans. Fig. 5, Rotalia ihex, 

 is Planorhidina ariminensis. Fig. 6, R. senaria, is a small 

 limbate Planorhidina. Fig. 7, R. laxa, the same as fig. 4, the 

 young of Planorh. vulgaris. Fig. 8, Nonionina Astrcea, is too 

 porous and has its chambers relatively too large for Nonionina: 

 it seems to stand between figs. 28 & 32, more delicate and 

 neater than either in its shell and pores ; the setting-on of the 

 chambers is Nonionine or Operculine, and too symmetrical in 

 appearance even for Anomalina among the Planorbulines. 

 We must leave it doubtful. Fig. 9, Rotalia quaterna, j3. 

 Jloscularis {" comiynYG Planulina Jlod^^) J is a yowag Planorh. 

 farcta. Fig. 10, Planulina septenaria, is a young PI. vulgaris 

 with rather falcate chambers. Fig. 11, PI. ampliata, is Pla- 

 norh. ammonoides. Figs. 12-15 are stellate spicules ; figs. 16, 

 17, enlarged Cyatholiths and fragments. 



B. Grains of the limestone, consisting of Foraminifera, 

 Coccoliths, &c. Magnified 300 times linear. 



Belonging to about 30 or 40 fathoms depth.
