stigma^ and fig, 17, Gr. rhomhoidale^ are various Textilarice'^ 

 figs. 8-14 and 17 are of the gibbosa-gvoiiY>, with tendencies 

 towards the aggJutinans type; figs. 15 & 16 belong to the 

 sagittula type. Fig. 18, Gr. jphyUodes^ seems to be Bolivma 

 punctata (?). Fig. 19, Gr. thebaicum (?), with its delicate 

 misty shell, is probably Virgulina Heniprichii, which will be 

 further noticed in describing the next plate. Fig. 20, Gr. at- 

 tenuatuni (?) may be a small Textilaria ; indeed it corresponds 

 with the first few chambers of fig. 17. Figs. 21, Gr.phyl- 

 lodes (?), 22 & 23, Gr. attenuatum (" Text, acicidata^ 1838, 

 proves to be fragments of several small species of Grammo- 

 stomum^'')^ and 24, Strophoconus'i [Gram.'^) teretiusculus^ are 

 rather broad individuals of Bolivina punctata^ or may be 

 grouped as B. dilatata. Fig. 25, Proroporus ? ( Grain. ?) pachy- 

 derma^ passes well as a coarse-shelled Text. aggJutinans. 

 Figs. 26 & 27 (■?), Polymorphina gyzensis (" compare Grammo- 

 botrys and Sjjhceroidina^^), evidently a puzzling form to the 

 author, is especially so as a figure. It has relatively large 

 swollen segments, like a full-plaited " chignon," and has the 

 aspect of a Polymorphina in some respects ; but it shows no 

 aperture, and is probably a Textilaria. 



Figs. 28, Rot.alia aspiera^ and 29, Planulina globigerina (?), 

 are Planorbidina tuherosa, varr., near PI. Haidingerii. The 

 next three are probably Globigerinm — namely, figs. 30, Rotalia 

 incresceyiSj 31, Planulina Isidisj and 32, Allotheca rotalia 

 {^^Rotalia globulosa^ 1838 "). Figs. 33 & 34, Gloligerina cretce 

 {^^ Rosali?ia foveolata, 1838"), is the typical Glob, bulloides, 

 D'Orb. Fig. 35, Planulina Pharaonunij is a variety of Pul- 

 vinnlina Menardii, near pulchella. Fig. 36, Plan, incurva^ 

 answers to Plan, ariminensis. Fig. 37, NonioninaHemprichii, 

 is very near N. scapha. Fig. 38, Planulina pyramiduw. 

 ("1838; small specimen "), is without doubt an Opercxdina 

 complanata. Fig. 39, Plan.l eurytheca is a young Planorbu- 

 lina, probably of the amnionoides group. Fig. 40, Rotalia 

 incrassata {^^ Planulina turgida, 1838^^) may be catalogued 

 as a small Cristellaria cidtrata. Fig. 41, Planulina heptas.^ 

 is a young Planorbidina farcta^ sublimbate perhaps, but 

 scarcely to be referred, for want of specialization, to any par- 

 ticular variety, though probably tending towards PI. ammo- 

 noides. Figs. 42 & 43, Planulina lenticidina ? (" compare 

 Rotalia lenticuh'na^^). Here we have gradations of form from 

 the loosely set, lobate, round-chambered (42) PI. globuJosa 

 (Ehr.), through a more compactly grown shell (43), to figs. 41 

 & 39, above noticed. 



Figs. 44, Planulinal eurytheca^ and 45, PI. hexaSj belong to 

 Cristellaria cultrata ; the latter figure shows a very slight
