is Glob, hulloides. Fig. xiv. Geoponus zeuglodontis {Zeugl.-l.^ 

 is PlanorhuUna vulgaris'^ . 



PI. III. (p. 164), fig. I.-IV., Nonionind^ havarica (Traun- 

 stein), is a young Amphistegina. This is the earliest recorded 

 appearance of the genus in the geological series. Fig. v., 

 Rotalia (Zeugl.-l.) , is a young Oj^erculina or Nummulina? 

 Fig. VI., peculiar triangular dentate cast {Zeugl.-\.), is like the 

 septal plane of a Polystomella. Figs. VII.-IX. (p. 165), Am- 

 phistegina javamca, and fig. X., Heterostegina clathrata^ both 

 from the Orbitoidal Limestone of Gua Linggo-manik, Java, are 

 both the same Amph. javanica. 



PI. IV. (p. 166), fig. I. (p. 167), not named, is an Amphi- 

 stegina with parasitic borings. Figs, ii.-vil. (p. 168), Orhi- 

 toides Prattii. Figs. VIII.-X., Orhitoidesjavamcus^ and fig. XI., 

 Orhito ides microthalama, both from Java, are the same Orhitoides. 

 Fig. XII., Cyclosiphon'^ J from Java, is part of an Orhitoides 

 (referred elsewhere by Ehrenberg to Orh. Mantelli). Fig. Xiii. 

 (p. 169), Spiroplecta'^ {Zeugl.-X.)^ is a Spiroplecta. Figs. 

 XIV.-XVI., Textilaria trilohata (Java, Orb. L.) , is an interesting 

 sublabyrinthic Text.^ already referred to (p. 264). Fig. xvii., 

 >l^/)^Vo/oc^^?^*H,a? (Traunstein), seems to be a Quinquelocidina. 

 Fig. XVIII., Quinquelocidina, and fig. XIX., Quinqiieloculina 

 (Traunstein), are undeveloped young Miliolce. Fig. xx., 

 Quinq. saxorum (Calcaire grossier, Pontoise), is a Quinquelo- 

 cidina, but not of that species which has a thick shell grooved 

 within. Fig. XXI., Triloculina (Orb. L., Java), has been 

 parasitically bored. Fig. xxii., Spiroloculina (Orb. L., Java), 

 is very interesting in having lateral stolons from segment to 

 segment, showing a prolepsis of the more complicated and 

 closely related Orhitolites, the outside of the quasi-annular 

 segments being multistoloniferous. These supernumerary 

 stolons begin by few and become many in later segments. 

 Fig. XXIII. Cerithium'^ {ZeuglA.). Fig. XXiv. Spirillina'^, 

 or young Mollusk ?, or Spirorbis ? (Alabama) ; decidedly a 

 young Mollusk. 



PI. V. figs. I-VIII. Nummulites striata (Couizac, Dep. de 

 I'Aude) ; ^^.Nii.'x^ Nummulinaplanulata {JuSlVO..).. Figs, ix., 

 X. (p. 171), N. Murchisoni (Traunstein) . Fig. xi. N. Dwfrenoyi 

 (Traunstein). Y'xg. ^i\., Polystomatium^ (Traunstein), is a 

 Polystomella. Figs. XIII. -XV., Polystomatium lepactis (Orb. L., 

 Java), is Polystomella craticulata (compare pi. xvi. fig. 9, of 

 'Introd. Study Foram.' 1862). Fig. xvi. (p. 172), Phijsom- 

 phalus porosus (Orb. L., Java), is Operculhia. Fig. xvii. 

 Alveolina (Java), 



* Two casts of this species from North-American Tertiary beds were 

 figured by Prof. Bailey in Amer. Journ. Sc. 1845, vol. xlviii.uo. 2, pi. iv. 

 figs. 30, 31.
