Mr. H. J. Carter on the Fossil Foraminifera of Scinde. 375 



surface smooth, marked with radiating septal lines, for the most 

 part unbranched, flowing in a somewhat sigmoid form from the 

 centre to the circumference. Spire very regular, chambers nu- 

 merous, narrower throughout in the direction of the spire than 

 across it ; septa slightly curved, reflected. 



Largest size. — Breadth ^| inch ; thickness T ^ inch ; number 

 of turns in the spire altogether 9 ; but the outer turns not being 

 approximated, I doubt if this be the full-grown size. 



Loc. Wasna (Major Fulljames). 



Associates. — N. broachensis, Operculina, Orbitoides dispansa. 



Obs. — This little Nummulite was first described in my c Geo- 

 logical Papers on Western India/ p. 696, 1857. For remarks 

 applying to locality, &c, see " Obs." to N. broachensis, with 

 which it is associated. From the richness of the infiltration of 

 red and yellow oxide of iron in this species, I have, as before 

 stated, been able to make out its internal structure even better 

 than if it had been a recent specimen. The whole is identical 

 with that of Operculina arabica, plus the extension of the cham- 

 bers to the centre, on both sides of the horizontal plane, which 

 additional structure is but a repetition in plan of the horizontal 

 one. Even the lines indicating the spicular composition of the 

 marginal cord are visible, although longer than those of Opercu- 

 lina ; but to this I have already more particularly alluded, and 

 therefore need not repeat it here. 



3. N. makullaensis, n. sp. (PI. XV. fig. 4, &c). — Discoidal, 

 rather thick than thin ; margin obtuse. Surface presenting a 

 number of papillae grouped towards the centre, from which deli- 

 cate curved septal lines pass off to the circumference. Internally, 

 spire regular, turns wide and few in number; chambers very 

 narrow in the direction of the spire ; septa much curved and 

 much reflected. 



Largest size. — Breadth ^ inch ; thickness -^ inch ; number 

 of turns 5. 



Loc. Makulla, on the S. E. coast of Arabia. In pinkish 

 limestone. 



Obs. — This is an insignificant Nummulite, but still it is a 

 Nummulite, and therefore shows that the limestone at Makulla 

 is of Eocene era. (See ' Geological Papers on Western India/ 

 p. 614, foot-note.) Its granulated surface at first appears to 

 claim a place for it among the Punctulatce ; but the curved septal 

 lines on the surface, and the curved and reflected septa them- 

 selves internally, together with the narrowness of the chambers 

 throughout, make it rather belong to the Plicate vel Striata. 

 I see no Nummulite in D'Archiac and Haime's Monograph ap- 

 proaching it except the last of this group, viz. N. Heberti. To 

 record the existence of a Nummulite in the limestone at Makulla,
