586 ME. P. CHAPMAN ON TBE CONSOLIDATED [Aug. I9OO, 



Nonionina communis (d'Orb.). Frequent. 

 Potystowtella striatopunctata (F. & M.). Oomnion. 

 Amphistegina Lessonii, d'Orb. Common. 

 ? Operculina sp. Very rare. 



There were also present in the crushed material several specimens 

 of ostracoda, much worn and polished, and apparently belonging to 

 the genera Paracypris, Cythere, and Cytheridea. 



II, Junagarh. Near the Girnar Hills. — A granular cal- 

 careous rock, but with mineral particles derived from igneous rocks, 

 cemented by calcareous material. One can distinguish many speci- 

 mens of foraminifera, including Pulvinulina (thick forms, littoral 

 rather than pelagic in habitat). Numerous fragments of lamelli- 

 branch- and gasteropod-shells are also present in this rock. 



III, 165 A. Near the Girnar Hills (3 miles away); about 

 SO miles from the sea. — A gritty or pebbly calcareous rock of a 

 pale ochreous yellow, very incoherent in texture. 



This rock differs in several points from the preceding. It is com- 

 posed of coarser granules, and the calcitic cement is more coarsely 

 crystalline. Molluscan shell-fragments are numerous, as also 

 echinoderm-spines, with occasional fragments of Lithothamnion. 

 It is this rock that shows the best examples of the infilling of 

 foraminifera. The latter are numerous, and in the rock-sections one 

 may detect Miliolina, Globiyerina, Rotalia, and Amphistegina. These 

 forms are fairly common, with the exception of Globigerina, of which 

 there is only one example. I have obtained some very perfect and 

 beautiful casts of foraminifera from this rock by treating it with acid ; 

 with these occur also casts of the borings of the perforating alga 

 in the molluscan shells, and many echinoderm-spines, similar to that 

 figured by Carter, 1 but ascribed by him to ? Nodosaria spinicosta, 

 d'Orb. These casts are apparently composed of limonite and 

 haematite ; and Carter also found this latter mineral constituting the 

 casts. 



Besides the mineral particles, which Dr. Evans has found to be 

 derived partly from quartz-keratophyre and partly from basalt, there 

 are oolitic granules, and a large number of coprolitic (?) bodies of 

 an ovoid shape. 



The separate grains forming this rock are somewhat rolled, but 

 are not coated with secondary mineral matter, being merely cemented 

 in the matrix. 



IY, 279 M. Chorwar Road, nearly 10 miles from the 

 sea. — A yellowish, almost salmon-coloured limestone, too compact 

 to be termed a calcareous sandstone, somewhat cavernous. 



In this rock there is more cementing-material than in the two 

 preceding, and the calcite is clearer and more definitely granular. 

 The organic and other particles are here distinctly outlined with a
