tion of the well-preserved original ; it seems, therefore, to me not rea- 

 sonable to create a new species because it is derived from a different 

 locality, but shows again the coincidence of the African and Indian 

 Cretaceous deposits. 



Locality. Umtamfuna river, bed e. In India : Pondicherry. 



Solarium Wiebeli, nov. sp. PI. III. fig. 6. 



Angle 130°. Number of whorls 5. 



The surface perfectly smooth, only the lines of growth are faintly 

 visible ; but neither transverse striae nor ribs can be distinguished, 

 as in Solarium jaulchellum, Baily, from the same stratum ; in shape 

 also this species varies much from Baily's Solarium, which pos- 

 sesses gradually widening whorls, whilst in the present species each 

 whorl is double the width of the preceding one.

Chemkitzia xjiirDosA, Sow., spec. 



Ghemnitzia unclosa, Forb. 



Scalaria undata, D'Orb. 



Turritella (^Ghemnitzia) Meadii, Baily. 



Ghemnitzia Sutherlandii, Baily. 



Mr. Baily caUs a small Ghemnitzia, which shows slight spiral lines, 

 Turritella Meadii ; but it is, I think, only a young individual of 

 his new species Ghemnitzia Sutherlandii, which can be identified 

 with some varieties of Ghemnitzia undosa, Forbes. The last whorls 

 do not show the transverse lines so distinctly ; and altogether it is 

 impossible to find two specimens which show exactly the same 

 ornamentation of surface. The older whorls are always more di- 

 stinctly ribbed, but not the later ones. In fuU-grown specimens, 

 the spiral lines, which even in young ones are very feeble, dis- 

 appear.

 galum, KuUigoody, Alundanapooram, Serdamungalum, Anapaudy,

EUCHRYSALIS GIGANTEA, Stol. 



This is the species erroneously referred by Bailey to Turritella 

 Renaucciana, D'Orb. 



Locality. Umtamfuna river, bed e. In India : north of Alun- 

 danapooram, east of Anapaudy, Comarapolliam. Trich. & Arr. Gr,

A small fragment of a smooth Dentalium, which it is not possible 

 to identify with any already described species.

Numerous small specimens, imbedded in the sandstone with Am- 

 monites and other shells, beds d and e.
