iNlr. A, (iil)\ ^laitland (1924 ]) H9) siinis up the position as 
follows: — “In the iieigh])ourho()d of Daudarraj^au is a belt of' white 
clialky limestone wliicdi there seems some sound reason ft>r 
bclievinj>‘ to be the northern extension of tlie (tiiigin beds. Air. 
Alailtand’s caution is fully Justified for litliolo^ical characters 
and sucli vague palaeontological evidence as ‘‘fragments of 
I itocrraniKs' ’ and ‘‘specimens of Oslrra'’ do not warrant a more 
definite statement . 
The Giiigin series at Dandarragan o(‘cu])ies a strij) of country 
several miles in width running in a northerly direction froi/i 
Yatheroo, It consists of horizontally bedded chalk, ‘‘green- 
sands, ’’ marls, clays, etc., with occasional bands of more resistant 
ferruginous sandstone and comj)acted layers of j)liosphatie nodules, 
and is covered, in ])laces with the remnants of an uncomformable 
lateritic capping. 
As a result of irregular denudation, two series of low hills 
have been developed, the westerly ridge, according to (!ampb(‘ll. 
being capped with sandstones, whilst the undulating eastern seric^s, 
in the district that I examined, are in part i>rotected by lateritic 
material. 
The rich black soil i-esulting from the disintegration of the 
chalk and the gravelly residue of the weathered laterite Tisually 
ol)Scure the underlying rocks on the hill sides, but the stee]) gullies 
so chai-acteristic of the “limestone country” often present inter- 
esting sections. In a short gully on the northern side of Houn 1 
Hill, “,Kayanal)a” an exposure of chalk bearing fragments of 
Inoceramus was considered suitable for further investigation, I 
therefore selected a site and made an interesting collection from 
a band of approximately twelve inches in thickness, situated about 
three feet alcove the Ijase of th exposure. As the relationship ot 
this exposure to the chalk as a whole is not determined, the posi- 
tion of the ‘ ‘ zone ’ ’ is also uncertain. 
Great care was taken whilst the collection was being made and, 
though a number of small forms were lost, because of the strong 
wind that was blowing, these, fortunately, were mostly recognised 
as belonging to the commoner species. The specimens obtained 
include the common Trigonosemus, Magadiiia, Magas, Mytihis^ 
Inocemmus, Camptonectcs as Avell as Uiiitacrinus^ Maisupitcs^ 
Echinid spines, etc 
No special search was made for Alicrozoa, such as Foramiiji 
fora and Ostraeoda, but about twenty Eoraminfera were obtained
