WY . .4 J .2 On the Mil read. goinp in a southerly direct J o^ m 
south-west pertirn of WY. 4 J, there is found a series of sandstones 
flags and coarse shale, bleached white externally, and capped by the 
Tropidoleptus zone at 133° A. T .This zone presents here the same ap- 
pearance when weathered as in other places ;but the out crop 1 ere dif- 
fers from all other outcrops in that at Lockwood , Trrpidoleptus car- 
inatus is the most abundant species, > elnp pres ert in all stages of 
size and development .Ohonetes scitulus vel coronatus and Spirifer 
granulosus are very ccmror , and Cypri cardella bellastria ta is also 
found here. Gastropoda are also very evident ;but ScMzcphoria im- 
pressa and Atrypa aspera vfc j ch were so very abundant at this horizon 
at Swartwood are here altogether absent or are very rare. For further 
notes on this horizon, see WY.3J4.
