Besides the above I have identified a good many others with 
more or less certaiut}’. In the foraminifera-rocks I have come 
across the following among others 
Periphaena decora Halioma ociilatum 
Spongosphaera rhabdostyla Lithocyclia ocellus. 
I have not done more work in the identification of the 
radiolaria and diatoms j^artlj’ on account of the difficult}' alreadv 
mentioned of isolating and mounting them and partly on account of 
the un.scientific way in which they have been named. What are 
evidently merely individual forms have been describee! as genera 
and species. There is little satisfaction therefore in working at 
the nomenclature of these organisms until someone undertakes 
the task of its revision and simplification, in fact to do for this 
subject what Parker, Jones and Brady and Carpenter have done 
for the Foraminifera. 
As regards the Foraminifera which con.stitute the most im- 
portant element of this Microzoic fauna and the one I am best 
acquainted with, I have introduced some slight changes from my 
former paper. A few names I was not quite sure of have been 
omitted including some forms of doubtful validity and a few 
I have since discovered have been added. There are still some 
whose affinities are undetermined. Of the forms whose names 
are given there are .some which are marked varieties or show 
constant differences from the types and these may probabh- here- 
after receive distinctive names. The foraminifera of the radio- 
larian marls are generally ])oor and small examples. 
Several of the Microzoa are of limited occurrence and verv 
few indeed pa.ss through the series. Globigerina occurs most 
abundantly in all the beds except the shallow water ones, namely 
the Orbitoides and Amphistegina beds and the Ally creek shell- 
bed. The Nummuline forms (Orbitoides, Nummulina, Heteros- 
tegina, Amphistegina and Tinoporus) are confined to these beds. 
The following occurred each in a single sample of rock from the 
Globigerina beds ; Anomalina polymorpha, A. anoniala. 
The following are also of very 'restricted occurrence though the 
first three are tolerably abundant in the beds in which they occur. 
Miliolina (several forms) 
Amodi.scu.s incertus, A. charoides 
Discorbina bertheloti ^ 
Pulvinulina menardi - Very rare. 
Nonionina (one or two species) ) 
Another very rare form is one I have not yet determined — 
this is like a Glandulinain shape but ajipears to unite some of the 
characters of Lagena and Miliolina (Biloculina). I do not say, 
however, that it really combines the characters of those groups.
