[[underlined]] Ateles [[underlined]] ssp., Oct. 30, 1960, V  

[[image - three red vertical lines and a red hash mark continuing down the page in the left margin]]

It is possible that some (but not all) of what I recorded as "silent PL" performances by young Spiders in my earlier notes were really PL & Snorting
As a result of my observations of young Reds during the last 2 days, it is possible to make a list of the display patterns performed by animals ⅓ to ½ grown:
1. MO
2. BT
3. PL
4. Lsh 
5. Sct
6. Squ - "WW"
7. S [[Till?]]
8. B (probably not well differentiated into Agg. and "Ord").
9. Snorting
10. MFB 
11. Screams
? 12. "Chewing".
Young infant Reds probably perform all these patterns [[underlined]] except MFB [[underlined]] , as soon as they begin to move around independently a little (although I don't think I have ever seen a really young infant perform BT or Sct which I was sure was really ritualized).  The B performances of young infants are probably always shorter, even less differentiated than those of older young

I have not seen enough of the behavior of both Blacks and Reds to be absolutely sure that there is no difference between them. It seems likely however, that they are either identical or very similar. Possibly the Blacks lack Lsh's. Possibly young Reds do less B than young Blacks.  But I rather think that these differences will disappear upon further study.

Transcription Notes:
Following the format of previous pages I've put the circled page number at top. Ateles is latin name for spider monkeys - for more info refer to google. Notations/drawings in margin are impt. as it is the writers code for the type of monkey he is discussing. I'm still unsure (and it is consistent through the whole project what the [[Till?]] abbreviation means? Will ask TC for more info. For the abbreviations see previous pages in project. MFB = muffled barking
