The 19th star above is Sham, the Arrow, not a part of the Archer, but rising only 4.6 days later than Alrami. Number 19 is a Sun number and as such indicating a final, e.g. because the Mayan had an odd 5-day long month at the end of their 365 (= 18 * 20 + 5) days long year.

The Manubrium (ο) is interesting. It could indicate where Sea is beginning (in January 4) and it could possibly allude to the Yoke of the Sea:

... σ, with ζ and π, may have been the Akkadian Gu-shi-rab-ba, the Yoke of the Sea ...

The manubrium bone (red) is located in the horizontal center of a pair of bones which if joined will look like the Archer's bow. The arrow on this bow is hitting the head above.

Hevelius has Manubrium (ο) at the neck, with π at the back of the Archer's head and ξ at the other end of what looks like a short chain of stars.

Al Baldah (π) is on the side of Nunki (beyond the end of the 19th hour) while ξ is on the side of Ascella (before the 'break' between the 19th and 20th hours).

Ascella (ζ) means Armpit (Latin Axilla), where also Hevelius has put this star.

Obviously the images in Ca9-17 and Ca9-20 could allude to Ascella. Antares (in November 25) is like Nunki, the sign of a new season ahead:
