Annotated image based on an interpretation of Rimae Riccioli of Lunar Orbiter IV-173-H3 in the on-line version of Bowker and Hughes and Byrne. The original IAU designation seems to have referred to a different rille, barely visible here, extending to the upper right from Riccioli G (the small shadowed crater at about 2 o'clock) towards Hevelius. The IAU nomenclature maps currently apply the name to the rilles within Riccioli itself and possibly to their extensions outside, although the original Rima Riccioli I now seems to be regarded as part of Rimae Hevelius.

Additional Information
Nomenclature
- Named after the nearby crater (Riccioli).
- Page 324 of Neison's book says (pre-IAU directions) that "In the NW wall of Riccioli is a short rille, seen by Lohrman (S202), and SW of it is a long rill ø (S201) extending from Hevel to Riccioli." It is also plotted on his map.
- Mary Blagg's Collated List of 1913 adopted Neison's Riccioli Phi as Catalog Entry 1975 ("NW of Riccioli") and equated it with Schmidt's Lohrmann r.
- The original IAU nomenclature of Blagg and Müller adopted this as Riccioli Ir, and it was the only named rille associated with Riccioli.
- The System of Lunar Craters added a smaller Rima Riccioli II slightly to the north of this as indicated on Quad Maps F4 and F5. This may be the "S202/Lohrmann r" referred to above.
- NASA SP-241 (not an official IAU publication), uses Lunar Orbiter photos to identify what appears to be the SLCs Rima Riccioli I' on pages 321 and 322. The index associates this feature with Entry 1975 in Blagg and Müller. SP-241 does not list or attempt to identify Riccioli II.
- Rimae Riccioli "as assigned to features on the lunar surface" was re(?)-approved by the IAU in 1985 with a notation that it is at 02°N/ 74°W (the current "official" position). No map reference or explanation is given as to whether this an addition to or replacement of the former name; nor is it mentioned whether the rilles inside the crater are included in the new approval.
- The size and position published in the IAU Planetary Gazetteer do not appear to conform to any of the prior definitions. In the new USGS Digital Atlas, Rimae Riccioli is printed over the center of Riccioli (see map links above), and the rille formerly known as Riccioli I is labeled as part of Rimae Hevelius.
- It might be noted that the rille formerly designated Riccioli I, and possibly the one designated Riccioli II, are usually more prominent in Earth-based photos than the ones on the floor of Riccioli.
