NGC 2586  (08h 24.5m  -04° 56')
Discovered by Muller (II).  There is a triple star at the NGC position on
the POSS although the other members of this group were placed 1.0 tmin too
far E by Muller. RNGC misidentifies this number with a faint galaxy.
Confirmed by Harold Corwin.

NGC 2674  (08h 48.2m  -14° 17')
Discovered by Stone (I).  Harold Corwin notes that the ID is uncertain, 
but N2674 possibly refers to the galaxy at 08 49 13  -14 17.7 (2000).  
This position is 1.2 tmin E of Stone's position and matches in dec.  
Not found by Howe on 2 nights.  Not listed in DSFG.  Listed as uncertain 
NGC ID in ESGC.

NGC 2757  (09h 05.4m  -19° 03')
Discovered by Muller (II).  Described as only an eF D*, dist 12" by Howe.
Harold Corwin proposes a closer triple star (Muller would have resolved 
the coarser double) at 09 05 25.7 -19 02 52 (2000).

NGC 2952  (09h 37.6m  -10° 12')
Muller's position in list II is 2.0 tmin too far E and 3' N.  This galaxy
is very faint and not found by Bigourdan, so identification is uncertain
according to Harold Corwin.  Listed as nonexistent in RNGC and not in 
RC3 or DSFG.

NGC 3133  (10h 07.2m  -11° 57')
Discovered by Leavenworth (II).  The RA is 1 tmin too far W and 10' N
(unusually large error in dec!). This gx was not found by Bigourdan and it
is not listed in MCG or RC3.  Leavenworth gives a mag of 16.2, so this gx
must be extremely faint.

NGC 3176  (10h 15.3m  -19° 01')
Discovered by Stone (I).  Not found by Harold Corwin or Carlson and 
listed as a dubious object by Hagen.

NGC 3355  (10h 43.5m  -23° 12')
Discovered by Langley (Annals of Harvard Observatory, Vol 13, #215).
Simply described as "found in search for Biela's comet; place approximate."

Not listed in any modern catalogue except ESO which lists a possible
equivalence with M-4-25-58 = E501-G79 = A1039-23 (RC2).  This galaxy is
located 2 tmin W and 11.4' S of Langley's position.  ID uncertain.

NGC 4994  (13h 09.8m  -23° 23')
Discovered by JH (h3471). N4994 is possibly E575-065 (from PGC errata list)
which is 0.4 tmin W and 4' S of JH's position.  Another possibility is a a
50' dec error would make N4994 = III 766 = N4993 (from Harold Corwin).
