NGC 7335, 7336, 7337, and 7340 are correctly identified by just about everybody except the Lick astronomers who, as Steve Gottlieb notes, have thoroughly mangled the identifications in the area of NGC 7331.
Synonyms: H III-166
Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "eF, vS, E, N.f. and 4 or 5' distant from I.53 [NGC 7331]."
The RNGC (Sulentic and Tifft 1973) notes that this is a 14.5 mag galaxy. Their coded description reads SLEL,BM.

Lew Gramer suggested that I try to view the nearby galaxies in the field surrounding NGC7331, when I posted an observation in July 1997. I could have picked a better night (some nights my l.m. goes to 5.4 or so) but nonetheless, at least one of those galaxies was clearly seen.
NGC7335 is just a few arc minutes to the east of NGC7331, and somewhat similar in appearance. It was about 1/2 the length, and also seemed edge-on, gradually brighter towards the center. It was best viewed 150-250x. It was faint, and best held with averted vision. I could make out it's position angle. I noted that NGC7331 was elongated north-south, turns out that it is PA 170. NGC7335 is about 30 degrees tipped to 7331, at PA 140 or thereabouts, which gives it the appearance of making a triangle with 7331...the two galaxies draw quite near on their northern sides.
In checking a photograph of the area after-the-fact, I noted that NGC7335 was quite difference in appearance than NGC7331, much more of a elliptical shaped galaxy, but was indeed tipped about 30 degrees from the PA of 7331. Also, compared to NGC7331, 7335 was much smaller. A possible explanation for this is that I was not seeing the outer extent of NGC7331, so my size comparison would be off. In fact, I noted with averted vision, under darker skies that 7331 indeed seemed to be much larger.. which would explain the discrepency.
Only fleeting averted vision glimpses of other surrounding galaxies nearby NGC7331 could be made out under these sky conditions. No confirmations made, although they did appear to be where the photograph later confirmed.
