Editions by other publishers vary in pagination the newer Penguin editions are 776 pages; the Bantam edition is 886 pages.
Contributors: Please use a 760-page edition (either the original Viking edition with the orange cover or the Penguin USA edition with the blue cover and rocket diagram there are plenty on Ebay for around $10) or search the Google edition for the correct page number.

627.28-29 Commas, brimstones, painted ladies
Three taxa of butterflies. The Comma (Polygonia c-album) is one of the anglewings; sulfur-yellow brimstones are in the genus Gonepteryx in the family Pieridae; painted ladies are in the genus Vanessa. The Comma is named for a so-shaped white mark on the underside of its hindwing; a similarly-marked North American congener is called the Question Mark (P. interrogationis).
The Uffizi chase scene Pynchon is referencing here may be from one of the six vignettes that comprise Roberto Rossellini's Paisà (1946), a military travelogue, following Allied (mainly American) soldiers during the 1943 invasion of Italy as they eventually wrest the country from Fascist control. In one of the vignettes, a nurse and her friend are running through the maze-like Uffizi, its treasures packed in crates, trying to cross into occupied Florence.
The Statue of Liberty references the final chase scene in Alfred Hitchcock’s Saboteur (1942).
