We describe near-IR imaging data for a sample of 23 class I sources in theTaurus-Auriga dark clouds. Combining our data with previous photometry, wedetect brightness variations of 0.1-0.5 mag in many sources. The near-IRmorphologies are consistent with mm continuum measurements. Most (60%) of thesample are true protostars; the rest may be objects in transition between classI and class II, T Tauri stars with edge-on disks, or heavily reddened T Tauristars.Comment: 15 pages, 3 tables, 4 figures; to appear in the June 2002 Astronomical Journa
