Images of the HH 25/26 and HH 42/128 systems obtained in the emission lines of H2 1-0 S(1), [Fe II] 1.64 mu m, and a 2.22 mu m continuum filter are reported. A series of aligned H2 knots has been discovered in association with HH 26, along with a new infrared continuum source located at the center of a previously-discovered CO outflow which may power the HH 26 knots. HIRES images from IRAS are used to investigate the structure of deeply embedded sources near HH 25 and HH 26. The infrared structure of HH 42 is compared with that seen in visible [S II] emission, and it is suggested that the HH 42/128 system has been produced by episodic outflows from a source located to the southwest of HH 42. Monochromatic [1.64], [2.12], and [2.22] mags are reported for stars detected in each field, as well as H2 and [Fe II] emission-line fluxes for HH knots in each system.
