The Extreme Ultraviolet Explorer (EUVE) satellite can measure diffuse spectra from 170 to 760\$\,\$\AA~ with a spectral resolution from 17 to 35\$\,\$\AA. EUVE has completed a sensitive all-sky survey in four bandpasses across the EUV. During this time the Deep Survey/Spectrometer instrument was slowly scanning the ecliptic plane by pointing in the anti-sun direction. We present spectra accumulated along a path from galactic coordinates of \$l\$ = \$23.9^{\circ}\$, \$b\$ = \$-27.7^{\circ}\$ to \$l\$ = \$44.1^{\circ}\$, \$b\$ = \$-46.9^{\circ}\$. The ISM can produce a significant flux in this band if there is enough emission measure in the temperature range from \$10^{5}\$~K to \$10^{7}\$~K. No interstellar spectral features were detected, but stringent and astrophysically important lower limits to the emission measure have been determined by folding plasma codes through the spectra.
