We report the results of a visual search for galaxy candidates in an area of twelve square degrees covered by the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire-3D (GLIMPSE-3D) Spitzer Legacy programs. The areas searched consisted of three 2x2 degree blocks, with galactic coordinates centered at (330, -02), (330, +02) and (331, -02). All three regions were imaged for 2.4 seconds in the 3.6, 4.5, 5.8 and 8.0 µm bands using IRAC on the Spitzer Space Telescope. We report a total of 114 galaxy candidates, yielding an average of 9.5 candidates per square degree. We also show that the galaxy detection rate is dependent on galactic latitude, probably due to the lower diffuse 8 micron background at high latitudes. We have found that the detection rate increases from 4 per square degree (at b=1º) to 12 per square degree (at b=3º). We present the physical parameters of these galaxies, discuss their clustering, and note which have been previously detected in other wavebands/surveys. This work was supported by the National Science Foundation's REU program and the Department of Defense's ASSURE program through NSF Award AST-0453442.
