The $\textit{Fermi}$-LAT Collaboration recently presented a new catalog ofgamma-ray sources located within the $40^{\circ} \times 40^{\circ}$ regionaround the Galactic Center~(Ajello et al. 2017) -- the Second Fermi InnerGalaxy (2FIG) catalog. Utilizing this catalog, they analyzed models for thespatial distribution and luminosity function of sources with a pulsar-likegamma-ray spectrum. Ajello et al. 2017 v1 also claimed to detect, in additionto a disk-like population of pulsar-like sources, an approximately 7$\sigma$preference for an additional centrally concentrated population of pulsar-likesources, which they referred to as a "Galactic Bulge" population. Such apopulation would be of great interest, as it would support a pulsarinterpretation of the gamma-ray excess that has long been observed in thisregion. In an effort to further explore the implications of this new sourcecatalog, we attempted to reproduce the results presented by the$\textit{Fermi}$-LAT Collaboration, but failed to do so. Mimicking as closelyas possible the analysis techniques undertaken in Ajello et al. 2017, weinstead find that our likelihood analysis favors a very different spatialdistribution and luminosity function for these sources. Most notably, ourresults do not exhibit a strong preference for a "Galactic Bulge" population ofpulsars. Furthermore, we find that masking the regions immediately surroundingeach of the 2FIG pulsar candidates does $\textit{not}$ significantly impact thespectrum or intensity of the Galactic Center gamma-ray excess. Although theseresults refute the claim of strong evidence for a centrally concentrated pulsarpopulation presented in Ajello et al. 2017, they neither rule out nor providesupport for the possibility that the Galactic Center excess is generated by apopulation of low-luminosity and currently largely unobserved pulsars.
