We present 21-cm observations and models of the HI kinematics anddistribution of NGC 4244, a nearby edge-on Scd galaxy observed as part of theWesterbork Hydrogen Accretion in LOcal GAlaxieS (HALOGAS) survey. Our modelsgive insight into the HI kinematics and distribution with an emphasis on thepotential existence of extra-planar gas as well as a negative gradient inrotational velocity with height above the plane of the disk (a lag). Our modelsyield strong evidence against a significantly extended halo and instead favor awarp component along the line of sight as an explanation for some of theobserved thickening of the disk. Based on these models, we detect a lag of -9+3/-2 km s-1 kpc-1 in the approaching half and -9 +/-2 km s-1 kpc-1 in thereceding half. This lag decreases in magnitude to -5+/-2 km s-1 kpc-1 and-4+/-2 km s-1 kpc-1 near a radius of 10 kpc in the approaching and recedinghalves respectively. Additionally, we detect several distinct morphological andkinematic features including a shell that is probably driven by star formationwithin the disk.
