The present investigation is concerned with the detection and mapping of neutral hydrogen in two dwarf elliptical galaxies, including NGC 185 and NGC 205. Both galaxies are companions of M31. On account of the presence of obscuring dust patches near their nuclei, these systems are classified as peculiar. According to Unwin (1980) H I was detected in NGC 205 with the Half-Mile radio telescope. In the current investigation the first detection of H I in NGC 185 is reported, while improved information is provided concerning the H I in NGC 205. The H I in NGC 185 is centered about 30 sec from the nucleus and is not coincident with either of the two dust patches, or the nucleus. NGC 205 appears to have a rotating disk of H I, roughly coincident with the dust and blue star distribution.
