We present initial results from a redshift survey carried out with the LowResolution Imaging Spectrograph on the 10~m W. M. Keck Telescope in the HubbleDeep Field. In the redshift distribution of the 140 extragalactic objects inthis sample we find 6 strong peaks, with velocity dispersions of${\sim}400${\kms}. The areal density of objects within a particular peak, whileit may be non-uniform, does not show evidence for strong central concentration.These peaks have characteristics (velocity dispersions, density enhancements,spacing, and spatial extent) similar to those seen in a comparable redshiftsurvey in a different high galactic latitude field (Cohen et al 1996),confirming that the structures are generic. They are probably the high redshiftcounterparts of huge galaxy structures (``walls'') observed locally.Comment: 14 pages, including 2 figures, to appear in ApJ Letter
