The UZC-SSRS2 Group Catalog
We apply a friends-of-friends algorithm to the combined Updated ZwickyCatalog and Southern Sky Redshift Survey to construct a catalog of 1168groups of galaxies; 411 of these groups have five or more members withinthe redshift survey. The group catalog covers 4.69 sr, and all groupsexceed the number density contrast threshold, δρ/ρ=80. Wedemonstrate that the groups catalog is homogeneous across the twounderlying redshift surveys; the catalog of groups and their membersthus provides a basis for other statistical studies of the large-scaledistribution of groups and their physical properties. The medianphysical properties of the groups are similar to those for groupsderived from independent surveys, including the ESO Key Programme andthe Las Campanas Redshift Survey. We include tables of groups and theirmembers.

Neutral hydrogen observations of four MKW-AWM poor clusters
The Arecibo 305-m telescope was used to make neutral hydrogenobservations of the poor clusters MKW 7, MKW 9, AWM 1, and AWM 3. Theobservations are almost complete for MKW 7 and AWM 1 galaxies brighterthan 15.7 mag within one-half of a degree of the D or cD galaxy, and forMKW 9 galaxies brighter than 15.7 mag within one degree of the D galaxy.Both the integrated H I profile and the sensitive upper limits of the HI flux density are examined, and 22 new redshifts are reported for the Dgalaxy. The 18 galaxies closest to the dominant member of the D galaxyhave an average hydrogen mass-to-light ratio of 0.20 solar units, with astandard deviation of 0.12. The ratio is lower than that measured forlate-type spirals found in loose groups or in isolation, and is similarto the ratio determined for late-type galaxies near the centers of Abellclusters. A correlation between galaxy size and distance from the D orcD galaxy is found in the examination of the MKW-AWM clusters. However,the weak correlation may in fact be that between galaxy size and surfacedensity, or a consequence of the larger members' direct tidalinteraction with the dominant galaxy.
