ResumoThe holotype of Pachycara obesa and a second specimen from off Virginia are described and errors in the original description are corrected. Pachycara obesa differs from all other zoarcids in the following combination of characters: no pelvic fins, no lateral line, 18 to 19 pectoral-fin rays, large gill opening extending below lower edge of pectoral base, dorsal origin above middle of pectoral fin, scales present and deep-water habitat. Known zoarcids found off Virginia and their depth ranges are: Pachycara obesa (2,400-2,450 m), Melanostigma atlanticum (293-1,070 m), Lycenchelys verrilli (260-1,010 m), Lycenchelys paxillus (375-1,535 m), Lycodonus mirabilis (1,271-1,866 m), Lycodes atlanticus (280-1,828 m), and Lycodes esmarki (570-785 m).
