Two new species of Liparidae (snailfish) Paraliparis macrocephalus sp. nov. and P. rossi sp. nov., captured in the south‐western Ross Sea, Antarctica (74–75° S; 165–171° E), are described and illustrated. Paraliparis macrocephalus resembles, but is distinct from P. hubbsi , P. valentinae , P. somovi and P. aspersus. Paraliparis rossi is similar to P. macrocephalus in meristic counts, pectoral girdle structure and morphometry but differs in size of cephalic pores and nostril, shape of teeth, colour and other characters. Paraliparis macrocephalus was captured in the deepest locality in the Ross Sea, the Drygalski Trough, a 1200 m deep inner‐shelf depression. As trawling was preceded by video camera tows, a description of the substratum and fauna of these little‐studied trough habitats is also provided.
