Two new species, Silicula beringiana and S. okutanii, are described from the northwestern Pacific. These species have an elongate shell with extended and tapered posterior end, differing from each other in form and proportions. Silicula beringiana was found in the Bering Sea, Kamtchatky Strait, and near the southeastern coast of Kamchatka (Pacific Ocean) at 489–4,984 m depth. Silicula okutanii was found in the Pacific Ocean at a latitude of the northern part of Japan at 5,219–5,352 m depth. Silicula sandersi (Bernard, 1989) and Propeleda soyomaruae (Okutani, 1962) were re-examined. Based on comparison with the description, pictures and photos of the type species of Silicula Jeffreys, 1879, Lamellileda Cotton, 1930, Poroleda Hutton, 1893, and Propeleda Iredale, 1924, the following combinations are suggested: Lamellileda sandersi Bernard, 1989, and L. soyomaruae (Okutani, 1962).
