Description. Shell of moderate size for family, length to 10 mm, diameter not exceeding 2.6 mm; glossy white, up to 14 whorls; whorls nearly straight-sided; growth scars few, irregular in position. Length 8-10 mm.
Type Locality and Type Specimens. San Pedro, Los Angeles County, California. Holotype: USNM 109641. Melanella micans borealis: Comax, Vancouver Island, British Columbia; holotype: USNM 150954. Material Examined. California: Santa Maria Basin, Phase I, sta. 21, 49 m (1). Other material: 63 lots in the LACM collection.
Distribution. Kachemak Bay, Alaska [LACM 80-74.8] (59°N) to Isla Cedros, Baja California [LACM 71-158] (28°N). Habitat Soft bottoms, 20-90 m. A single LACM lot from San Pedro, Los Angeles County, California, is annotated: "off sea cucumbers" (figure 1.13D).
Remarks. This is a smaller species than Balcis micans, but is much larger than the following species. Bartsch's Melanella micans borealis is here added to the synonymy of Balcis oldroydae. The name is emended to oldroydae because Bartsch indicated that it was named after Mrs. Oldroyd.
