Body thin and elongate, with 6-8 dark pigment bands.
Attains 12 cm. Taken once off Port Elizabeth in the
Agulhas Basin, 4360 m; also in North Atlantic.
76.1 Bathymicrops regis: 10 em SL.
Genus Bathypterois Gunther, 1878
Pectoral fin with uppermost 2 rays joined and greatly
elongated; the tiny rudimentary rays always present at top
of fin, and those sometimes present between the upper and
lower section are omitted from the counts. Eighteen
species; 5 in our area; 3 others probable: B. grallator
(Goode & Bean, 1886), B. longipes Gunther, 1878 and B.
viridensis (Roule, 1916). Shcherbachev (1981: 57) recorded
"Bathypterois sp. 2" from off our area and compared it with
B. atricolor; Shcherbachev's species may pertain instead to
B. ventralis Garman, 1899, which has P with 11-14 rays in
lower half, V 9, LL 57-59, and a subcaudal notch.
