The male (5.30 and 6.20 cm) specimens appear to be mature, while the female (9.40 cm) was mature with ovaries containing numerous mature and immature, spherical, pale-colored, opaque, yolked oocytes, ranging in diameter from 0.20-2.12 mm; from gross observation, there appear to be fewer than 100 eggs in each ovary. Specimens were collected with a 60 cm bongo net, epibenthic sled and bottom trawl (Ref. 82595).
