Benthosema glaciale (Reinhardt) (Text-fig. i8d-f) Position, 13° 25' N., 180 22' W., 28. x. 25, N 450 V, 90o(-o) m. Reg. no. 641-7. Standard length of fish 45-5 mm. Reg. no. 3-12. Between Faroes and Ireland. Standard length of fish 58-5 mm. The swimbladder of this myctophid is thin walled and lies above the stomach. In the 45-5 mm. fish it measured 5-5 mm. in length and about 2 mm. in depth and width at the middle region. A bulbous projection at the fore-end of the bladder contains the three retia mirabilia, which run back- wards to a gas-gland investing much of the floor and side walls. Each rete has a mean length of about 3 mm., the two outer systems being rather longer than the middle. Just behind the base of the bulbous forward projection and on the left-hand side of the swimbladder is a small rounded chamber (the oval) receiving many blood-vessels. The oval has a sphincter-con- trolled opening into the main cavity, while the walls are thrown into radially disposed folds. In the.
