Degner (1925) described M. schmidti from a single squid, 46 mm ML, that had both tentacles intact.
- Inner rings of arm suckers with 13-14 slender teeth distally; 11-12 broad, short teeth proximally (Degner, 1925) (drawing at near right).
- Arm sucker 0.15 mm in diameter (Degner, 1925).
- Club length 60% of tentacle length (Degner, 1925).
- Proximally suckers in 7 series; become 20-23 series by distal third of club (Degner, 1925).
- Club suckers with smooth inner rings; outer rings with 13 placks medially; long pegs (3-4 times others) on distal placks (Degner, 1925).
- Club sucker 0.05 mm diameter (Degner, 1925).
- Funnel locking-apparatus with tragus and antitragus (Degner, 1925).
- Tubercules absent from mantle and elsewhere.
- Fin length (without tail) 65% of ML (without tail); fin width 79% of ML (without tail) (Degner, 1925).
- Integumental photophores present over entire body, including dorsal surface of fins (Degner, 1925).
- Eyelid photophores absent.
- Color in alcohol pale brownish with dark scattered chromatophores.

M. schmidt is not clearly differentiated from M. grimaldii or M. agassizii. In both species eyelid photophores about the same size as the integumental photophores could have been overlooked. We place this species in the synonomy of the first-named species M. agassizii.
Type locality: North Atlantic, Bay of Biscay at 46°30'N, 7°00'W.
