Both in fig. 2 and fig. 4 the body is tapering to a point as in spe-des of Sepia, of which some have a rostral thorn. This point ismore distinct in fig. 4 than in fig. 2, and may be explaned as adisappearing larval excrescence. It is probably an important onto- 10 O.

LovÉNs original description vs^as based on a specimen from Fin-mark. I have caught R. glaucopis at different times of the year andat many localities in the Trondhjem region from Frøyf jord to Beit-stadfjord in depths of ca. 50 to 350 m. In spite of its common oc-currence in the Trondhjem Fjord it is probable that this speciesshould be considered as an arctic one. D i s t r i b u t i o n. — East Spitsberge
