Dimensions of two .specimens: Spec. 1) expanded, length cm, breadth about cm. Spec. 2) contracted, height 1cm breadth of the pedal disc 1,4 cm, inner tentacles about cm long. Occurrence: Danniark Strait 64°44'N. 32°52'W. ]H3H m. Temperature at the bottom ' (Ingolf exped. St. 92) 7 specimens. Exterior aspect: The examples were very badly preserved and strongly contracted .so that I cannot give anv good descrip- tion of the species. The column, certainly divisible into scapus and scapulus as I have observed fragments of a cuticle incrusted with foreign botlies in a specimen, is according to the state of contraction conical or cylindrical. In the latter case, when the body is more expanded, the ami distal ener (2 specimens examined). Especially the outer tentacles are thin in the expanded .state and not provided with thickenings at the The inner tentacles are more than twice as long as the outer ones. The oral disc is rather wide and radially sulcated, about half the disc is devoid of ten- tacles. The actinopharynx is well <levelope(l and sulcated. 2 well developed siphonoglyjdis, running out in aboral prolongations, are present. -Vnatoniical description: The ectoderm of the column is high, the endodermal ci
