provided with such, as they have seen a zooid under one of the preserved developed polyps). When 

 the authors attribute cells in the developed polyps to their .Gunneria>>, and figure such a polyp 

 with a cell in fig. 9, it is to be observed that this figure cannot exactly be called a true representa- 

 tion of fact, nor does the description correspond with it. Kophobelemnon has not a real calyx, nor has 

 this specimen; only a superficial examination could so misinterpret the features arising from the different 

 degree of retraction of the polyp-body and the tentacles. Otherwise, it will be found that the special 

 statements of the authors with regard to the form of the spicules, the strong equipment with spicules 

 of the tentacles and polyp-body, the pigmentation of the pharyngeal sac and gastric filaments 

 etc., correspond exactly with the features in Kophobelemnon. It might be supposed that Danielssen 

 and Koren have never made a comparison with this form, as any one who compares the Gunneria- 

 specimen with a Kophobelemnon (.moebii-), must be struck immediately by the similarity; even by a 

 comparison of the not quite correct figure 8 with the corresponding part of a Kophobelemnon of a 

 suitable size, the agreement will easily be seen; it seems to me superfluous, therefore, to enter into 

 any further details. 



Distribution and Occurrence. -- The stations of the Ingolf> extend the known territory 

 of the species considerably: 



81.40: 62oo'N. Lat, 21 36' W. Long., depth 845 fathoms, bottom temp. 3-3 C. 

 . 10 : 64 24' 28 50' 788 3-5 



24: 63 06' 56 oo' 1199 24 



> 28: 65 14' 55 42' 420 3-5 



The steamer Thor has further added as new localities: 63 05' N. Lat, 20 7' W. Long., 557 

 metres (St. 167 of the Thor, south of Iceland, H/ 7 1903). Here 14 specimens were obtained, of which 

 the largest is io5 mm long with 12 polyps, the smallest 5o mm with 7 polyps. Further: 62 57' N. Lat., 

 19 58' W. Long., 957 metres; here three specimens were taken: two small young stages with solitary 

 primary polyp, the one only 8 mra long and very small, with one large and two quite small zooids; 

 the other 24""" long, rather big (ca. 2 mm broad), with a polyp-bud just appearing on the right side 

 and with many and large zooids; the third specimen 55' nm long, damaged, with several polyps and 

 large zooids. 



Apart from the coast-regions of Norway where the Vest Fjord (ca. 67 68 N. Lat.) is given as 

 its northernmost occurrence, the species has not hitherto been known farther north than 60 i8'N. Lat, 

 in the Fierce Channel (the Triton Exp. St. 8), whilst its most westerly occurrence on the European side 

 of the Atlantic did not extend much farther than 10 W. Long., west of Brittany (the Porcupine Exp. 

 1870; see Kolliker, Monogr. p. 370). Now its territory is seen to extend, not only to Iceland but across 

 the Denmark Straits and quite into the Davis Straits, west of Greenland; its occurrence there further 

 corroborates my supposition that the Kophobelemnon occurring farther south on the east coast of 

 America belong to the same species. Formerly, it was known from many of the Norwegian fjords and the 

 adjoining coast-regions, viz. from the Vest Fjord and farther south through the channel of the Skager 

 Rak to the Christiania Fjord and to Bohuslan; also from many places in the Faeroe Channel; off 

 Brittany; from the coast of Les Landes: from different places in the Mediterranean (Cape Beam, Nice
