130 MEDUS.TC OF THE WORLD. 



The species is found in the North Atlantic. It has been taken off the Shetland Islands, 

 between Greenland and Iceland, between Iceland and the Hebrides, in the North Sea, and off 

 the west coast of Greenland. It is probably an Arctic form, of circumpolar distribution. 



Genus CONIS Brandt, 1834. 



(.'own, BRANDT, 1834, Recueil des Actes-seances publ., Acad. Imp. Sci. St. Petersbourg, p. 19 (of the "separate"); 1838, Mem. 

 Acad. Imp. Sci. St. Petershourg, ser. 6, vul. 4, par. 2, p. 355. HAF.CKKL, 1879, Syst. der Medusen, p. 55. 



The type species is Conis niitrnta Brandt of the Bonin Islands, North Pacific. 



GENERIC CHARACTERS. 



Similar to Pandea, but the tentacle-bulbs give rise to special ocellar clubs, which project 

 outward around the margin. The gonads consist of simple, longitudinal swellings on the 

 sides of the stomach and have smooth outer surfaces. The hydroid is unknown. 



Conis mitrata Brandt. 



Conit mitrata, BRANDT, 1834, Recueil Actes publique, Acad. Sci. St. Petersbourg, p. 19 (separate); 1838, Mem. Acad. Imp. 

 Sci. St. Petersbourg, ser. 6, vol. 4, par. 2, p. 355, pi. 2. HAECKEL, 1879, Syst. der Meduseo, p. 55. BEDOT, 1905, 

 Revue Suisse de Zool., tome 13, p. 133 (literature 1834-50). 



Bell 50 mm. high, 35 mm. wide, with a short, conical apex. 64 short tentacles, each with 

 a club-like ocellar bulb projecting from the outer side of the basal bulb at the margin. The 

 tentacles are shorter than the bell-height. The stomach is barrel-shaped, with 4 not very 

 complexly folded lips, having their margins studded with nematocyst-warts. Lips are at a 

 level about half-way between the velar opening, and the inner apex of the bell-cavity. Stomach 

 light-red. Tentacle-bulbs blue. Ocelli black. Bonin Islands, North Pacific. 



Conis cyclophthalma Haeckel. 

 Cmit r\rlo[>hihalma, HAECKEL, 1879, Syst. der Medusen, p. 55, taf. 4, fig. i. 



Bell pyriform, with thin sides and without an apical projection; 15 mm. high, 12 mm. 

 wide. There are 52 tentacles with very elongate, conical basal bulbs, one-third as long as the 

 tentacles themselves. The outer ends of the tentacles are thin and flexible while the basal 

 bulbs are stiff. The tentacles are longer than the bell-height. At the base of each tentacle 

 on the abaxial side of the margin there is a short club-like projection which contains a black, 

 ectodermal ocellus. There are 4 straight-edged radial-canals and a simple ring-canal. The 

 stomach is very large and almost fills the bell-cavity. There are 4 very large, complexly 

 folded lips with their margins studded with nematocyst-warts. The lips are at about the 

 level of the velar opening. (See fig. 69.) 



Haeckel figures and describes 4 longitudinal, swollen gonads on the "perradial" sides 

 of the stomach. Their outer surfaces are smooth and they are filled with ova. He represents 

 them as being completely separated in the interradii. The gonads are probably adradial or 

 interradial ( ?). Color ( ?) 



Haeckel studied a preserved specimen in the Museum of Copenhagen. It was obtained 

 near Gibraltar in lat. 30 iff N., long. 2 23' W. 



Genus CALYCOPSIS Fewkes, 1882. 

 Calycopsis, FEvvk'ts, 1882, Bull. Mus. Comp. Zoo], at Harvard College, vol. 9, p. 304. 



The type species is Calycopsis typti Fewkes, from the Gulf Stream off the coast of the 

 United States. 



GENERIC CHARACTERS. 



Tiarinae with 16 separate, simple, unbranched radial-canals; 4 radial, 4 interradial, and 

 8 adradial. Gonads are composed of a row of leaf-like, transverse foldings along each of the 

 8 adradial sides of the stomach. Lips ( ?) Tentacles simple. Ring-canal simple, without 

 blindly-ending diverticula. Development unknown.
