what longer than the outcr, conical and in contracted State long- 
itudinally sulcated. Oral disc radially furrowed. Longitudinal muscles 
of the tentacles and radial muscles of the oral disc very well devel- 
oped with high, dichotomically ramificated folds. Two deep siphon- 
oglyphes with long aboral prolongations. Actinopharynx with numer- 
ous longitudinal ridges. Pairs of mesenteries in variable numbers 
unto 48. 2 pairs of directives. All or most mesenteries perfect. 
Muscle pennons strong, diffuse, in the youngest mesenteries more 
concentrated. Parietobasilar muscles very strong, formirig a distinet 
projection, some of its part enclosed in the mesogloca. Basilar 
muscles very strong. Nematocysts of the column 19—22 x almost 
2 /f, those of the tentacles 29—34 x almost 2 ^ — alm. 2,5 /i, 
those of the actinopharynx 23—29 (31)X2Xwell 2,5/^. Spirocysts 
of the tentacles 22 x almost 2—53X4,5 
Colour: Column white and red in alternate longitudinal lines, 
the red in small irregular spots, the white markings more or less 
elliptical (S tue key), striped vermillion and whitish-yellow (Cough- 
trey). Tentacles duli white, often with tips manoe, or light-brown 
(Stuckey), yellowish*white; or sometimes purpie (Coughtrey). 
Oral disc reddish brown, marked in radiating lines by the insert- 
ions of the mesenteries. Peristome of darker colour (Stuckey). 
Column with red stripes (Mortensen). In preserved State in 
formaline: Column yellowish-fleshcoloured, the tentacles somewhat 
darker (Mortensen’s specimens); in alcohol?: yellowish (Steph¬ 
en so n). 
Dimensions of the largest specimen: hight 5,5 cm, breadth 
of the pedal disc 4 cm, breadth of the column mostly 3,5 cm (height 
6 —7 cm, breadth 4—5 cm, tentacles 2,5 cm, Stuckey). 
Occurrence. E.of North Cape. 55fms. Hard bottom. 2.1.1915. 
6 specimens. (Mortensen). 7 miles E. of North Cape. 70 fms. 
(British Antarctic-Exp. teste Stephenson). Debora bay. Port 
Chalmers (teste Coughtrey). Cock strait from Plimmerton to 
Seatown, littoral (teste Stuckey). 
Exterior aspect. The exterior of Morten s en’s specimens 
agrees with that given by Stuckey and Stephenson. The number 
of tentacles were in 4 specimens 82, 82, 87, 96, while Stuckey 
States 60 and Stephenson 96. The arrangement is probably hexam- 
erous although from the stage with 48 tentacles to that with 96
