,- ZOANTHARIA 



the ctsophageal region were fairly well developed. The longitudinal muscles on the macro-mesenteries 

 are fairly strong but form few folds. The parieto-basilar muscles are very weak and narrow. The 

 distribution of the longitudinal and parieto-basilar muscles on the body-wall is quite distinct. 



The filaments have the usual structure. The nematocysts of the glandular tract are 34 41 p 

 long and 10 12 ft broad (very seldom only gju broad). They are uniformly broad and very common 

 and there is also a frequent occurrence of thick-walled capsules with distinct basal part to the spiral 

 thread (length 22 26^). 



The sexual organs were undeveloped in the two specimens sectioned in the sexual region.

Dimensions. The column measures about 2'ocm. in height, 0-6 cm. in breadth at the base, 

 0-6 07 cm. broad at the uppermost extremity and 0-4 cm. broad at the middle (Daniels sen). Spec- 

 imens from Umanak fjord, which were considerably larger than the specimens of E. glacialis I have 

 seen from the Norwegian North Atlantic Expedition, had in the preserved state a length of about 

 1-8 cm. and a breadth of 0-6 cm., the smallest breadth being 0-4 cm. 



Colour. The incrusted portion of the body is greenish-yellow but when the animal is extended 

 almost yellow, having a somewhat greenish play of colour at the base only. The oral disc is faint 

 brick-red with darker folds round the oral aperture. The tentacles are more intensely red than the 

 oral disc, but are somewhat paler in colour at the extremities (Danielssen). In alcohol dirty 

 yellowish.
