114 G Canadian Arctic Expedition, 1913-1918 



The type specimens were figured as fully expanded. They were yellowish 

 green with dark sap-green suckers, fading out below. Tentacles variable in 

 colour; disk greenish, darker near tentacles; lips flesh colour. Diameter, m 

 expansion, 2-25 inches. 



McMurrich ciuotes Prof. Calkin's notes on the colour. He says the column 

 was greenish yellow above, and yellowish white lower down; tentacles with 

 scarlet or purple tips. The type had the outer tentacles one inch long; inner 

 ones 0-5 inch. It ejected water from small lateral pores "as from a watering 

 pot." McMurrich failed to find any pores in his strongly contracted specimens, 

 but that was not strange, they are often hard to find in alcoholic Sagartiadse. 



Prof. W. K. Fisher has told me that specimens, kept by him in an aquarium, 

 did eject strong currents of water from the sides when disturbed, as when he 

 was cleaning off the mucous, secreted abundantly by them. 



The existence of lateral pores and the ectacmerous condition of the ten- 

 tacles, very unusual in this family, certainly warrant the retention of the genus 

 Evactis. 



Epigonactis Verrill.

 Type, E. feciinda Verrill. 



Two large and remarkable species of this genus have been l)rought in from 

 the fishing Banks, by the Gloucester, Mass., fishermen. Neither of them has 

 been seen in the expanded condition and their colours are unknown. Both 

 carry numerous eggs and young embedded in deep pits on the upper part of 

 the column. 



Thev were tlescribcd and figured bv me in the American Journ. of Science, 

 vol. VII,' pp. 376-380, figs. 35, 36, 1899. 



In internal structure they are similar to Urticina, and doubtless belong 

 to the family Urticinidce. Cajntulum, above the thick collar, is smooth, but 

 sulcated in contraction. 



They seem to be nearest related to PseudopheUia, which carries the eggs and 

 young in the same way, but they do not have the firm epidermal coating present 

 in that genus. The sphincter muscle is largely circumscribed; perfect mesen- 

 teries are numerous and fertile, up to 24 pairs or more. Tentacles are stout and 

 numerous. 



Epigonactis fecunda Verrill, (op. cit., p. 378, fig. 35) came from the Banks 

 oft' Nova Scotia, in 15 to 200 fathoms. 



E. rcgnlaris Verrill, (op. cit., p. 380, fig. 36), came from the Newfoundland 

 banks, in deep water. 



PseudopheUia A'errill. 



PseudopheUia Verrill, Amer. Journ. Science, vol. VII, p. 377, 1899. Type, 

 P. arctica Ver. 



Column, exceptthe capitulum, is covered with a firm epidermal coating; 

 toward the middle it has transverse rows of sunken pits containing eggs or 

 young. Capitulum smooth. Tentacles of moderate size and not very numer- 

 ous. Sphincter muscle is endodermal and circumscrilDed. Perfect mesenteries 

 numerous.
