Pseudophellia arctica Verrill.

Plate XXXI; Fig. 2. 



This species is one of the few actinians that carry the eggs and young 

 attached to the exterior of the body until they develop. The greater part of 

 the column is covered with a thick epidermal coating, as in Phellia, but it is 

 easily removed. No verrucse nor pores were seen. Sphincter muscle is large, 

 ovate in section. Perfect mesenteries in 24 pairs; their muscles are thick. It was 

 taken north of Bering strait in 30 fathoms (N. Pacific Expl. Exped.) It is, 

 apparently, alhed to Epiactis. The Phellia arcticaf recorded by Murdoch was a 

 rough thick species covered with sand. It was taken in 2^ to 5 fathoms on 

 the Arctic coast of Alaska. Another specimen, perhaps not the same species, 

 was white and translucent. As the internal structure was not examined in either 

 case the identifications are doubtful. 



Family BOLOCERID^ McMurrich. 



Large actinians having numerous stout tentacles which are not retractile, 

 but usually readily cast off. Column usually smooth, secreting mucous abund- 

 antly. No cinclidse nor acontia; usually no suckers nor verrucse. Mesenteries 

 regularly hexamerous; many pairs fertile and perfect. Sphincter muscle 

 relatively small, endodermal, mostly diffuse. 



Bolocera Gosse, 1860. 



Type, Bolocera tuedice (Johnst.) Gosse. 



Carlgren has separated the following species from B. tuediw, with which it 

 had long been united. No doubt they are closely alhed, but our American 

 specimens appear to have much longer and more numerous tentacles than the 

 typical B. tuedice.

Plate XXIII; Fig. 1. 



This is a large species easily distinguished by its smooth, lubricous, stout, 

 usuallv cvhndric, orange or red body, and by the very large, non-retractile 

 tentacles,' easily cast off. It often expands to 150 to 200 mm. (6 to 8 mches) 

 across the tentacles. The longer tentacles are often 50 to 75 mm. (2 to 3 mches) 

 in length, and 10 to 12 mm. in diameter. The body is ordinarily 50 to 75 mm. 

 (2 to 3 inches) in diameter and height, often higher than broad when expanded.
