470 Verrill, Notes on Badiata. 



verrueose and attaching foreign substances, or of becoming low, round- 

 ed, slightly prominent papulte, or they may be entirely contracted to 

 the level of the general surface, which then appears nearly smooth, but 

 often longitudinally and transversely striated. Tentacles large and 

 stout, numerous, usually banded. Mouth large, with strongly marked 

 lobes, the stomach often everted. 



Color very variable ; column usually some shade of red or green, 

 or variously mottled and striped with these colors ; often bright red 

 and uniform flesh color. Tentacles usually banded with alternating 

 rings of white and some shade of red or pink ; sometimes uniform red 

 or flesh-color. Disk usually lighter than the column, frequently pale 

 reddish, or greenish, or mottled; usually, if not always, with radiating 

 stripes of brighter red or crimson, which extend from near the mouth 

 to and among the bases of the tentacles, two of these stripes going 

 to each tentacle and embracing its base on each side. Small white 

 spots often occur in front of the inner tentacles. The angles of the 

 mouth are usually bright red. Large specimens are often 4 to 6 inches 

 in diameter; tentacles 1 to 1"5 inches long; '20 to "25 in diameter at 

 base. 



Occurs commonly on all the northern coasts of Europe, from France* 

 northward ; Iceland; Greenland; Arctic America, southward to Cape 

 Cod. On the Pacific coast in the Arctic Ocean north of Behring's 

 Straits, in 30 fathoms, and in Behring's Straits, — North Pacific Expl. 

 Exp. ; Sitcha, — Brandt ; Puget Sound, — Dr. C. B. Kennerly. 



The numerous specimens obtained by the North Pacific Exploring 

 Expedition do not appreciably difi^er from those of the north Atlantic 

 coasts, preserved in the same manner. Nor is there anything in 

 Brandt's descriptions to indicate a specific difierence. 



A. elegantissima Brandt, is said to have the body pustulous, green- 

 ish red or spotted. Tentacles moderate, dilated, and white in the mid- 

 dle, purjile at the end. From Sitcha. 



A. Laurentii Br., has the body red, blotched irregularly with green 

 and brown. Tentacles vermilion red. Behring's Straits. 



Evactis Verrill, gen. nov. 



The column bears vertical rows of verruciform suckers or tubercles, 

 and is perforated by numerous openings from which water is ejected 

 when the body suddenly contracts. The inner tentacles are smaller 

 and shorter than the outer ones ; mouth with four prominent lobes. 

 Type Actinia artemisla Drayton. 



* The southern European form {U. coriacea) is more verrueose and may be distinct 

 from the true U. crassicornis of the north.
