is colourless. The tentacles cannot be counted exactly, their number has probably been about 120. 

 One of the specimens from St. 2066 is 26 mm. wide and badly preserved; the other specimen is much 

 larger, 42 mm. in diameter and 28 mm. in height. The manubrium is narrow, 16 mm. long, 2 mm. 

 of which form the mouth tube. The stomach has the same colour as in the specimen mentioned above, 

 though not quite as dark. Throughout the length of the stomach eight narrow, sharp lines are seen 

 opposite to the eight radial canals, and there are eight fairly broad and flat longitudinal furrows in 

 the intervening spaces. There are about 190 tentacles. The velum is 5 mm. broad. Bigelow's type 

 specimen was about 22 mm. wide with 179 tentacles, 'that is [Bigelow says] only about one-third as 

 many as in C. brunnea of about the same size '. The structure of the manubrium is quite different 

 from that in C. brunnea. 



Distribution. Bigelow described two specimens from the east coast of Japan; Uchida (19476, 

 p. 339) gives a doubtful record from the same area, in which one wrecked specimen was found. Now 

 also found in two localities off the west coast of tropical Africa .

All these stations are in the Atlantic Ocean between the Cape Verde Islands and the Cape of Good 

 Hope; the southernmost locality is St. 842, in 36° S, 13° E. 



Distribution. Generally distributed in the warm and temperate parts of all the oceans including 

 the Mediterranean. In the Atlantic it penetrates as far north as the Bay of Biscay and the Gulf of 

 Maine, in the Pacific as far as Japan and California. Its southern limit of distribution is in about 

 35° S in the Atlantic and Indian Oceans, and in about 20° S in the Pacific.
