Krauss speaks of the zoarium being " bleifitrbig und dunkelgraue " ; 

 Macgillivray says greenish or leaden colour ; Busk says " ovicell blue " (but 

 did he not mean to refer to the zoarium ?) ; Kirkpatrick says " the zoarium 

 is of a leaden-blue colour " ; Miss Philipps, in her Loyalty Island paper, 

 says " zoarium leaden-blue " ; and Miss Thornely, in her Indian Ocean paper, 

 says " ovicells not blue " ; Calvet did not find any colour, but says that the 

 specimen had been many years in spirit. No one, however, seems to have 

 noticed the curious fact that the polypides and growing tissue are blue, 

 looking just as if they had been stained, and in these Cape Verde Islands 

 specimens it is a fairly bright blue. The specimens left in spirit have 

 lost their colour, and one set of spirit-specimens were always without colour. 

 A spectroscopic examination of this species would surely be interesting 



The geographical range is very great, occurring in many places from 

 Japan to the Cape Verde Islands. 



There are about 14 tentacles.

There are some specimens closely attached to Adeonella contorta, Mich., 

 with the creeping growth and attachment by radicles, as known in 

 S. reptans (Linn.), Cray. On account of the resemblance of the two species 

 I at one time spoke of S. reptans, var. Bertliolletii. 



There are some very large erect median avicularia, much larger than I 

 have seen in any other specimens of »S. Bertliolletii. Hincks has mentioned
