Haddon — Note on Halcampa chrysanthelhim, Peach. 5 



fourth ; and the first white ring surrounding the foot is sometimes 

 tinged with sulphur -yellow." 



The description of the specimens dredged by Sars, in twenty 

 fathoms, at Ure, Lofoden Island, and also at Bergen, agrees so 

 closely with some of the Malahide forms that there can be little 

 doubt as to their identity. He describes the body as cylindrical, 

 white ; hyaline, with a brown epidermis ; tentacles twelve, white ; 

 hyaline, with two brown rings ; twelve brown spots round the 

 mouth. The shape of tentacles and other points are identical in 

 the two forms. The brown " epidermis " probably refers to the 

 slimy sheath being beset with sand or other foreign particles. 



The careful account of Meyer and Mobius leaves no doubt con- 

 cerning the identity of their specimens with Peach's. They state 

 that the body is smooth, flesh-coloured, with pale longitudinal 

 lines; it generally covers itself with a tube of slime and sand 

 grains. The tentacles are quite colourless, with two or three red- 

 dish-brown transverse bands, and similar longitudinal stripes at 

 their bases ; there are brown spots on the disc, each corresponding 

 with the tentacle. 



The authors refer to the extreme transparency of the dilated 

 body, and to the presence of a pair of fine lines in the alternate 

 broad red bands of the body, referring, of course, to the small 

 secondary mesenteries (fig. 4, p. 12), and of which they give (pi. in., 

 fig. C) a characteristic drawing. They found eight to eleven ten- 

 tacles in their forms — length, 20-25 mm. ; diameter, 2-3 mm. 

 In mud, Bay of Kiel, 6-9 fathoms. They further identify with 

 this species the two specimens found by Dr. Lutken, at Helleback 

 in the Sound; but Andres (/. c, p. 96), considers this a true 

 Edwardsia, which he names E. lutkeni. 



Dr. Andres correctly placed Sars' species in the genus Hal- 

 campa ; but he believed that it was identical, save for characters 

 " of the smallest importance," with Halcampa farinacea, Verrill, 

 and, " rather than preserve a record of the two species," he unites 

 them into one. Whether YerrilFs species is identical with any 

 European form is very doubtful, and the evidence would seem to 

 point the other way : for the present, at all events, his name must 

 stand. 



The great range of variation of M. chrysanthelhim suggests a 

 critical examination of the two species which Keferstein described
