138 ZOOPHYTES. 



Animal a low depressed rounded cone, 1| inches broad, sides smooth, 

 vertically lined with brown; tentacles 24, in 2 series, 6 to 8 lines 

 long, rather stout ; disk small, radiated with whitish lines ; mouth 

 small, circular, not prominent.

The diameter of this species is sometimes one and a half inches, 

 though rarely found over half an inch. The body becomes nearly 

 flat on contraction. Colour a pale ochre, on which are disposed a 

 number of longitudinal lines of an amber colour, and arranged in 

 regular order, a broader one alternating with two narrower, so as 

 to leave between each of the broader lines, three ochreous ones of 

 the same width. Near the inferior margin, the colours are fainter, 

 giving it the aspect of being surrounded by an indistinct zone. The 

 tentacles have a pale flesh colour. The disk is purplish-brown, with 

 flesh-coloured lines extending from base of tentacles to near the centre, 

 of a pale ochre colour. Mouth retaining a circular form, even in con- 

 traction, with convex ridges on its margin, which correspond to the 

 tentacles. The tentacles of this species were constantly and very 

 actively in motion, and it shifted its position much more frequently 

 than usual, gliding readily over the smooth surface of the jar in which 

 it was kept, by the contractions and expansions of its base. 



The young were observed in several instances to be ejected from 

 the mouth. They were at first attached to the parent by a white 

 filiform pedicel, about a quarter of an inch long, which appeared like 

 an extension of the base. In about five minutes after the expulsion, 

 they separated with the pedicel still attached : shortly after, it gradu- 

 ally contracted, disappeared, and in a quarter of an hour they attached 

 themselves to the bottom, and fully expanded. They resembled the 

 parent, but were paler and more transparent. J. P. COUTHOUY.
