Haddon and Shackleton — A Revision of the British Actinia?. 661 



42, in two rows, the inner row corresponding in position to the marginal teeth, 

 the outer intermediate ; sub-equal, conical, pointed, usually radiating horizontally. 

 Coeuenchyme band-like, often bearing three polyps abreast, loosely invested with 

 coarse sand. 



Colour. — Column dull uniform olive, each intersulcus having a blackish spot 

 near its summit ; each tooth is silvery white. Disc olive-yellow ; tentacles 

 colourless, transparent, with yellow-brown pigment granules. 



Dimensions. — Column about 3 mm. high, and about 2 mm. wide. 



Locality. — Torbay, on rock, between tidemarks. 



Hincks (I.e., p. 364) says: — "Mr. Gosse mentions a single colony of this 

 pretty but very minute species as having occurred to him at Broadsands, near 

 Brickham, on sandstone rock. On the opposite side of Torbay, however, and very 

 close to Torquay, I have found it abundantly in the small basins hollowed out in 

 the limestone. The Zoanthus forms little colonies on the floor of these miniature 

 pools ; but they may readily be passed over as tufts of some minute weed." Mr. G. 

 Y. Dixon informs us that he has carefully hunted over the rock where Grosse 

 obtained his original specimens, without being able to re-discover this species. 



Fischer (1874, p. 236) describes this species as follows: — " Column covered in 

 its superior half with very fine and agglutinated sand, uniformly brownish or 

 olive, with 22 rays or ridges, on which one sees grains of sand arranged in ver- 

 tical lines. The superior border of the column is indicated by a dentate border ; 

 the teeth are 11 in number, and their colour is white. The disc of the same colour 

 as the column appears rayed. The tentacles to the number of 22 are arranged in two 

 rows ; the 11 tentacles of the inner row are longer than the marginal by a third or 

 a fourth. They are conical, transparent, ornamented with some brown spots ; 

 their extremities have an opaque white colour. The yellow mouth is not 

 prominent." 



" I have found this species at the landing place of Arcachon, at the limit of low 

 tide ; it forms very numerous colonies, which have an appearance of the perforating 

 sponges (Cliona), but their colour is more pronounced. The colony is fixed upon 

 an expansion thickened by sand and other adherent matter. This is perforated by 

 circular holes for the emission of the Zoantheae, which sink in and disappear when 

 they are disturbed. M. Lafont has met with this species at Gu^thary, on rocks. 



" The figure given by Mr. Gosse is very bad. . . . The small size, the colour, 

 the habitat of this species, readily distinguish it from the preceding [K couchii']. 

 When it is extended it measures 4 mm. in diameter." It occurs between tides 

 (littoral zone), p. 239. The other Paj)ers are merely abstracts. 



Later (1887), Fischer gives the following French localities: — " Le Croisic, 

 Piriac (E^gion armoricaine) ; Arcachon, Gu^thary, (Region aquitanique) ; Zone 

 littorale," p. 435.
