FAUNA OF THE OUTER WESTERN AREA OF THE CHANNEL. 333 



In most cases as single specimens, and always with the species 

 Eupagurus lyridcauxi when a Pagurid was present (see p. 355). 



It is remarkable that though Eupagurus hernhardus was frequently 

 recorded, its common associate Adamsia polypus never occurred 

 (see p. 299). 



ZOANTHIDAE. 

 Epizoanthus incrustatus, Diiben and Koren. 



Two specimens were obtained at Position 43, of the carcinoecious 



form, with six and seven polyps respectively. 

 Depth, 45 fath. 



Epizoanthus couchi, Johnston ? 



At Position 15, in 44 fath., two colonies apparently of this species 

 occurred, each growing on a stone. In each case the polyps, which 

 number seven and about fifteen respectively, are partly connected by 

 a ribbon-shaped band, and partly isolated. All are strongly contracted, 

 with the height not exceeding the diameter, which ranges from 5 mm. 

 in the largest to 2 mm. in some of the young polyps. They are thickly 

 incrusted with sand. 



Epizoanthus sp. 



At Positions 7 (one) and 42 (one), in 42-44 fath., a free form of 

 Epizoanthus was obtained which rather closely resembles Holdsworth's 

 description of Zoanthus ruhi'icornis (57), and may belong to that 

 species, but the colour of the tentacles was not observed in life. The 

 first specimen consists of two polyps arising at an acute angle from a 

 common base, the largest being 15 mm. in height by 4 mm. in diameter 

 at apex. In the second specimen two polyps arise from a common 

 base at an obtuse angle, their height and greatest diameter being 

 20 mm. by 5 mm., and 9 mm. by 4 mm. respectively. 



TUKBINOLIDAE. 

 Caryophyllia smithi, Stokes. 



Recorded at Positions 7, 8, 9-13, 15, 18, 19, 33, 35, 37, 43-45, 47, 53, 



56, 58, 59, 62, 64, 80. 

 Depth, 42-53 fath. 



More than one and often several specimens occurred at each 

 position, on shells and stones ; many specimens at Position 80. The 

 barnacle Fj/rgoma anglicum was associated with individuals at 7 (one), 

 11 (one), 45 (two), and 59 (one).
