flattened out and mnch and variably extended in all directions, the 

 edges crenulated by the insertion of the mesenteries, of -svhich there 

 are about 100; when dead the base is withdi'awn. Capitulum short, 

 crenulated, invisible when the animal is fully extended; when re- 

 tracted it almost completely covers over the tentacles. Tentacles 

 short, conical, tetracyclic, 48 in number (6 + 6 + 12 + 24). Disc per- 

 fectly flat. Mouth, with fairly prominent lips, round. The body was 

 entirely covered with graias of sand and broken shells. Coloui' — 

 base translucent buif ; scapus flesh-coloured ; capitulum translu- 

 cent pink ; the mesenteries of the primary cycle of tentacles marked 

 by a pair of dead-madder triangular spots; the three iatervening lobes 

 having a pale yellow spot. Tentacles pale, with two rows of pale- 

 brown spots. Disc dark sepia, with six pairs of radial cream-coloured 

 lines, and six shorter pairs for the secondary tentacles, and with simi- 

 larly-coloured spots in rows between the liaes. Mouth deep madder- 

 brown ; lips paler. Diameter of base 21-25 mm. ; diameter of scapus 

 12 mm. ; diameter of disc 7 mm. Only one specimen of this remark- 

 able anemone was dredged. It has some resemblance to Chitonactis 

 coronata, Gosse (cf. Actinolog. Brit., p. 202, pi. vii., fig. 4, and 

 Fischer, Nouv. Arch. Mus., x., 1875, p. 193), but differs in the 

 absence of tubercles, and in many other characters. Marion, in the 

 Paper alluded to above, records, but not describes, C. richardi, sp. n., 

 var. A., on branches of Mopsea elongata, and var. B. free on mud, from 

 the Bay of Biscay; and it is unsatisfactorily figured on pi. vii. of 

 Filhol's La Vie au Fond des Mers, but no mention of it is made in 

 the text. It is with considerable doubt that our species is rele- 

 gated to the genus Chitonactis. 



The family Zoanthidee was represented by a few forms, but our 

 knowledge of these creeping colonial Actinise is at present in such an 

 unsatisfactory condition, that it is almost impossible to identify them 

 with any degree of certainty. Palythoa arenacea (?) D. Ch., Stations 

 I. to XII. and Berehaven, 10 fathoms. P. sp., a squat button-like 

 form from last locality and Station I. Epizoanthus papillosus, Johnst., 

 an erect species entirely encrusting shells inhabited by Spiropagurus 

 laevis, Thomps., and Eupagurus excavatus, Herbst, three specimens 

 from Station I. 



Hexacoeilla. 



The very few corals obtained mostly belong to the genus Caryo- 

 phyllia, C. clavus, Scacchi, var. borealis. Dune, Stations I. and III. 

 C. clavus, var. smithii, Stokes and Brod., Stations III., YIL, XII. 

 A worn and broken colony of C. cylindiica, Eeuss, occurred at Sta- 

 tion III. in 40 fathoms. Three specimens of Sphenotrochus wrightii, 

 Gosse, were found in Berehaven ; these are, undoubtedly, fresh speci- 

 mens (cf. Gosse, Actinologia Britannica, p. 326).
