70 MR JAMES ETTCHIE : SUPPLEMENTARY REPORT ON 



One specimen was found " on the surface of the water, in a hole which had been cut in 

 the ice. The depth of the water at that place was 20 to 30 fathoms ; the temperature 

 was 29° F." 



M. austro-georgice has previously been recorded from Cumberland, South Georgia, 

 (Jaderholm), and from Flanders Bay and Booth- Wandel Island (Billard). 



Eudendrium annulatum (?), Norman, 1864. 



Two small clumps of bushy colonies appear to belong to this species, but the' 

 weathering of our specimens, and the indefiniteness of the characters which differentiate 

 the species of Eudendrium, render certainty impossible. The colonies are 5 cm. high, 

 and agree with Canon Norman's species in being bushy and beset with very numerous 

 branchlets ; in possessing thick, rugged stems, on the surface of which, near the base, 

 the fascicular tubes are more or less contorted ; in having branches closely covered with 

 strongly marked rings ; and in bearing hydranths with about from 16 to 18 tentacles. 

 On the other hand the gonophores, all of which are female, are borne on tentacle- 

 bearing hydranths and not on atrophied individuals. So many, however, are the 

 gonophores and so closely are they packed around the hydranth, that in not a few cases 

 it was difficult to distinguish the presence of tentacles. Since, in some species at least, 

 the loss of the tentacles is a degenerative change keeping pace with advancing maturity, 

 their presence in this case may be of less significance than at first one tends to regard it. 



These measurements were made : — The diameter of the unfascicled branches and 

 branchlets is almost constant, about 0*18 mm. The hydranths are about twice as long 

 as broad, the breadth being measured at the level of the bases of the tentacles (0'57 mm. 

 long, 0*28 mm. broad). 



Locality. — Entrance to Saldanha Bay, Cape Colony. Depth, 25 fathoms. 21st May 

 1904. 



Eudendrium annulatum is a North Atlantic form which has been recorded from 

 Shetland (Norman, 1864); Jan Mayen (Marktanner-Turneretscher, 1890) ; Pas-de- 

 Calais (Betencourt, 1899) ; Norwegian Coast (Bonnevie, 1899). 



Perigonimus repens (??) (Wright, 1858). 



Scanty material which I have, not without doubt, referred to the above species was 

 collected on the shore at Port Stanley. The stems, with a diameter of from , 04 to 

 0"05 mm., arise from a stolon creeping upon an encrusting Polyzoon, and reach a height 

 of 10 mm. They bear a considerable number of branches which leave the stem at a 

 sharp angle and carry secondary, and these sometimes twigs of tertiary degree, in such 

 ,i way as to give the colonies the appearance of being dichotomously branched. The 

 otlslioots can always be distinguished, however, by the presence of a slight constriction 

 at their bases. The stems bear distinct rings at their bases and here and there through-
