1 5 PENNATULIDA. 



have no information at all as to the place where the specimen was found. Esper's Pennatula alba 

 which Kolliker has referred to his var. angustifolia^ closely resembles, to judge from the figure, 22, 

 pi. VI, the specimens in hand from the Vestman-Islands; their colour is said to pass almost impercep- 

 tibly into a reddish one; but we have no information as to the place where these specimens of Esper 

 were found. 



Verrill mentions a white specimen of Pc7inahila aculeata (Amer. Journ. Sc, vol.23, P- 3io> ^"^^ 

 Report... Blake p. 3) taken by the Fish-Hawk; at st. 1025, depths 216 fathoms; he says of it: «This 

 is doubtless only an albino» ; it appears to have been taken together with numerous specimens of the 

 common red form of Pcnn. aculeata (comp. Am. J. Sc. 23, p. 315). 



Remarks. According to what has hitherto been known, it must be regarded as hardly pro- 

 bable that Pennatula phosphorea should be found outside the Atlantic. Studer, however, in his preli- 

 minary report of the «Albatross> Expedition (p. 55) has given Penn. phosphorea as from the Pacific, from 

 0° 19' N. LaL 90° 34' W. Long., 331 fathoms, and /.Pennatula distorta, Dan. Kor, var. pacifica, n. var.», 

 from 1° 7' N. Lat. 81° 4' W. Long. Of the former, it is said that the (single) specimen was not to be 

 distinguished from the Atlantic (i. e. the typical) phosphorea L. As to Penn. distorta Kor. and Dan., 

 this species cannot be maintained, in my opinion; it is nothing but Penn. phosphorea with unusually 

 narrow and (casually?) distorted wings; and the Penn. distorta var. aculeata described by the same 

 authors, is obviously only ^distorted specimens of the .species Pcnn. aculeata. And with regard to 

 Studer's iPenn. distorta, pacifica<>^ his remark that the colour is whitish yellow, and that the calyx- 

 spicules appear to be longer and more conspicuous, seems to me to indicate that another species must 

 be in question; from the Asiatic side of the Pacific several /',?«Ma/!?</«-species are known, among others 

 just such forms with narrow leaves in which yellow or reddish yellow is prevalent in the colour, and 

 where the type of spicules, moreover, is different from that oi phosphorea; also the depth, 1740 fathoms, 

 must be regarded as somewhat great for the supposed species. Th. M or off (Zool. Anzeiger 1902, 

 p. 579, and Zool. Jahrb. Abth. Syst. 17 Bd., 1902, p. 380) has established a P. phosphorea var. longispinosa 

 from Japan (i specimen); unfortunately, his figures show onl\- that the specimen is a Pe7i7iatjila\ but 

 some remarks in the description would indicate that phosphorea is not in question (for instance the 

 broad streak between the «ventral» zooids).

This splendid species has not been taken by the «Ingolf» itself; but during one of our sojourns 

 at Thorshavn I received from Mr. Finsen, apothecary, a specimen taken on «the bank south west 

 of the Faeroe Isles at a depth of 90 fathoms»; later, 19 specimens from the Faeroe Isles have been 

 sent to our Museum by the agent Mr. Muller, taken on the fishing bank east of Fuglo, ca. 150 

 fathoms. With the exception of one individual (Nr. 20) all the specimens are large and well-developed. 



I can add nothing essentially new to the former descriptions (by Sars, K5iliker, Koren & Danielssen,
