Funicnlina quadrangularis, Pallas. 



In the summer of 1895, at Salbuskallen on Herlofjord, Dr. 

 Appellof found a very interesting young luniculina quadrangularis, 

 which seems to be the most nearly-allied of the hitherto known 

 early stages of this Penna tulid, to the previously described 97 mm. 

 long specimen from the Bergen Fjord ( x ) and the 152.5 mm. long 

 specimen described by Kollikee, from the „Porcupine" Expedition 

 in 1870 (or 1869). ( 2 ) 



The specimen, which was entire and uninjured, was of the 

 following dimensions: 



Total length 175 mm. 



Length of stalk 35 mm. 



„ rachis 140 



Diameter of stalk 0.4 — 0.6 



95 



11 



„ „ rachis 0.3 „ 



The bulb is only slightly thicker than the stalk, and both are 

 round; the rachis, on the contrary, is quadrilateral, and rounded 

 only in the upper part. In its lower part, it is of the same width 

 as the stalk, but tapers gradually towards the apex, where the dia- 

 meter is about 0.2 mm. The proportion of the stalk to the rachis 

 is as 1 : 4.

( 2 ) This specimen, which, according to Kolliker, was found on the „Por- 

 cupine" Expedition in 1870, in 48° 26' K Lat. and 9° 44' W. Long., at a depth 

 ot 358 fathoms (Stat. 6), must be identical with the specimen mentioned by 

 Milnes Marshall and Fowler in ; ,Pennatulida dredged by H. M. S. 'Porcupine'" 

 (Transac. Roy. Soc. Edinburgh, Vol. XXXIII, p. 460), tåken at Station 54, in 

 1869 (59° 36' N. Lat., 6° 27' W. Long., depth 363 fathoms). According to these 

 authors, Station 54 is the only station where iuniculina quadrangularis was 

 found during the „Porcupine's" cruises in 1869 and 1870: only Pennatula phos- 

 phorea was tåken at Stat. 6.
