among the ventral zooids, another large bud, which is, however, 

 rather smaller than the first-named one. From its position, the 

 ventral bud must correspond to what I have previously called the 

 3rd sexual polyp. The large lateral bud must, on the other hand be 

 the 4th sexual polyp, which has accordingh, in this specimen, developed 

 earlier, or at any rate more quickly than the 3rd polyp. Below 

 these two buds are found, among the lateral zooids, other large 

 buds, which will probably develope into polyps. 



In addition to the terminal zooid, this specimen has 4 rows of 

 lateral zooids, two on each side of the naked, dorsal, median part. 

 Furthermore, between the terminal zooid, and the terminal polyp, 

 there are some top-zooids, ^cheitelzooiden 4 '. Lastly, on the ven- 

 tral side, between the polyps, there are two rows of zooids running 

 from the head zooids. 



Of all the stages previously described, this specimen most 

 nearly resembles the 47 mm. long Kophobelemnon abyssorum from 

 Korsfjord. It is, however, distinguished from that specimen by its 

 two rows of ventral zooids, the Korsfjord one having only a single 

 row. 



The specimen from the Trondhjem Fjord, which unfortunately 

 was damaged, has 4 fully-developed polyps. Of these the Ist sexual 

 polyp is situated to the left, the 2nd to the right of the terminal 

 polyp, and the 3rd ventrally be]ow it. Below these, there are yet 

 other larger buds, incipient polyps. There is the terminal zooid, 

 4 rows of lateral zooids, some top-zooids and some ventral ones. 

 As, however, the coenosarc on the rachis was drawn down over the 

 axis, as a result of the injury, so that it was free for a length of 

 7 mm., the arrangement of the ventral zooids cannot be more mi- 

 nutely described. 



Lastly we have the 47 mm. long specimen with 6 polyps, of 

 which the lower three are quite small, but with w ell- developed ten- 

 tacles. The terminal polyp is 3 mm. below the terminal zooid, 

 To the left of this polyp, there is, as usual, the Ist sexual polyp; 

 the 2nd is situated to the right, and the 3rd ventrally below the 

 terminal polyp. The 4d sexual polyp is to the left of it, and rather 

 lower than the 3rd; the 5th polyp, on the other hand, is to the 

 right. The polyps here are arranged in the manner pointed out 

 by Milnbs Maeshall, (*) namely, in two sets of 3, one of which
