,Nr. 24. Plumularia sp. (Inaba 1890 Fig. 65, 66, 67, 68.) 



Trophosome. Stern streng and large, consisting of a bündle of smaller tubes, with 

 many irregulär branches, the terminal steni.s coniposed of inore or less irregulär joints, 

 each Joint giving out one or tvvo regularly alternate branches. Each brauch consists of 

 regulär joints, each with one hydrotheca, which is small, deep, bowl-shaped and expanded 

 in the upper part, with a large, upwardly projecting, sharp tooth on either side of the 

 mouth. Nematophores slender and elongated, 1 pair above and behind the hydrotheca, 

 and 1 niore directly below it in front. The arrangement of the nematophores on the 

 stem is not very regulär. On a shorter Joint carrying but one branch, there are usually 

 2 side by side at the lower end, 2 in the lower part and 1 at the upper end; on 

 a longer Joint carrying two branches, there are usually 8, a pair at the upper and at 

 the lower end, 1 pair between, and a couple more near the base of the branch. 



Gonosome. Unknown. 



Colour. Deep yellowish brown. 



Locality. Shishigahana, Sagami Sea, about 5 m. 



This species is very large, reaching the height of 300 mm, very strong. There are 

 generally no branches in the lower part of the stem, the whole simulating the form of a 

 Cryptomeria. The genus Plumularia has usually a delicate perisarc, and the edge of the 

 hydrotheca is straight; but in this species there are 2 large teeth on the border of the 

 mouth, the perisarc is considerably thickened, features rarely seen in the genus. Collected 

 in December; there are no reproductive organs.' (Inaba 1890.)
