,Nr. 39. Campanulai'ia sp. 

 (Inaba, Kishu Hydroids 1892a Fig. 1, 2. 3; Misaki Hydroids Addenda 1892c Fig. 3, 4, 5.) 



Tropiiosonie. Sterns very slender, growing in mimbers from a creeping hydrorhiza. 

 without branclies, twisted, only 2 or 3 mm higli, witli a hydranth at the end. liydrotheca 

 bell-shaped, margin straight and thin, as il' it were cut away on tlie outside. 



Gonosome. Gouotliecae growing crowded on the hydrorhiza, with very short stalk, 

 somewhat flattened, wide above and narrow below, upper edge straight as if it were cut oflf. 



Colour. Periderm transparent and colourless, hydranth light red. 



Locality. Shimotsu-ura, West Coast of Kishu, about 2 m deep, on basal part of Sar- 

 gassum. — Also coUectedat Misaki, Sagami Sea, in April, attached to Sertularia, Eudendrium etc., 

 with reproductive organs. Compared with the specimens from Kishu, the stems are longer; 

 the reproductive organs are also smaller, possibly because the Misaki specimens are young. 

 Compare the figures 1892a figs. 1 — 3 [hier Fig. 30 — 31]. 



This species is very similar in general appearance to Nr. 13 [Clytia delicatula (Thornely)] 

 and was at first thought to be identical with it, but a closer examinatioa has revealed 

 their difference. The characters of the reproductive bodies leave no doubt as to its be- 

 longing to the genus Campanularia. Species of this genus ought to be tolerably common, 

 but none have so far been found in Misaki, so that this is the tirst species of the genus 

 that has come under my Observation. 



The reproductive bodies are unusually large, and are as high as the total length of 

 the stalked hydrotheca, as shown in the figure. The egg-cells are disposed in two groups 

 and are contained in the gonotheca. To all appearance the cells of one of the groups ripen 

 first and are gradually extruded, after which those of the other groups go in turn through 

 the same process." (Inaba 1892 a, 1892 c.) 



,Nr. 40. Campanularia sp. 

 (Inaba, Kishu Hydroids 1892 a Fig. 4, 5.) 



Trophosome. Stems slender, 5 mm higli, growing in numbers from a creeping hydro- 

 rhiza, twisted slightly, with a hydrotheca at the end. Hydrotheca bowl-shaped, the dia- 

 meter of the mouth surpassing its depth, margin straight and thin as if cut off from within. 



Gonosome. Unknown. 



Colour. Perisarc yellowish brown; hydranth yellowish brown. 



This species is only provisionally referred to Campanularia, owing to the absence of 

 the reproductive bodies. It is very closely similar to the preceding species and was thought 

 to be possibly identical with it, but detailed examination has led me to make a different 

 species of it. Generally speaking, it is somewhat larger than the preceding species, with 

 a thicker perisarc of a brown colour. Moreover the hydrotheca is bowl-shaped and rarely 

 bell-shaped as in the foregoing species. It grows luxuriantly and has been found in many 

 localities." (Inaba 1892 a.)
