Female and male gonophores on their gonostyles and gonopalpons are present in all 

 stages of development. 



Cat. 21 s J (PI. X, fig. 83) is a specimen which through contraction has lost more of its 

 appendages than those of Stat. 165. It resembles therefore in this respect more the Forskalia 

 contorta of the Siboga material. It shows again how Forskalia changes through preservation. 



Some specimens of Forskalidae were entirely unrecognizable through the absence of the 

 most necessary appendages. 



They belong to : 



Stat. 136. Ternate-anchorage. Cat. 71 CD. E.G. ale. 9o7o- 4 specimens. 

 Stat. 186. Lat. 3°io'.5S., Long. i27°2o'.5E. CaA 25 U. One .specimen. 

 Stat. 189'. Lat. 2°22'S., Long. 126° 46' E. Cat. 127 E. ale. 9o7o- One siphon. 

 Stat. 205. Lohio-bay, Buton-strait. Cat. 50 A. ale. 9o7o- One specimen. 



Erenna Bedot. 

 42. Erc7ina Bcdoti nov. spec. PL XI, figg. 85 — 90. 



Maurice Bedot describes in his "Siphonophores provenant des campagnes du yacht 

 "Princesse Alice (Monaco 1904)" tentacles of a Siphonophore apparently unknown up to that 

 date which he called Erenna Richardi. The fragments he found are not sufficient to his opinion 

 to give Eremia a definite place in the system but he thinks it not improbable it belongs to the 

 order Physophora (Physonecta). We found in the Siboga material a specimen which possesses 

 tentacles resembling those of Erenna Richardi. W^e therefore called this onl\' specimen Erenna^ 

 using a new specific denomination "■ Bedoti' as of course we cannot decide whether the tentacles 

 described by Bedot belonged to a specimen entirely identical with ours. 



Provisionally we place Erenna with the Forskalidae. 



The sketch of the whole specimen (PI. XI, figg. 85, 86) is perhaps somewhat difficult 

 to understand. We found first of all that the nectostem with its pneumatophore and buds of 

 nectophores, had broken off from the siphosome. It surely belongs to the same specimen and 

 we suppose therefore the lower part of the nectosome a (PI. XI, fig. 85) to have been attached 

 to a (PI. XI, fig. 86) in the siphosome. 



The pneumatophore (PI. XI, fig. 85) has a length of 4,5 mm., a breadth of 2,5 mm. 

 It is transparent, shows a small brownish-red pigment-cap at the top and 8 longitudinal white 

 stripes. Its colour is whitish, the stripes are opaque white. In the immediate neighbourhood on 

 a muscular elevation of the nectostem are imbedded eighteen buds of nectophores in different 

 stages of development. They are very particularly characterized through the presence of black 

 granulations which follow (or are contained in ?) the radial and circular canals. Of the largest 

 of these nectophores we give a sketch (PI. XI, fig. 87). The substance of the nectophore is 

 opaque greyish-white; the black stripes are particularly clear in the two median longitudinal 

 lines and in the basal part of the nectosac, where the line following the side parts of the 

 nectosac sends on both sides a short canal which stops abruptly. These black granulations are 

 also to be found in other appendages, of which we will speak later and they constitute one 

 of the characteristics of Eren7ia. They have never been described in other Siphonophores.
