strai*Tht across the eelatinous substance and it is clear that the branches are ever so much 

 more ventral than the actual body of the phj-llocyst (see PI. I, Iilj. 4). The dorsal side of the 

 phyllocyst is convex. Distally it narrows suddenly and ends in a club-shaped narrow tube going 

 straight up to the dorsal side of the bract. 



Some of these phyllocysts end in a very narrow more thread-like canal (PI. I, fig. 4). 

 Unfortunately there is no complete specimen well preserved enough to show the point where 

 the siphon is in connection with the phyllocyst. 



The three complete specimens have, unluckily, been preserved very badly. There were 

 gonocalyces but it is impossible to give any description at all of them. Only one is not too 

 unworthy of sketching and this can be said only of the distal part. A sketch of this very imperfect 

 part of Cei'atocyinda asyuimetrica might perhaps be of some use for later researches (PI. I, fig. 5). 



Bedot was luckier in this case as he gives a sketch (1904 fig. i) of a female gonocaly.x. 

 The distal part somehow shows some differences, as it seems that the posterior ventral teeth 

 differ in length whilst this does not occur in our specimen.

A single nectophore-like structure, resembling an upper nectophore of a Diphyid or one 

 of a JMonophyid such as Chun described (92) was found to be absolutely different from any 

 other Siphonophore described up to this date. 



Its length from top to base is 23 mm. and its greatest breadth 13 mm. The outer 

 surface is smooth, its gelatinous substance very soft, such as the jelly in Monophycs and in 

 Prayidae. There are two ridges only, but these too are without sharp edges. 



This is one of the reasons why we called it Clausophyes, after Claus the founder of 

 the family Moiiophyidac (74). 



W'e shall see furtheron in which respects it may be perhaps a Monophyid, though we 

 cannot find any decisive characteristic and we have provisionally to place Clattsophyes next to 

 another doubtful and incomplete new genus. 



Clattsophyes is of a pyramidal structure, its top being obtuse; it has no definite ridges 

 (except the two ventral ones) (PI. I, fig. 7). It is rounded exteriorly, compressed laterally. ( )n 

 the dorsal side there is a groove which is most prominent at that side (PI. I, fig. 6) and follows 

 laterally the lines of the nectosac. This looses itself very gradually in the gelatinous substance. 



There is a very distinct aperture at the base and anteriorly the contours of a nectosac 

 are seen c|uite clearly through the jelly. Nothing has been preserved of its wall, but we are 

 quite justified in identifying this campanulate structure with a nectosac. It seems as if on the 

 dorsal side of this new specimen the nectosac approaches quite closely to the outer surface 

 (PI. I, \\\^. 6). On the ventral side the contours have become very indistinct and there is no 

 possibility of ascertaining its precise outline. 



The aperture is elongated tliere where in more natural conditions the velum would have
