and is also very muscular. A further peculiarity in the structure of these palpons is the appearance 

 of black granulations near the top which is clearly indicated in all palpons ; it is not clear to 

 us whether we have here the same granulations as in the buds of nectophores. We thought 

 it better not to make any sections having had the experience when making sections of the 

 tentilla that the tissues in this specimen are entirely destroyed and as only very few palpons 

 remain, we left the specimen as we received it. 



In some gonopalpons (in /) we found moreover a kind of black string-like structure in 

 the interior second part. In this case the gonopalpon shows division into three distinct parts, 

 the pedicle, the middle part and the apex. 



The other palpons sometimes show no division at all, sometimes only one constriction. 

 This shows that the constriction is probably only a momentary muscular contraction. 



The black string-like structure seems to us to represent also an accumulation of black 

 granulations. It is not clearly indicated in the sketch, this palpon not being quite transparent 

 and the granulations being situated nearer to the opposite wall of the gonopalpon. 



The gonostyle with its only palpon r/ is opposite to the gonostyle which possesses the 

 three gonopalpons i, 2, 3 of which we have spoken and at a distance of 3 mm. 



Not only does the nectosome show muscular elevations, where nectophores have been 

 attached to it. We find the same in the siphosome and as they are very numerous, the appendages 

 as far as they are not lost, seem sometimes to stand more or less opposite to each other. 

 We suppose however that the siphosome whose muscles are immensely developed, is very much 

 contracted and that in the living state the stem certainly attained a much greater length. 



The appendages which follow now are so irregularly scattered along the stem, that we 

 cannot assign a definite place to them. We will therefore only mention them indicating also 

 those which are not drawn on PI. XI, fig. 86 as they are situated behind the appendages drawn 

 on that figure. 



First of all we find a great amount of small blackish gynophores which are probably 

 the remaining ova of gonodendra in which the older gynophores have already detached 

 themselves from the gonostyle. In front of them are attached four young undeveloped 

 foliaceous bracts. Then comes another gonodendron with young gonophores to which only one 

 gonopalpon is attached. Underneath the four buds of bracts we find a siphon, or only part 

 of one, the proximal parts having been lost, and also the basal one remaining attached with 

 its broad base to a prominence of the siphosome, which being very short can hardly be 

 said to be a peduncle. This basal part has a strongly muscular wall, somewhat contracted and 

 sh(jws interiorly a great quantity of black -coloured hepatic villi, which through the contraction 

 of the outer wall do not show any regular disposition. Situated immediately next to this 

 siphon we find an immensely broad tentacle (/"), of which also the basal part has remained. 

 This tentacle reminds one exactly of the tentacle described by Bedot and figured on fig. i 

 and 6 1904. It is, as in Ereitna Richardi, divided into segments and shows circular incisions 

 at regular intervals, the whole connected by a thin membrane, the "crcte longitudinale". In 

 our specimen the incisions show perhaps less clearly but the tentacle is very much contracted 

 and swollen; it shows two sj)iral windings and at its base ojjposite the side which was drawn,
