small and bears near its base a quantity of thread-like, tubular tentilla. There are no younger 

 siphons than this last one. 



The palpons are elongate, cylindrical, not quite transparent but more whitish opaque. They 

 are scattered irregularly on the stem. Not one palpacle was found, we suppose they became 

 detached when the specimen was captured. 



Of bracts there were only two left. They are situated in the open space, where a 

 siphon had become detached. One, the largest in size, has undergone complete alteration and 

 has become shapeless, the other is smaller and has a length of 5 mm. It is absolutely flattened 

 (PI. XVI, fig. 119) and has a foliate appearance, two small incisions occur on both .sides, which 

 even on the right side attain the appearance of a lobe. 



The canal in the bract goes throughout the gelatinous substance; it is cylindrical near 

 its base and gets more and more pointed towards its apex. On the dorsal side of the bract, 

 two oval structures are to be seen, the right being somewhat smaller than the left. They are 

 situated in the centre of the bract, and on the left and right .sides of the canal. They seem to 

 consist of granules imbedded in a cavity of the gelatinous substance. From both these (?) glands 

 microscopically small threads issue. The right small canal goes down and meets the canal of 

 the left gland which has its course straight over the main canal of the bract. They then lose 

 themselves very soon in the gelatinous substance and no further trace can be seen of them. 

 Owing to the granular interior structure we rather incline to think they are agglomerations of 

 pigment which through preservation have lost their colour. 



At any rate these structures do not resemble the glands we found in Crystallomia spec. 

 (p. 77) nor those which Bedot described 95 in Stcphanopsis Clausi. The gonophores are also 

 present, they are irregularly scattered on the stem, so that one gonodendron consisting chiefly 

 of undeveloped gynophores seems to be situated on the dorsal side of the stem. We counted 

 three 9 gonodendra ; andro]jhores were not found.
