rest of the jelly; macroscopically they show distinct brownish-coloured outlines. At first sight 

 they resemble in structure the lines which are to be seen along the ridges of Abyla basscnsis" 

 superior and inferior nectophores. 



To give a better idea of the position of all these ridges we made sketches of the 

 different facets.

The p}-ramid consists at the apex of four ridges. To distinguish them we call the dorsal 

 one a' ^ the right lateral one «^^, the left lateral one a^^^, the ventral one a'^'. These devide 

 themselves (about 5 mm. from the top) each on the same height as the others into two, and 

 in this way there are soon eight ridges and eight facets. Some of them (see furtheron) are 

 microscopically very delicately serrated. 



We begin with the two ridges, which arise from the principal dorsal one (textfig. 12). 

 We call the ridge on the right side a, on the left side a . All the accents are given to the ridges 

 on the left side of the nectophore, the facets bear the capital letters A, A', B, B', C, C, D, D'. 



Facet A (textfig. 1 2), the most proximally situated facet, consists of the ridges a and a' 

 and is elongated; at its base is ridge e. The side-ridges [a and a') are about 6 times longer 

 than e. Ridge e is straight. The shape of facet A is elongated triangular. On the right and 

 left side of facet A are facet B and B'. They consist (te.xtfigg. 13, 14) of 5 ridges each, «, a', 

 a"^ b and / for facet B and a , a', a^'' and ridge /' for facet B'. 



As a and b (and a and b') differ in length at the base, it follows that ridge / (resp. /') 

 has an oblique course. 



The facets B and B' do not differ from each other but of course they are not of the 

 same shape as A', because they are the intermediate facets between the original four ridges; 

 they continue to the top of the nectophore. 



Facet C and C (textfigg. 15, 16) are three-sided again as facet A is and consist resp. 

 of ridges b, c and g and b\ c' and g' . 



The ridges g and g' are strangely divided into two again and form a line bearing a 

 resemblance to the letter Z. 



The facet D and D' (textfigg. 17, 18) consist of the junction of a^^' with ridge c on 

 the right side and of a'^^ and c' on the left side. Most ventrally the ridge a'^' is the one which 

 connects, partially D and D'. But distally «'''' divides itself into d and d' . This unison of two
