left lateral mesenteries, and the large funnels to the right ventral 

 mesentery. This may be the common case, but the single spec- 

 imen at hand has large and small funnels among each others. The 

 specimens at hand of pisanii Ludwig have, besides the normal 

 funnels, some small long-stalked funnel-like bodies (Fig. 62. 2). 

 Whether these latter are real funnels, and whether they are con- 

 stantly found, it is not possible to decide from the few specimens 

 available. 



Only few species are entirely without miliary granules in the 

 body-wall, as there are usually minute oval bodies in the longitud- 

 inal muscles, whereas rods are wanting in the skin. When rods are 

 present attention must be paid, not only to their shape, but also 

 to their arrangement, both whether they are confined to the radii 

 or not, and whether they are equally found on the ventral and 

 dorsal side of body. The rods in albatrossii and pacifica are usually 

 totally confined to the anterior end of the dorsal side. If in these 

 species pieces for examination are taken from the ventral side or 

 from the posterior end of the body, the specimens might be referred 

 to lœvis Fabricius. 



The calcareous ring consists in all species examined of twelve 

 pieces. In the literature only SI u iter has mentioned a 12-ten- 

 tacled Chiridota with more than 12 pieces in the calcareous ring 

 {Chiridota liberata is said to have 15). But as at any rate the 

 statement in the description of liberata that it has three ventral 

 interradiais may be erroneous, we may well suppose that the same 

 is the case with that of the 15 pieces in the calcareous ring. The 

 two extra interradiais are, in all species known, found in the lateral 

 interradii, one in each. The radial pieces of the calcareous ring have 

 usually a passage for the nerve and only gigas has, according to 

 Dendy the radiais neither notched nor perforated. 



The passage for the nerves is in most species a hole through 

 the anterior part of the radiais, and only liberata and hawaiiensis 

 are said to have the radiais notched. The examination of the spec- 

 imens of hawaiiensis at hand shows that we have here a much more 

 interesting case. In all the specimens examined the three ventral 

 radiais are notched in the margin, and thus they agree with Fisher's 

 figure PI. 82 fig. 3d, but the two dorsal radiais are quite different, 

 being perforated as in most other species. Furthermore I find that
