the ri^lit rhinophore a rather long and rather strongl) projecting told was seen running towards the 



amis; tlu- fore end (praeputium penis) of this told projected 5""" in a lobelike manner, and behind and

the side of tin- body the anal papilla was found directed a little upward, and before it the little 



ipilla (fig.6d). The foot is powerful, the rounded fore end with a deep marginal furrow (fig.6), 



and medianly emarginate upper lip; the foot-brim not narrow; the tail flat, lanceolate, rather short 



At the uppermost part of the sides of the body towards the dorsal edj^e the liver shone through 

 •lite small, slightly yellowish white grains; similar grains, but more powerful (for a great part 

 with mark from fallen-off papillae) were seen on the lateral parts of the back towards the papillae. 



The central nervous system showed almost the same structure as was seen by the 

 preceding examination 2 ] of the typical species; especially on account of the contractility of the 

 enclosing loose capsula, the absolute and relative form and size of the different ganglia vary not a 

 little in the Xudibranchiata. The boundary between the cerebral ganglia and the pleural ones 



rather distinctly marked, and the pedal ganglia (fig.8b) a little larger than the cerebro-pleural 

 The strong ganglia rhinophorialia (olfactoria) (fig.8c) were rather short-stalked; the buccal 

 flia and the gastro-oesophagal ones (fig. 8d) were as before described. The pedal commissure 

 ible one. before it the much thinner pleural one was seen, and in front a subcerebral com- 

 pare.

they were almost sessile, of a diameter of about - l6 mm , with a black pigment and a yellowish lens.

The mandibles were as long and high as the bulb, light amber coloured, only the crista coiniectiva 



and the m,. edge yellowish brown (fig. 9); in front on the outside was seen a short, strongly
