20 NUDIBRANCHIATE c.ASTEROPODA. 



veil was 8 mm , its length 5 mm , half of which belonged to the fingers; the height of the sheaths of the 

 rhinophoria was 2 ,nm , of the branchial tnfts np to 3 ram ; the breadth of the sole of the foot was np to 

 i2"" n , of the foot-brim np to o75'" m . - The animal seemed to have imparted a peculiar odonr to the 

 alcohol in which it was kept. 



The form was as in other Candiellae. The animal was longish, highest in the middle, and 

 sloping from there forward and especially backward where the back ultimately passed into the foot. 

 The fore edge of the frontal veil was a little notched in the middle, and had on each side of the 

 notch 6 fingers, and outermost the only little conspicuous tentacle with its furrow. At the base of 

 the veil were seen the somewhat projecting sheaths of the rhinophoria; the strongly retracted club 

 was 2 - 5 mm high, and of the shape common in the Tritoniae, resembling a sword-knot, and the 

 rhachis of the hindmost leaf was prolonged in the usual way. The back was smooth: the edge of the 

 back that only projected a little, had on each side 12 — 14 small and short-branched branchial tufts, 

 of which the foremost one projected outside the sheath of the rhinophore. The sides of the body 

 were rather high, a little convex, and a little sloping inward towards the foot; the genital papilla was 

 situated about under the the fifth (right) branchial tuft, the anus under the eighth, and close above 

 it the renal pore. Anteriorly the foot was rounded, with a strong marginal furrow: the foot-brim 

 was narrow. 



The peritoneum was bluish black, and continuations of its connective tissue penetrated 

 everywhere between and wrapped the entrails. 



The yellowish white central nervous system showed a rather closely adherent, dense, and 

 finely black punctuated wrapping; as in other Tritoniadae it was rather flat, 4" lm broad. The cerebro- 

 pleural ganglia were of oval shape, 2 mm long, a little broader anteriorly, the separation between their 

 two parts was only little conspicuous; the roundish pedal ganglia were almost as large as the cerebral 

 ones; the' large commissures were half as long again as the breadth of the central nervous system. 

 The buccal ganglia were oblong, o-6 n,m long, connected by a short commissure; the long-stalked gastro- 

 sesophagal ones quite small, roundish. 



The o to cyst is situated closely before the quite short eerebro-pedal connective, containing a 

 not large number of otoconia. 



The large bulb us pharyngeus was 13"" 11 long by a breadth of 9""" and a height of -j mm , 

 being thus one fifth of the whole length of the body; it was lying in a rather loosely attached veil- 

 like wrapping. Its form and structure in all respects as in other Tritoniae. The mandibles covered 

 with the common thick muscular plate, were greenish yellow, only the hindmost part of the hinge, 

 and the portion nearest to the masticatory edge were brownish; the length of the mandibles was I3 mm , 

 by a breadth (behind) of 4-4""", and a height (of the convexity) of 3 - 5' nm , the length of the masticatory 

 prolongation was 3 mm . The masticatory edge was slightly convex, even, of a breadth of up to 04'""', 

 under the magnifying glass, as it were, finely transversely striated; it had 8 — n series of short, round- 

 ish-edged columns, of a height of up to crio mm , and a diameter of up to o - o8 mm (fig. 4), the series 

 being somewhat displaced among each other; in the outermost series many of the columns were torn 

 out, and many were worn away and upset more inwardly. - The pharynx was black, the buccal 

 cavity grayish white. — The strong and broad tongue had at the base the powerful tectum radulse
