ague showed .1 ver) slightlj yellowish radula containing i'> tooth-plates (34 on the lower 

 the upper one), and two were further found lying loose posteriorly at the base ol tin- 

 in tlu- radula-sheath 20 tooth-plates were seen, of which the three hindmost ones were not 

 ped; thus the total cumber of tooth-plates was 66'). The tooth-plates were yellowish; 

 the) had .1 breadth of 006 b) a height of 0*04 . and were of the- earlier described form with 6 

 nted denticles on each side of the but little strong hook (figs. 25 27). 



The liver-lobes were as before mentioned. The pyriform cnidocyst was in the largest pa- 

 pill., long; the cnidse were roundish, their largest diameter 0-007 — o - oi3 mm . 



The penis was as described before; the colourless hook that was slightly curved, and at the 

 end, as it were, obliquely cut off, (fig. 28a) was about iroj mm long,

The- Galvinae form a rather well marked group. Even their exterior is remarkable by the 

 dorsal papillae being, as it were, somewhat inflated; they show, however, especially a quite 



diar .structure of the radula, which has strong median teeth, the hooks of which are, as it 

 were, bent down and situated below the level of these teeth; tile lateral teeth are very broad, 

 and their inner part projects backwards in a lanceolate hook. 



The Galvinae .seem chiefly to belong to the less warm tracts of the sea.

ther with some specimens of Coryphella salmonacea (mentioned above) another little Aeo- 



lidia was taken, which, in a short notice, is said to have been whitish with red dorsal papillae. 



The individual, which was only middlingly preserved in alcohol, was of a yellowish white 



iur. Its length was io mm , by a breadth of the body of up to 3 , and a height of up to 2-5 mm . 



The rhinophores were 2 mm long, the tentacles i mm , and the (remaining) dorsal papillae likewise only 



The form was the common one. The lateral parts of the back that were covered with pa- 

 pilla more narrow than the naked middle part; the number of series of papillae was not large, 

 and the number of papillae in a series exceeded scarcel) '>. The papillae were conical, partly some- 

 what inflated, a great deal had fallen off. The foot was anteriorly rather broad, almost without 



ly known individual, only the bulbus pharyngeus was examined It showed 

 Mil, the radula formed a cone on the hinder end; the length was 2-3 , b) a breadth 



camined specimens was 67, 61, 64; in A. cotruUa it was (*>. 57, 60.
