The specimen that was rather well preserved in alcohol, was of a whitish colour; its length 



. the other measures relatively as in the following species. 

 The form was as in the typical species, the dorsal lateral edges more projecting than in the 

 .wing species; the corners and the fore edge of the foot distinctly projecting, more so than in 

 both the other species; the flaccid, dorsal papillae, many of which had fallen off, rose to a length of 

 6 mm ; the genital openings wen- quite as in the typical species, and so was the anal papilla. 



The central nervous system together with eyes and otocysts were as in the species de- 

 bed below. 



The bulbus pharyngeus was to a remarkable degree like that in Chlamylla borealis 1 ), and 

 ise hollowed in the hinder part of the upper surface; it was | broad l>y a length and 

 height ol The lij^ht yellow mandibles had the same form as in the following species; only 



the keel in front on the outside was a little slighter; the masticator} process and th« masticat 



described below. The tongue was quite as in the following species; in the co- 



radula 8 series of teeth were seen, and as many in the short radula sheath, which was directed 



.ward; thus the total number of series was [6, of which the two hindmost ones were not yet 



quit< ped. The tooth-plates were almost quite colourless; the breadth of the median teeth rose 



a height ol and a length ol ; the length of the lateral teeth rose to o-2o mm .

ng denticles were seen. The lateral tooth-plates (figs. 15b, 17I0 were shorter 



and • than in both the other species, and without denticulation.
