On the 10 th of May 1S95 two specimens probably of this species were taken at Trangisvaag. 



One individual had a length of 4 mm , the other of 5 - 5 mm , by a height of about i mm , and a breadth 

 of almost 0'75 mm ; the height of the papillse rose to about r25 mn '. The body had a yellowish white 

 colour, the head was whitish, the dorsal papilke were brownish gray with a whitish point. 



The form was the common one. The body was lengthened and narrow; the smooth, a little 

 truncate rhinophores and tentacles were not long. The papillse were arranged in six groups with 

 two, sometimes three papilke in each; in the groups in front the papilke were smaller, and in the 

 hindmost group they were quite small; the two inmost papillae were of about equal size, and in 

 the three groups very powerful, short-fusiform; if a third papilla was found it was alw.i\ s much 

 smaller. The anal papilla was situated immediately at the outer edge of the fourth group of papillse. 

 The foot was narrow, anteriorly a little broader, with rounded corners; the tail was short.
