1 64 ANNALS OF SCOTTISH NATURAL HISTORY 



D. bullatiim, n.sp. Figures 20, to if. Specific characters. Short, 

 broad. Body in section somewhat trilobate, two narrow lateral 

 flanges separated from the median dorsal mass, the dorsal 

 portion bearing at each apparent segment of the body a pair of 

 rounded low prominences ; on the anterior part of the body 

 the processes of each pair touch, behind they are widely 

 separated. Skin all minutely papillose, papillae larger on the 

 dorsal bosses. Teeth curved, divergent, with bearers ; gullet 

 long, slender, the flexible portion longer than the pharynx. 

 Pharynx shortly elliptical, nearly as broad as long ; three 

 thickenings in each row, two equal narrow rods and one small 

 nut (at posterior end). Claws, one of each pair longer than 

 the other, and that of one pair much longer. Resembling 

 D. chilense in the nearly round pharynx and slender gullet, it 

 differs in having fewer thickenings in each row, in the papillose 

 skin, and the two rows of bosses on the back. The legs are 

 short, and the last pair unusually divergent. In moss, south 

 shore of Loch Leven, 8th April 1905 (W. Evans), two 

 examples. Size -^ inch.
