1 sp., 1. 10 (det. as „D. crassicornis^), and 1 sp., 1. 4 („D. 

 crassicornis^^) — Sandøsund, 1 sp., 1. 8. 



Doto crassicornis M. Sars. Drøbak, 2 sps., max. 1. 4.5 

 (prototype). M. Sars described this species in 1870 on the base 

 of 4 specimens from Drøbak, 50 — 60 fms, of which 2 are at pre- 

 sent still kept. Beside them the species is known from Bergen, 

 100 fms, off Kristiansund, 40—60 fms (Friele & Hansen 1876) 

 and from Bohuslän, Kosterfjorden, 20—40 fms (Odhner 1907). 

 The teeth of the radula do not differ essentially from those of 

 the other species. Friele & Hansen have found in the teeth only 



2 strong denticles on each side of the median cusp; in the specimen 

 from Kostertjorden, which I have examined, there are 4 — 5 (also 

 somewhat stronger than in the remaining species, fig. 14 d).
