Very rare: 31. VIII. 76° 27' N. 10° 43' E. Temp. 5,36. Sa]. 35,03. Pl. S. 



T. mimitus Beandt. As I have seen no figure of this species I am somewhat 

 uncertain about the identification. The form which I suppose to be T. minutus is figured 

 ill the Pl. I, fig. 3 and difters from T. gracilis Brandt in the less close teeth only, so 

 that the above name probably comprises both. Diam. Q,03; height 0,05 mm.
