This species was formerly known only from a single place 

 in Greenland, Godthaab (Rosenv. Deux. Mém. 1. c). The spe- 

 cimens I have had for examination occurred in company with 

 Ulofhrix consociata Wille and were all young and small. The 

 stipe was 102// long, the head 51// long and 6/^ broad. The 

 head is distinctly marked from the stipe by a constriction. 

 It was collected sterile in July in the littoral region.
