1898-1902. No. 8.] BRYOZOA. 15 



23. Hippothoa divaricata, Lamouroux. 



Syn. BiDENKAp kat., p. 17. 

 July, 1900, the winter haven and adjoining waters, on stones. 



Gen. Leieschara, M. Sars^. 



24. Leieschara subgracile, D'Orbigny 

 Syn. BiDENKAP kat., p. 18 (Myriosoum subgracile). 



July 22, 1901, the winter haven, fine colonies, about 30 fathoms. 



If Myriozoum truncatum, Pallas, can be placed in the same genus 

 as subgracile and coardata, which Canon Nokman doubts, the name 

 Leieschara must give place to Myriozoum, Donati. Leieschara coarc- 

 lata, M. Sars, is known from Alaska, Greenland, the north of Norway, 

 Jan Mayen, Spitsbergen and Franz Josef Land; and subgracile has a 

 similar distribution, except that it has not, up to the present, been found 

 in the north of Norway. 



Gen. Schisoporella Hincks. 



25. Schizoporella plana, Dawson. 



August 24, 1898, Rice Strait, on algae; July, 1900, the neighbour- 

 hood of the winter haven, incrusting stones; June 28, 1901, the mouth 

 of Hvalros Fjord, incrusting stones; July .8, 1901, Ren Bay, on algae; 

 July 19, 1901, Gaase Fjord, incrusting stones; July 15, 1902, off Hav- 

 hest Mt., N. Devon, incrusting stones. 



Hincks 2 and Norman ^ agree in thinking that the form that Smitt 

 described under name of Myriozoum crustaceum is identical with Le- 

 pralia plana, Dawson^. Waters^ transferred the species to the genus 

 Schizoporella, which is indeed its right place.
