Gen. Escharella, Gray. 

 Mu cronella, Hincks ' . 

 49. Escharella ventricosa, Hassall. 



Syn. BiDENKAP Kat., p. 27 (Mucronella). 



July 22, 1900, the winter haven, upon algae and incrusting stones; 

 Aug., 1900, the north side of N. Devon incrusting stones; Sept. 20, 1900, 

 the head of Gaase Fjord, on algae; July 12, 1901, bay at Land's End, 

 on algae; July 13, 1901, a little north of Cape Land's End; July 15, 

 1902, off Havhest Mt., N. Devon, incrusting stones. 



This species appears to be fairly common in the region investigated 

 by the 2nd Fram Expedition. 



50 & 51. Escharella abyssicola, Norman & laqueata, Norman. 

 Syn. BiDBNKAP Kat., p. 28 & 29 (Mucronella). 



July 22, 1900, the neighbourhood of the vi'inter haven, incrusting 

 stones; Aug., 1900, the north side of N. Devon, incrusting stones; Aug. 3, 

 1900, Fosheim's Peak and the valley on the west side of the fjord. 



The commonest Escharella is ventricosa, but there also occuri-ed a 

 form with much larger zocecia, and with the peristome drawn out. 



This should probably be referred to abyssicola, although spe- 

 cimens also occurred that were more like laqueata. The relation 

 between abyssicola and laqueata ought to be more closely investigated ; 

 but at present I have not sufficient material for that purpose. 



52. Escharella labiata. Boeck. 

 Syn. BiDENKAP Kat. p. 28 (Mucronella). 



Aug., 1900, the north side of N. Devon, incrusting stones. 



Among some detached colonies, a few zoojcia of this species were' 

 also found. They were recognisable by their short, broad, median den- 

 ticle and the lateral perforation.
