 SARSIA MIRABILIS L. Agassiz. 



Plate 30, fig. 2. 

 Sarsia mirabilis L. Agassiz, '49, p. 228, pis. 4, 5. 



One specimen, about 10 mm. high, from St. Pierre, ofp Newfound- 

 land, October 1, probably belongs to this well-known species, judging 

 from its size and from the color of its tentacular bulbs and ocelli. 

 Unfortunately, however, both manubrium and tentacles are so 

 strongly contracted as to make positive identification impossible. 



S. mirabilis is known not only from the Atlantic coast of North 

 America, Baffin's Bay, Greenland, and probably northern Europe 

 (Hartlaub, :07, p. 39), but also from the Pacific coast of North 

 America, a fact omitted in my summary of the Pacific Sarsiae. (:09). 

 It is likewise recorded, though with reservation as to its true identity, 

 from the coast of Chile, by Hartlaub (:07, p. 39).
