MEDUSAE. I. 



summer of 1849. Sars also found a single specimen near Christiansund. Broch (1905, p. 7) records it, 

 though with some doubt, from Puddefjord at Bergen. 



East coast of Scotland. Peterhead, May-June (Peach 1868, p. 97); St. Andrews (Me In tosh 



1890, p. 4)- 



Heligoland. Young specimens about April ist, full-grown specimens at the end of May 1895 

 (Hartlaub 1897, p. 484^ 



North Atlantic area, western part: 



West coast of Greenland. All specimens hitherto known from Greenland (Levin sen 1892, 

 p. 145; Kramp 1913, p. 269 aud 1914, p. 420) have been mentioned above. 



East coast of North America. New Foundland: Fogo Island, at the surface in July (Bigelow 

 1909 b, p. 307). -- New England: Grand Manan (Stimpson 1854, p. n; Fewkes 1888 a, p. 233); East- 

 port (Verrill 1872, p. 6); Massachusetts Bay (L. Agassiz 1849, p. 30off.; A. Agassiz 1865, p. 136); 

 Woods Hole (Hargitt 1902, p. 553 and 1904, p. 43 44); Fishers Island Sound (Verrill 1875, p. 43); 

 Frye's Island, New Brunswick (Fewkes i888a, p. 233). Bigelow, in a series of papers (19143, 

 p. 123124; 1914 b, p. 12; 19140, p. 407; 1915, pp. 267, 273, 274, 319, 320), has dealt with the occurrence 

 of this species off the coasts of New England. It appears from his statements that Staurophora mer- 

 tensii is common north of Cape Cod, whereas sout of this point it occurs only occasionally, and then 

 only in the spring. In the Gulf of Maine it is "a constant inhabitant", though it occurs particularly 

 in the neighbourhood of the shore; Bigelow states that this is not surprising "because it is 

 undoubtedly neritic" (19143, p. 124). Young specimens are found at the end of April or at the begin- 

 ning of May; thus many very young stages were found in Gloucester Harbour on May 3rd 1913 (op. 

 cit 19140); these young stages probably "have passed through the fixed stage in the near neighbor- 

 hood". On Msy i7th of the same year several specimens were found, about 2 inches (5 cm) wide. 

 Grown-up individuals are found in June, July, and August. During the investigations in July and 

 August 1913 (op. cit 1915) Staurophora occurred in the whole of the Gulf of Maine, but not south of 

 Cape Cod. Hargitt (1902 and 1904) has found the species in considerable numbers at Woods Hole, 

 but he remarks: "Its occurrence seems to be somewhat erratic, however, as I have taken specimens 

 but twice within recent years" (1904, p. 44). 



The American investigations show that Staurophora mertensii is indigenous to the Gulf of 

 Maine and breeds here; further that in the said area its occurrence is not limited to the cold water; south 

 of Cape Cod, on the other hand, it is only an occasional visitor, and in the hot season of the year it 

 is quite absent from that area. 



Northern Pacific: 



Norfolksound ; in the Ocean as far as Unalaschka and between Sitka and the Aleutean Is- 

 lands (Brandt 1835); Dutch Harbor aud Prince William Sound, Alaska (Bigelow 1913); Sachalin 

 and northern part of Japsn (Kishinouye 1910). In short, it occurs slong the southern coast of Alaska, 

 but not off the west coast of North America south of Sitka; further along the coast of Asia as far 

 south as the northern part of Japsu. 



Falkland Islands: 



January 7th 1903 (Browne 1907, p. 473 an d 1908, p. 235).
