Hargitt, 1904, p. 60. 
A single specimen taken “south of Marthas Vine- 
yard” in the summer of 1902 (beyond limits of 
region?). 
Family Physalid^. 
Pkysalia pelagica Bose. — Portuguese man-of-war.

rilland Smith, 1873, p. 737,450; Hargitt, 1904, 
p. 25, 61. 
Taken nearly every summer in Vineyard Sound, 
sometimes in considerable numbers, occasion- 
ally drifting into Woods Hole Harbor. On 
July 7, 1904, Mr. John J. Veeder collected 78 
specimens in the Soimd. During some sum- 
mers, on the contrary, none are observed. It 
is probable that the abundance of this species 
varies directly with the quantity of material 
which is blown to our shores from the Gulf 
Stream. Physalia has been observed locally in 
July, August, and September.

Narragansett Bay; a single specimen found July 
27, 1896. Latter “ much torn and battered . . . 
may prove to be a deep-sea form.” — Mayer. 
Family Ulmarid/E. 
Aurelia flavidula Peron & Lesueur. 
Verrill and Smith, 1873, p. 723, 449, etc.; 
Fewkes, 1881, p. 172; Bumpus, 1898, p. 487; 
Hargitt, 1904, p. 67; Mayer, 1910, p. 623 ( Au - 
rellia aurita). 
Common throughout local waters during spring 
and summer. Young stages recorded by sev- 
eral observers as early as March; adults found 
as late as September. According to Mr. 
Edwards, Aurelia appears in the tow most fre- 
quently in May. Dr. Hargitt thinks it likely 
Dactylometr a quinquecirra.

that sexual reproduction occurs in summer, 
the resulting scyphistoma larvae remaining in 
that condition till the following spring, when 
ephyrae are produced. 
Family Cyaneid/E. 
Cyanea arctica Peron & Lesueur. 
A. Agassiz, 1865, p. 44 ( Cyanea arctica), p. 46 
(Cyanea fulva)- Verrill and Smith, 1873, p. 723, 
449, etc.; Fewkes, 1881, p. 166; Bumpus, 1898, 
p. 487; 1898a; Mead, 1898, p. 705; Hargitt, 
1904, p. 68; Mayer, 1910, p. 597 (Cyanea capil- 
lata, var. arctica). 
Very common throughout the region during the 
spring and summer. Both Mr. Edwards and 
Mr. Gray report the occurrence of this species 
from March till September. About a dozen 
specimens, several inches in diameter, were 
taken in a fyke net by Mr. Edwards, February 
28, 1908. Ripe eggs reported by Bumpus in 
May and early June, by Hargitt in July. The 
early stages may readily be reared in aquaria. 
Verrill and Mead note the occurrence of ephyrae 
in April. 
0 Mayer (1910, p. 585) now thinks that the type of this species (?) was probably a “ damaged and regenerating specimen ” of 
uecirra.
