Family MONOPHYID^S. 



Sph&ronectes gracilis (Claus). 



Fewkes, 1881, p. 143; Hargitt, 1904, p. 61. 

 Newport. Fewkes. 



Family 



Diphyes bipartite, Costa. 

 Hargitt, 1904, p. 59. 



Often taken at Newport. Mayer. "Not infre- 

 quently drifts into the bays of the region from 

 the Gulf Stream." Hargitt. 



Diphyopsis campanulifera Eschscholtz. 

 Hargitt, 1904, p. 60. 



"Frequently taken in the deeper tows, particu- 

 larly south of Marthas Vineyard and in the 

 region of Nan tucket." 



Family AGALMID/B. 



Cupulita cara Agassiz). 



A. Agassiz, 1865, p. 200 (Nanomia cara); Fewkes, 

 1881, p. 163 (Agalma elegans)? Hargitt, 1904, 

 p. 60. 

 Newport. A. Agassiz. 



Family ANTHOPIIYSID/E. 



? Anthophysaformosa (Fewkes). 

 Hargitt, 1904, p. 60. 



A single specimen taken "south of Marthas Vine- 

 yard " in the summer of 1902 (beyond limits of 

 region?). 



Family PHYSALIDJE. 



Physalia pelagica Bosc. Portuguese man-of-war. 



A. Agassiz, 1865, p. 214 (Physalia arethusa); Ver- 

 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 Sound. 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. 



Class SCYPHOZOA. 



Family CHARYBDEID^. 



Charybdea -verrucosa Hargitt. 

 Hargitt, 1902 a, p. 559, 560 (sp. nov.); Hargitt, 



1904, p. 65. 



Great Harbor, Woods Hole; North Falmouth; 

 several specimens, August 13 and 14, 1901. 



Family EPHYRID^. 

 ? Bathyluca Solaris Mayer. 



Mayer, 1900, p. 2 (sp. nov.); Hargitt, 1904, p. 66. 

 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^S. 

 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 



Aurelia flamdula Continued. 



that sexual reproduction occurs in summer, 

 the resulting scyphistoma larvae remaining in 

 that condition till the following spring, when 

 ephyrae are produced. 



Family CYANEID^. 



Cyanea arctica Peron & Lesueur. 



A. Agassiz, 1865, p. 44 (Cyanea arctica), p. 46 

 (Cyaneafuha)- Verrill and Smith, 1873, p. 723, 

 449, etc.; Fewkes, 1881, p. 166; Bumpus, 1898, 

 p. 487; 18983; 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. 



a Mayer (1910, p. 385) now thinks that the type of this species (?) was probably a "damaged and regenerating specimen" of 

 Dactylometra quinquecirra.
