4 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT 



Eudendrium tenellum Allman 

 Eudendrium tenellum Allman, Gulf Stream Hyd., 1877, p. 8. 



Fraser, Atlantic Hyd., 1944, p. 74. 



Distribution. — 2 miles southwest of Cape la Vela, 21-22 fathoms; 3 

 miles north of Coche Island, 21-22 fathoms. 



These records are not far to the southwestward of Grenada Island 

 but they take the species a little nearer to the numerous locations in which 

 it has been found in the Eastern Pacific, from the Galapagos Islands and 

 the coast of Ecuador, to San Pedro Nolasco Island in the Gulf of Cali- 

 fornia. 



Family Gladocorynidae 



Genus GLADOGORYNE 



Cladocoryne pelagica Allman 



Cladocoryne pelagica Allman, Jour. Linn. Soc, 1876, p. 255. 



Fraser, Atlantic Hyd., 1944, p. 108. 



Distribution. — Tortuga Island, 2-5 fathoms. 



This location is a long way from Vineyard Sound and similarly far 

 from the two far apart locations at which it has been reported in the 

 Eastern Pacific, Santa Elena Bay, Ecuador and Braithwaite Bay, Socorro 

 Island, but it is also scattered widely in other directions. The fact that it 

 has been found commonly on floating sargassum may help to account for 

 the worldwide range. 



Sub-order GaLYPTOBLASTEA 



Family Gampanularidae 



Genus CAMPANULARIA 



Campanularia (?) certidens, new species 



Plate 1, Fig. 1 



Trophosome. — Individuals grow from a filiform stolon with little 



evidence of reticulation. As the pedicel is not of great length, the whole 

 zooid is but 1.5 mm in height or less. The pedicel is strongly wavy 

 throughout rather than annulated ; at the distal end, supporting the 

 hydrotheca, there is a spherical portion with an annulation above and 

 below it. The hydrotheca (0.5x0.27 mm) is well proportioned with 

 the sides regularly but slightly convex and the diameter gradually increas- 

 ing from base to margin. On the margin, the 10 teeth are distinctly cut, 

 the tooth having parallel sides except near each end ; the tip of the tooth 

 is smoothly rounded, and the base of the sinus similarly so.
