104 THE BERMUDA ISLANDS. 



on the shallows known as Devonshire Flats. We failed to 

 obtain any of the yellow forms, and I am not positive that 

 this variety has ever been found at the Bermudas. 



Gorgonia (Plexaura) purpurea, Pallas. 

 Gorgonia (Plexaura) flexuosa, Lamouroux. 



This species, of which we obtained several specimens, is, I 

 believe, without doubt the Gorgonia angniculus of Dana (U. S. 

 Exploring Expedition, Zoophytes, p. 668). It is referred to 

 under Lamouroux's name as a member of the Bermudian 

 fauna in Dana's "Corals and Coral Islands," p. 114, 1872. 



Gorgonia (Plexaura) homomalla, Esper. 

 Gorgonia (Plexaura) multicauda, Lam. 



Gorgonia crassa, Ellis and Solander. 



G. vermiculata, Edwards and Haime. 



The exact limitations and synonymy of this species are 

 difficult to make out, but as far as my studies have permitted 

 me to analyze the forms above indicated from the rather in- 

 sufficient or deficient descriptions that have been furnished by 

 their authors, they appear to represent an identical form. 

 As such I have accordingly referred them in this list. 



Gorgonia (Plexaura) dichotoma, Esper. 



A single specimen, measuring about a foot and three-quar- 

 ters in height, with the main stems somewhat over a half-inch 

 in diameter. 



Gorgonia (Eunicea) pseudo-antipathes, Lam. 



One much branched specimen, and another, slightly differing, 

 which appears to belong to the same species. 



Pterogorgia acerosa, (?) Pallas. 



A single specimen of a large Pterogorgia, entirely stripped 

 of coenenchyma, and measuring about two and a-half feet in 

 height, was obtained through purchase at the Crawl. The 

 axial skeleton is yellowish, or of the color of earth. The 

 terete branches are much more broadly spreading than in P. 

 setosa, and unite into a common basal stalk which is upwards 

 of two inches in thickness. The pinnules are very numerous,
