ANTIPATHES FERNANDEZII, 47 



Antipathes abietina n. sp. 

 PI. IX. fi(j. 10. 



Stem simple, or emitting a few simple branches from the base, stiff, erect, 

 hirsute, beset with short, simple pinnules on all sides, not verticillate. This is 

 the principal difference from A. fllix, which is pinnate. Pinuules nodose, be- 

 set with cylindrical spines. Polyps of the type with short tentacles, sur- 

 rounded by longer spines than those on the rest of the pinnule. Height 

 10 cm. Pinnules about 1 cm. long. 



Every specimen has one or two worm-tubes attached to the stem, as in 

 A.filix (see Bull. Mus. Comp. ZooL, No. VI.). 



Barbados, 100 fathoms. 



Antipathes lenta Pourt. 

 Barbados, 100 fathoms. 



Antipathes Fernandezii n. sp. 



Main stem imknown. Branchlets pinnate, with alternate and rather long 

 pinnules. Densely hirsute with short spines disposed in longitudinal rows. 

 Spines somewhat compressed and hooked upwards near the tij). Polyps 

 elongated, with short tentacles, rather crowded on upper part of pinnules. 



Off Juan Fernandez, in 65 and 220 fathoms. 



The works of Milne-Edwards and Haime, Reuss, Duncan, Seguenza, and 

 others, give us the means of making a comparison between the living West 

 Indian coral fauna, both littoral and deep-water, and the fauna of the Euro- 

 pean tertiary formations. The resemblance between the two is a very strik- 

 ing one, as can be seen at a glance in the following table, where the genera 

 common to both are enumerated, the living ones being separated according 

 to their habitat in the littoral or the deep-sea zone. In a few cases the near- 

 est allied genus has been taken as the representative of the extinct one.
