54 ANTIPATIIES. 



chassaing and Michellotti had evidently specimens with dried polyps 

 before them, which give to the branchlets the appearance described by 

 them.) Spines confined only to the smaller branches and branchlets, 

 few, small, and rounded, thus having under the microscope a aipple- 

 shape appearance in profile, though flattened longitudinally. 



Polyp large, resembling in their proportions those of A. arborea, as 

 represented by Dana. They are all on one side of the branchlets (not 

 the upper or lower), and generally the row is composed of alternately 

 large and small polyps. The mouth surmounts a tubercle and is elon- 

 gated transversely to the branch, as has been observed by Lacaze- 

 Duthiers in other species of the genus. The tentacles are elon- 

 gated, conical, and do not appear susceptible of much contraction, but 

 can be curled up over the mouth. They are never found contracted 

 into small knobs, as in some species hereafter described. The largest 

 specimen obtained is one meter high, the main stem being 2 cm. in 

 diameter. Pinnules 3 or 4 cm. long. 



OAT Alligator Reef, in 110 fathoms. 

 Off Sin-I Key, in 125 fathoms. 

 Off Coffin's Patches, in 195 fathoms. 

 Off Bahia Honda, in 324 fathoms. 



Antipathes filix Pourt. 



Anlipalhes Jilix Pourt. Bull. Mus. Cjmp. Zool., Nj. 6. 



Main stem simple, pinnate ; the pinnules setting off nearly at right 

 angles, rather short, alternate, covered with spines or short, stiff hairs, 

 and showing a succession of slight swellings and contractions. Soft 

 parts not observed. 



Height about 7 cm. 



Every specimen obtained served as support to the tube of an An- 

 nelid. * 



Off Havana, in 270 fathoms. 



Antipathes humilis Pourt. 

 Antipathes humilis Pourt. Bull. Mus. Comp. Zool., No. 6. 



Corallum flabellate, irregularly dichotomous, spreading more laterally 

 than vertically, hirsute, the spines being slender and longer than the 

 diameter of the branchlets, which are alternately swollen and con- 



* The specimens having been sent to Professor Ehlers with the collection of Annelids, I have 

 been prevented from comparing the polyps with those of the other species since obtained.
